+# Releasing vLLM
+
+vLLM releases offer a reliable version of the code base, packaged into a binary format that can be conveniently accessed via PyPI. These releases also serve as key milestones for the development team to communicate with the community about newly available features, improvements, and upcoming changes that could affect users, including potential breaking changes.
+
+## Release Versioning
+
+vLLM uses a “right-shifted” versioning scheme where a new patch release is out every 2 weeks. And patch releases contain features and bug fixes (as opposed to semver where patch release contains only backwards-compatible bug fixes). When critical fixes need to be made, special release post1 is released.
+
+* _major_ major architectural milestone and when incompatible API changes are made, similar to PyTorch 2.0.
+* _minor_ major features
+* _patch_ features and backwards-compatible bug fixes
+* _post1_ or _patch-1_ backwards-compatible bug fixes, either explicit or implicit post release
+
+## Release Cadence
+
+Patch release is released on bi-weekly basis. Post release 1-3 days after patch release and uses same branch as patch release.
+Following is the release cadence for year 2025. All future release dates below are tentative. Please note: Post releases are optional.
+
+| Release Date | Patch release versions | Post Release versions |

+## Release branch
+
+Each release is built from a dedicated release branch.
+
+* For _major_, _minor_, _patch_ releases, the release branch cut is performed 1-2 days before release is live.
+* For post releases, previously cut release branch is reused
+* Release builds are triggered via push to RC tag like vX.Y.Z-rc1 . This enables us to build and test multiple RCs for each release.
+* Final tag : vX.Y.Z does not trigger the build but used for Release notes and assets.
+* After branch cut is created we monitor the main branch for any reverts and apply these reverts to a release branch.
+
+## Release Cherry-Pick Criteria
+
+After branch cut, we approach finalizing the release branch with clear criteria on what cherry picks are allowed in. Note: a cherry pick is a process to land a PR in the release branch after branch cut. These are typically limited to ensure that the team has sufficient time to complete a thorough round of testing on a stable code base.
+
+* Regression fixes - that address functional/performance regression against the most recent release (e.g. 0.7.0 for 0.7.1 release)
+* Critical fixes - critical fixes for severe issue such as silent incorrectness, backwards compatibility, crashes, deadlocks, (large) memory leaks
+* Fixes to new features introduced in the most recent release (e.g. 0.7.0 for 0.7.1 release)
+* Documentation improvements
+* Release branch specific changes (e.g. change version identifiers or CI fixes)
+
+Please note: **No feature work allowed for cherry picks**. All PRs that are considered for cherry-picks need to be merged on trunk, the only exception are Release branch specific changes.

+# DeepSeek DeepGEMM Kernels Benchmark
+
+This directory includes benchmarks between DeepSeek's DeepGEMM block fp8 kernels against vLLM's existing triton and CUTLASS-based kernels.
+
+Currently this just includes dense GEMMs and only works on Hopper GPUs.
+
+## Setup
+
+You need to install vLLM in your usual fashion, then install DeepGEMM from source in its own directory:
+
+```
+git clone --recursive https://github.com/deepseek-ai/DeepGEMM
+cd DeepGEMM
+python setup.py install
+uv pip install -e .
+```
+
+## Usage
+
+```
+python benchmark_fp8_block_dense_gemm.py

+// from https://github.com/NVIDIA/cutlass v3.5.0
+// It has been modified to support either row/column or scalar broadcasting
+// where the tensor being loaded from is always passed in via a device pointer.
+// This lets one compiled kernel handle all cases of per-tensor or
+// per-channel/per-token quantization.
+//
+// This interface also allows the scales to be passed in as tensors that
+// consistently reside on the device, which avoids an issue with a previous
+// implementation where scalars needed to be on the CPU since they
+// were passed in via float values. This created a potential performance hazard
+// if scales were initially on the device, and caused torch.compile graphs
+// breaks when moving scales to the CPU.

+## Notes
+
+### Inserting feature tokens without replacement
+
+Some HF processors directly insert feature tokens without replacing anything in the original prompt. In that case, you can use {class}`~vllm.multimodal.processing.PromptInsertion` instead of {class}`~vllm.multimodal.processing.PromptReplacement` inside {meth}`~vllm.multimodal.processing.BaseMultiModalProcessor._get_prompt_updates`.
+
+Examples:
+
+- BLIP-2 (insert at start of prompt): <gh-file:vllm/model_executor/models/blip2.py>
+- Florence2 (insert at start of prompt): <gh-file:vllm/model_executor/models/florence2.py>
+- Molmo (insert after `<|endoftext|>` token): <gh-file:vllm/model_executor/models/molmo.py>
+
+### Handling prompt updates unrelated to multi-modal data
+
+{meth}`~vllm.multimodal.processing.BaseMultiModalProcessor._get_prompt_updates` assumes that each application of prompt update corresponds to one multi-modal item. If the HF processor performs additional processing regardless of how many multi-modal items there are, you should override {meth}`~vllm.multimodal.processing.BaseMultiModalProcessor._apply_hf_processor_tokens_only` so that the processed token inputs are consistent with the result of applying the HF processor on text inputs. This is because token inputs bypass the HF processor according to [our design](#mm-processing).
+
+Examples:
+
+- Chameleon (appends `sep_token`): <gh-file:vllm/model_executor/models/chameleon.py>
+- Fuyu (appends `boa_token`): <gh-file:vllm/model_executor/models/fuyu.py>
+- Molmo (applies chat template which is not defined elsewhere): <gh-file:vllm/model_executor/models/molmo.py>
+
+### Custom HF processor
+
+Some models don't define a HF processor class on HF Hub. In that case, you can define a custom HF processor that has the same call signature as HF processors and pass it to {meth}`~vllm.multimodal.processing.BaseMultiModalProcessor._call_hf_processor`.
+
+Examples:
+
+- DeepSeek-VL2: <gh-file:vllm/model_executor/models/deepseek_vl2.py>

+## Profile with NVIDIA Nsight Systems
+
+Nsight systems is an advanced tool that exposes more profiling details, such as register and shared memory usage, annotated code regions and low-level CUDA APIs and events.
+
+[Install nsight-systems](https://docs.nvidia.com/nsight-systems/InstallationGuide/index.html) using your package manager.
+The following block is an example for Ubuntu.
+
+```bash
+apt update
+apt install -y --no-install-recommends gnupg
+echo "deb http://developer.download.nvidia.com/devtools/repos/ubuntu$(source /etc/lsb-release; echo "$DISTRIB_RELEASE" | tr -d .)/$(dpkg --print-architecture) /" | tee /etc/apt/sources.list.d/nvidia-devtools.list
+apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub
+apt update
+apt install nsight-systems-cli
+```
+
+### Example commands and usage
+
+#### Offline Inference
+
+For basic usage, you can just append `nsys profile -o report.nsys-rep --trace-fork-before-exec=true --cuda-graph-trace=node` before any existing script you would run for offline inference.
+
+The following is an example using the `benchmarks/benchmark_latency.py` script:
+
+```bash
+nsys profile -o report.nsys-rep --trace-fork-before-exec=true --cuda-graph-trace=node python benchmarks/benchmark_latency.py --model meta-llama/Llama-3.1-8B-Instruct --num-iters-warmup 5 --num-iters 1 --batch-size 16 --input-len 512 --output-len 8
+```
+
+#### OpenAI Server
+
+To profile the server, you will want to prepend your `vllm serve` command with `nsys profile` just like for offline inference, however you must specify `--delay XX --duration YY` parameters according to the needs of your benchmark. After the duration time has been used up, the server will be killed.
+
+```bash
+# server
+nsys profile -o report.nsys-rep --trace-fork-before-exec=true --cuda-graph-trace=node --delay 30 --duration 60 vllm serve meta-llama/Llama-3.1-8B-Instruct
+
+# client
+python benchmarks/benchmark_serving.py --backend vllm --model meta-llama/Llama-3.1-8B-Instruct --num-prompts 1 --dataset-name random --random-input 1024 --random-output 512
+```
+
+In practice, you should set the `--duration` argument to a large value. Whenever you want the server to stop profiling, run:
+
+```
+nsys sessions list
+```
+
+to get the session id in the form of `profile-XXXXX`, then run:
+
+```
+nsys stop --session=profile-XXXXX
+```
+
+to manually kill the profiler and generate your `nsys-rep` report.
+
+#### Analysis
+
+You can view these profiles either as summaries in the CLI, using `nsys stats [profile-file]`, or in the GUI by installing Nsight [locally following the directions here](https://developer.nvidia.com/nsight-systems/get-started).

+## Profiling vLLM Python Code
+
+The Python standard library includes
+[cProfile](https://docs.python.org/3/library/profile.html) for profiling Python
+code. vLLM includes a couple of helpers that make it easy to apply it to a section of vLLM.
+Both the `vllm.utils.cprofile` and `vllm.utils.cprofile_context` functions can be
+used to profile a section of code.
+
+### Example usage - decorator
+
+The first helper is a Python decorator that can be used to profile a function.
+If a filename is specified, the profile will be saved to that file. If no filename is
+specified, profile data will be printed to stdout.
+
+```python
+import vllm.utils
+
+@vllm.utils.cprofile("expensive_function.prof")
+def expensive_function():
+    # some expensive code
+    pass
+```
+
+### Example Usage - context manager
+
+The second helper is a context manager that can be used to profile a block of
+code. Similar to the decorator, the filename is optional.
+
+```python
+import vllm.utils
+
+def another_function():
+    # more expensive code
+    pass
+
+with vllm.utils.cprofile_context("another_function.prof"):
+    another_function()
+```
+
+### Analyzing Profile Results
+
+There are multiple tools available that can help analyze the profile results.
+One example is [snakeviz](https://jiffyclub.github.io/snakeviz/).
+
+```bash
+pip install snakeviz
+snakeviz expensive_function.prof
+```

+# Production stack
+
+Deploying vLLM on Kubernetes is a scalable and efficient way to serve machine learning models. This guide walks you through deploying vLLM using the [vLLM production stack](https://github.com/vllm-project/production-stack). Born out of a Berkeley-UChicago collaboration, [vLLM production stack](https://github.com/vllm-project/production-stack) is an officially released, production-optimized codebase under the [vLLM project](https://github.com/vllm-project), designed for LLM deployment with:
+
+* **Upstream vLLM compatibility** – It wraps around upstream vLLM without modifying its code.
+* **Ease of use** – Simplified deployment via Helm charts and observability through Grafana dashboards.
+* **High performance** – Optimized for LLM workloads with features like multi-model support, model-aware and prefix-aware routing, fast vLLM bootstrapping, and KV cache offloading with [LMCache](https://github.com/LMCache/LMCache), among others.
+
+If you are new to Kubernetes, don't worry: in the vLLM production stack [repo](https://github.com/vllm-project/production-stack), we provide a step-by-step [guide](https://github.com/vllm-project/production-stack/blob/main/tutorials/00-install-kubernetes-env.md) and a [short video](https://www.youtube.com/watch?v=EsTJbQtzj0g) to set up everything and get started in **4 minutes**!
+
+## Pre-requisite
+
+Ensure that you have a running Kubernetes environment with GPU (you can follow [this tutorial](https://github.com/vllm-project/production-stack/blob/main/tutorials/00-install-kubernetes-env.md) to install a Kubernetes environment on a bare-medal GPU machine).
+
+## Deployment using vLLM production stack
+
+The standard vLLM production stack install uses a Helm chart. You can run this [bash script](https://github.com/vllm-project/production-stack/blob/main/tutorials/install-helm.sh) to install Helm on your GPU server.
+
+To install the vLLM production stack, run the following commands on your desktop:
+
+```bash
+sudo helm repo add vllm https://vllm-project.github.io/production-stack
+sudo helm install vllm vllm/vllm-stack -f tutorials/assets/values-01-minimal-example.yaml
+```
+
+This will instantiate a vLLM-production-stack-based deployment named `vllm` that runs a small LLM (Facebook opt-125M model).
+
+### Validate Installation
+
+Monitor the deployment status using:
+
+```bash
+sudo kubectl get pods
+```
+
+And you will see that pods for the `vllm` deployment will transit to `Running` state.
+
+```text
+NAME                                           READY   STATUS    RESTARTS   AGE
+vllm-deployment-router-859d8fb668-2x2b7        1/1     Running   0          2m38s
+vllm-opt125m-deployment-vllm-84dfc9bd7-vb9bs   1/1     Running   0          2m38s
+```
+
+**NOTE**: It may take some time for the containers to download the Docker images and LLM weights.
+
+### Send a Query to the Stack
+
+Forward the `vllm-router-service` port to the host machine:
+
+```bash
+sudo kubectl port-forward svc/vllm-router-service 30080:80
+```
+
+And then you can send out a query to the OpenAI-compatible API to check the available models:
+
+```bash
+curl -o- http://localhost:30080/models
+```
+
+Expected output:
+
+```json
+{
+  "object": "list",
+  "data": [
+    {
+      "id": "facebook/opt-125m",
+      "object": "model",
+      "created": 1737428424,
+      "owned_by": "vllm",
+      "root": null
+    }
+  ]
+}
+```
+
+To send an actual chatting request, you can issue a curl request to the OpenAI `/completion` endpoint:
+
+```bash
+curl -X POST http://localhost:30080/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "facebook/opt-125m",
+    "prompt": "Once upon a time,",
+    "max_tokens": 10
+  }'
+```
+
+Expected output:
+
+```json
+{
+  "id": "completion-id",
+  "object": "text_completion",
+  "created": 1737428424,
+  "model": "facebook/opt-125m",
+  "choices": [
+    {
+      "text": " there was a brave knight who...",
+      "index": 0,
+      "finish_reason": "length"
+    }
+  ]
+}
+```
+
+### Uninstall
+
+To remove the deployment, run:
+
+```bash
+sudo helm uninstall vllm
+```
+
+------
+
+### (Advanced) Configuring vLLM production stack
+
+The core vLLM production stack configuration is managed with YAML. Here is the example configuration used in the installation above:
+
+```yaml
+servingEngineSpec:
+  runtimeClassName: ""
+  modelSpec:
+  - name: "opt125m"
+    repository: "vllm/vllm-openai"
+    tag: "latest"
+    modelURL: "facebook/opt-125m"
+
+    replicaCount: 1
+
+    requestCPU: 6
+    requestMemory: "16Gi"
+    requestGPU: 1
+
+    pvcStorage: "10Gi"
+```
+
+In this YAML configuration:
+* **`modelSpec`** includes:
+  * `name`: A nickname that you prefer to call the model.
+  * `repository`: Docker repository of vLLM.
+  * `tag`: Docker image tag.
+  * `modelURL`: The LLM model that you want to use.
+* **`replicaCount`**: Number of replicas.
+* **`requestCPU` and `requestMemory`**: Specifies the CPU and memory resource requests for the pod.
+* **`requestGPU`**: Specifies the number of GPUs required.
+* **`pvcStorage`**: Allocates persistent storage for the model.
+
+**NOTE:** If you intend to set up two pods, please refer to this [YAML file](https://github.com/vllm-project/production-stack/blob/main/tutorials/assets/values-01-2pods-minimal-example.yaml).
+
+**NOTE:** vLLM production stack offers many more features (*e.g.* CPU offloading and a wide range of routing algorithms). Please check out these [examples and tutorials](https://github.com/vllm-project/production-stack/tree/main/tutorials) and our [repo](https://github.com/vllm-project/production-stack) for more details!

+## Deployment with CPUs
 
-## Deployment Steps
+:::{note}
+The use of CPUs here is for demonstration and testing purposes only and its performance will not be on par with GPUs.
+:::
+
+First, create a Kubernetes PVC and Secret for downloading and storing Hugging Face model:
+
+```bash
+cat <<EOF |kubectl apply -f -
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: vllm-models
+spec:
+  accessModes:
+    - ReadWriteOnce
+  volumeMode: Filesystem
+  resources:
+    requests:

+---
+apiVersion: v1
+kind: Secret
+metadata:
+  name: hf-token-secret
+type: Opaque
+data:
+  token: $(HF_TOKEN)
+```
+
+Next, start the vLLM server as a Kubernetes Deployment and Service:
+
+```bash
+cat <<EOF |kubectl apply -f -
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: vllm-server
+spec:
+  replicas: 1
+  selector:

+        args: [
+          "vllm serve meta-llama/Llama-3.2-1B-Instruct"
+        ]
+        env:
+        - name: HUGGING_FACE_HUB_TOKEN
+          valueFrom:
+            secretKeyRef:

+              key: token
+        ports:
+          - containerPort: 8000
+        volumeMounts:
+          - name: llama-storage

+  ports:
+  - protocol: TCP
+    port: 8000
+    targetPort: 8000
+  type: ClusterIP
+EOF
+```
+
+We can verify that the vLLM server has started successfully via the logs (this might take a couple of minutes to download the model):
+
+```console
+kubectl logs -l app.kubernetes.io/name=vllm
+...
+INFO:     Started server process [1]
+INFO:     Waiting for application startup.
+INFO:     Application startup complete.
+INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
+```
+
+## Deployment with GPUs
+
+**Pre-requisite**: Ensure that you have a running [Kubernetes cluster with GPUs](https://kubernetes.io/docs/tasks/manage-gpus/scheduling-gpus/).

    - HuggingFace also has its own logic to determine the config class to use. It will again use the `model_type` field to search for the class name in the transformers library; see [here](https://github.com/huggingface/transformers/tree/main/src/transformers/models) for the list of supported models. If the `model_type` is not found, HuggingFace will use the `auto_map` field from the config JSON file to determine the class name. Specifically, it is the `AutoConfig` field under `auto_map`. See [DeepSeek](https://huggingface.co/deepseek-ai/DeepSeek-V2.5/blob/main/config.json) for an example.
    - The `AutoConfig` field under `auto_map` points to a module path in the model's repository. To create the config class, HuggingFace will import the module and use the `from_pretrained` method to load the config class. This can generally cause arbitrary code execution, so it is only executed when `--trust_remote_code` is enabled.

+# Metrics
+
+Ensure the v1 LLM Engine exposes a superset of the metrics available in v0.
+
+## Objectives
+
+- Achieve parity of metrics between v0 and v1.
+- The priority use case is accessing these metrics via Prometheus as this is what we expect to be used in production environments.
+- Logging support - i.e. printing metrics to the info log - is provided for more ad-hoc testing, debugging, development, and exploratory use cases.
+
+## Background
+
+Metrics in vLLM can be categorized as follows:
+
+1. Server-level metrics: these are global metrics that track the state and performance of the LLM engine. These are typically exposed as Gauges or Counters in Prometheus.
+2. Request-level metrics: these are metrics that track the characteristics - e.g. size and timing - of individual requests. These are typically exposed as Histograms in Prometheus, and are often the SLO that an SRE monitoring vLLM will be tracking.
+
+The mental model is that the "Server-level Metrics" explain why the "Request-level Metrics" are what they are.
+
+### v0 Metrics
+
+In v0, the following metrics are exposed via a Prometheus-compatible `/metrics` endpoint using the `vllm:` prefix:
+
+- `vllm:num_requests_running` (Gauge)
+- `vllm:num_requests_swapped` (Gauge)
+- `vllm:num_requests_waiting` (Gauge)
+- `vllm:gpu_cache_usage_perc` (Gauge)
+- `vllm:cpu_cache_usage_perc` (Gauge)
+- `vllm:gpu_prefix_cache_hit_rate` (Gauge)
+- `vllm:cpu_prefix_cache_hit_rate` (Gauge)
+- `vllm:prompt_tokens_total` (Counter)
+- `vllm:generation_tokens_total` (Counter)
+- `vllm:request_success_total` (Counter)
+- `vllm:request_prompt_tokens` (Histogram)
+- `vllm:request_generation_tokens` (Histogram)
+- `vllm:time_to_first_token_seconds` (Histogram)
+- `vllm:time_per_output_token_seconds` (Histogram)
+- `vllm:e2e_request_latency_seconds` (Histogram)
+- `vllm:request_queue_time_seconds` (Histogram)
+- `vllm:request_inference_time_seconds` (Histogram)
+- `vllm:request_prefill_time_seconds` (Histogram)
+- `vllm:request_decode_time_seconds` (Histogram)
+- `vllm:request_max_num_generation_tokens` (Histogram)
+- `vllm:num_preemptions_total` (Counter)
+- `vllm:cache_config_info` (Gauge)
+- `vllm:lora_requests_info` (Gauge)
+- `vllm:tokens_total` (Counter)
+- `vllm:iteration_tokens_total` (Histogram)
+- `vllm:time_in_queue_requests` (Histogram)

+- `vllm:spec_decode_draft_acceptance_rate` (Gauge)
+- `vllm:spec_decode_efficiency` (Gauge)
+- `vllm:spec_decode_num_accepted_tokens_total` (Counter)
+- `vllm:spec_decode_num_draft_tokens_total` (Counter)
+- `vllm:spec_decode_num_emitted_tokens_total` (Counter)
+
+These are documented under [Inferencing and Serving -> Production Metrics](project:../../serving/metrics.md).
+
+### Grafana Dashboard
+
+vLLM also provides [a reference example](https://docs.vllm.ai/en/latest/getting_started/examples/prometheus_grafana.html) for how to collect and store these metrics using Prometheus and visualize them using a Grafana dashboard.
+
+The subset of metrics exposed in the Grafana dashboard gives us an indication of which metrics are especially important:
+
+- `vllm:e2e_request_latency_seconds_bucket` - End to end request latency measured in seconds
+- `vllm:prompt_tokens_total` - Prompt Tokens/Sec
+- `vllm:generation_tokens_total` - Generation Tokens/Sec
+- `vllm:time_per_output_token_seconds` - Inter token latency (Time Per Output Token, TPOT) in second.
+- `vllm:time_to_first_token_seconds` - Time to First Token (TTFT) latency in seconds.
+- `vllm:num_requests_running` (also, `_swapped` and `_waiting`) - Number of requests in RUNNING, WAITING, and SWAPPED state
+- `vllm:gpu_cache_usage_perc` - Percentage of used cache blocks by vLLM.
+- `vllm:request_prompt_tokens` - Request prompt length
+- `vllm:request_generation_tokens` - request generation length
+- `vllm:request_success_total` - Number of finished requests by their finish reason: either an EOS token was generated or the max sequence length was reached
+- `vllm:request_queue_time_seconds` - Queue Time
+- `vllm:request_prefill_time_seconds` - Requests Prefill Time
+- `vllm:request_decode_time_seconds` - Requests Decode Time
+- `vllm:request_max_num_generation_tokens` - Max Generation Token in Sequence Group
+
+See [the PR which added this Dashboard](gh-pr:2316) for interesting and useful background on the choices made here.
+
+### Prometheus Client Library
+
+Prometheus support was initially added [using the aioprometheus library](gh-pr:1890), but a switch was made quickly to [prometheus_client](gh-pr:2730). The rationale is discussed in both linked PRs.
+
+### Multi-process Mode
+
+In v0, metrics are collected in the engine core process and we use multi-process mode to make them available in the API server process. See <gh-pr:7279>.
+
+### Built in Python/Process Metrics
+
+The following metrics are supported by default by `prometheus_client`, but the are not exposed with multiprocess mode is used:
+
+- `python_gc_objects_collected_total`
+- `python_gc_objects_uncollectable_total`
+- `python_gc_collections_total`
+- `python_info`
+- `process_virtual_memory_bytes`
+- `process_resident_memory_bytes`
+- `process_start_time_seconds`
+- `process_cpu_seconds_total`
+- `process_open_fds`
+- `process_max_fds`
+
+This is relevant because if we move away from multiprocess mode in v1,
+we get these back. However, it's questionable how relevant these are
+if they don't aggregate these stats for all processes that make up a
+vLLM instance.

+
+### Metrics Collection
+
+In v1, we wish to move computation and overhead out of the engine core
+process to minimize the time between each forward pass.
+
+The overall idea of V1 EngineCore design is:
+- EngineCore is the inner loop. Performance is most critical here
+- AsyncLLM is the outer loop. This is overlapped with GPU execution
+  (ideally), so this is where any "overheads" should be if
+  possible. So AsyncLLM.output_handler_loop is the ideal place for the
+  metrics bookkeeping if possible.
+
+We will achieve this by collecting metrics in the frontend API server,
+and base these metrics on information we can glean from the
+`EngineCoreOutputs` returned by the engine core process to the
+frontend.
+
+### Interval Calculations
+
+Many of our metrics are the time interval between various events in
+the processing of a request. It is best practice to use timestamps
+based on "monotonic time" (`time.monotonic()`) rather than "wall-clock
+time" (`time.time()`) to calculate intervals as the former is
+unaffected by system clock changes (e.g. from NTP).
+
+It's also important to note that monotonic clocks differ between
+processes - each process has its own reference. point. So it is
+meaningless to compare monotonic timestamps from different processes.
+
+Therefore, in order to calculate an interval, we must compare two
+monotonic timestamps from the same process.
+
+### Scheduler Stats
+
+The engine core process will collect some key statistics from the
+scheduler - e.g. the number of requests that were scheduled or waiting
+after the last scheduler pass - and include those statistics in
+`EngineCoreOutputs`.
+
+### Engine Core Events
+
+The engine core will also record the timestamp of certain per-request
+events so that the frontend can calculate the interval between these
+events.
+
+The events are:
+
+- `QUEUED` - when the request was received by the engine core and
+  added to the scheduler queue.
+- `SCHEDULED` - when the request was first scheduled for execution.
+- `PREEMPTED` - the request has been put back in the waiting queue
+  in order to make room for other requests to complete. It will be
+  re-scheduled in future and re-start its prefill phase.
+- `NEW_TOKENS` - when the output included in `EngineCoreOutput` was
+  generated. Since this is common to all requests in a given
+  iteration, we use a single timestamp on `EngineCoreOutputs` to
+  record this event.
+
+And the calculated intervals are:
+
+- Queue interval - between `QUEUED` and most recent `SCHEDULED`.
+- Prefill interval - between most recent `SCHEDULED` and the subsequent
+  first `NEW_TOKENS`.
+- Decode interval - between first (after the most recent `SCHEDULED`) and
+  last `NEW_TOKENS`.
+- Inference interval - between most recent `SCHEDULED` and last `NEW_TOKENS`.
+- Inter-token interval - between successive `NEW_TOKENS`.
+
+Put another way:
+
+:::{image} /assets/design/v1/metrics/intervals-1.png
+:alt: Interval calculations - common case
+:::
+
+We explored the possibility of having the frontend calculate these
+intervals using the timing of events visible by the frontend. However,
+the frontend does not have visibility into the timing of the `QUEUED`
+and `SCHEDULED` events and, since we need to calculate intervals based
+on monotonic timestamps from the same process ... we need the engine
+core to record timestamps for all of these events.
+
+#### Interval Calculations vs Preemptions
+
+When a preemption occurs during decode, since any already generated
+tokens are reused, we consider the preemption as affecting the
+inter-token, decode, and inference intervals.
+
+:::{image} /assets/design/v1/metrics/intervals-2.png
+:alt: Interval calculations - preempted decode
+:::
+
+When a preemption occurs during prefill (assuming such an event
+is possible), we consider the preemption as affecting the
+time-to-first-token and prefill intervals.
+
+:::{image} /assets/design/v1/metrics/intervals-3.png
+:alt: Interval calculations - preempted prefill
+:::
+
+### Frontend Stats Collection
+
+As the frontend processes a single `EngineCoreOutputs` - i.e. the
+output from a single engine core iteration - it collects various
+statistics relating to that iteration:
+
+- The total number of new tokens generated in this iteration.
+- The total number of prompt tokens processed by the prefills that
+  completed in this iteration.
+- The queue intervals for any requests that were scheduled in this
+  iteration.
+- The prefill intervals for any requests that completed prefill in
+  this iteration.
+- The inter-token intervals (Time Per Output Token, TPOT), for all
+  requests included in this iteration.
+- The Time-To-First-Token (TTFT) for any requests that completed
+  prefill in this iteration. However, we calculate this interval
+  relative to when the request was first received by the frontend
+  (`arrival_time`) in order to account for input processing time.
+
+For any requests that were completed in a given iteration, we also
+record:
+
+- The inference and decode intervals - relative to the scheduled and
+  first token events, as described above.
+- End-to-end latency - the interval between frontend `arrival_time`
+  and the frontend receiving the final token.
+
+### Metrics Publishing - Logging
+
+The `LoggingStatLogger` metrics publisher outputs a log `INFO` message
+every 5 seconds with some key metrics:
+
+- The current number of running/waiting requests
+- The current GPU cache usage
+- The number of prompt tokens processed per second over the past 5
+  seconds
+- The number of new tokens generated per second over the past 5
+  seconds
+- The prefix cache hit rate over the most recent 1k kv-cache block queries
+
+### Metrics Publishing - Prometheus
+
+The `PrometheusStatLogger` metrics publisher makes the metrics
+available via a `/metrics` HTTP endpoint in a Prometheus-compatible
+format. A Prometheus instance can then be configured to poll this
+endpoint (e.g. every second) and record the values in its time-series
+database. Prometheus is often used via Grafana, allowing these metrics
+to be graphed over time.
+
+Prometheus supports the following metric types:
+
+- Counter: a value that will increase over time, never reducing, and
+  generally reset to zero when the vLLM instance restarts. For
+  example, the number of tokens generated over the lifetime of the
+  instance.
+- Gauge: a value that goes up and down, for example the number of
+  requests currently scheduled for execution.
+- Histogram: a count of metric samples, recorded in buckets. For
+  example, the number of requests whose TTFT was <1ms, <5ms, <10ms,
+  <20ms, and so on.
+
+Prometheus metrics can also be labelled, allowing metrics to be
+combined according to matching labels. In vLLM, we add a `model_name`
+label to every metric which includes the name of the model served by
+that instance.

+```
+
+Note - the choice of histogram buckets to be most useful to users
+across a broad set of use cases is not straightforward and will
+require refinement over time.
+
+### Cache Config Info
+
+`prometheus_client` has support for [Info
+metrics](https://prometheus.github.io/client_python/instrumenting/info/)
+which are equivalent to a `Gauge` whose value is permanently set to 1,
+but exposes interesting key/value pair information via labels. This is
+used for information about an instance that does not change - so it
+only needs to be observed at startup - and allows comparing across
+instances in Prometheus.
+
+We use this concept for the `vllm:cache_config_info` metric:
+
+```
+# HELP vllm:cache_config_info Information of the LLMEngine CacheConfig
+# TYPE vllm:cache_config_info gauge
+vllm:cache_config_info{block_size="16",cache_dtype="auto",calculate_kv_scales="False",cpu_offload_gb="0",enable_prefix_caching="False",gpu_memory_utilization="0.9",...} 1.0
+
+```
+
+However, `prometheus_client` has [never supported Info metrics in
+multiprocessing
+mode](https://github.com/prometheus/client_python/pull/300) - for
+[unclear
+reasons](gh-pr:7279#discussion_r1710417152). We
+simply use a `Gauge` metric set to 1 and
+`multiprocess_mode="mostrecent"` instead.
+
+### LoRA Metrics
+
+The `vllm:lora_requests_info` `Gauge` is somewhat similar, except the
+value is the current wall-clock time, and is updated every iteration.
+
+The label names used are:
+
+- `running_lora_adapters`: a per-adapter count of the number requests
+  running using that adapter, formatted as a comma-separated string.
+- `waiting_lora_adapters`: similar, except counting requests that are
+  waiting to be scheduled.
+- `max_lora` - the static "max number of LoRAs in a single batch."
+  configuration.
+
+Encoding a running/waiting counts for multiple adapters in a
+comma-separated string seems quite misguided - we could use labels to
+distinguish between per-adapter counts. This should be revisited.
+
+Note that `multiprocess_mode="livemostrecent"` is used - the most
+recent metric is used, but only from currently running processes.
+
+This was added in
+<gh-pr:9477> and there is
+[at least one known
+user](https://github.com/kubernetes-sigs/gateway-api-inference-extension/pull/54). If
+we revisit this design and deprecate the old metric, we should reduce
+the need for a significant deprecation period by making the change in
+v0 also and asking this project to move to the new metric.
+
+### Prefix Cache metrics
+
+The discussion in <gh-issue:10582> about adding prefix cache metrics yielded
+some interesting points which may be relevant to how we approach
+future metrics.
+
+Every time the prefix cache is queried, we record the number of blocks
+queried and the number of queried blocks present in the cache
+(i.e. hits).
+
+However, the metric of interest is the hit rate - i.e. the number of
+hits per query.
+
+In the case of logging, we expect the user is best served by
+calculating the hit rate over a fixed number of the most recent
+queries (the interval is fixed to 1k most recent queries for now).
+
+In the case of Prometheus though, we should take advantage of the
+time-series nature of Prometheus and allow the user to calculate the
+hit rate over an interval of their choosing. For example, a PromQL
+query to calculate the hit interval of the past 5 minutes:
+
+```text
+rate(cache_query_hit[5m]) / rate(cache_query_total[5m])
+```
+
+To achieve this, we should record the queries and hits as counters in
+Prometheus, rather than recording the hit rate as a gauge.
+
+## Deprecated Metrics
+
+### How To Deprecate
+
+Deprecating metrics shouldn't be taken lightly. Users may not notice a
+metric has been deprecated, and may be quite inconvenienced when it is
+suddenly (from their perspective) when it is removed, even if there is
+an equivalent metric for them to use.
+
+As an example, see how `vllm:avg_prompt_throughput_toks_per_s` was
+[deprecated](gh-pr:2764) (with a
+comment in the code),
+[removed](gh-pr:12383), and then
+[noticed by a
+user](gh-issue:13218).
+
+In general:
+
+1) We should be cautious about deprecating metrics, especially since
+   it can be hard to predict the user impact.
+2) We should include a prominent deprecation notice in the help string
+   that is included in the `/metrics' output.
+3) We should list deprecated metrics in user-facing documentation and
+   release notes.
+4) We should consider hiding deprecated metrics behind a CLI argument
+   in order to give administrators [an escape
+   hatch](https://kubernetes.io/docs/concepts/cluster-administration/system-metrics/#show-hidden-metrics)
+   for some time before deleting them.
+
+### Unimplemented - `vllm:tokens_total`
+
+Added by <gh-pr:4464>, but apparently never implemented. This can just be
+removed.
+
+### Duplicated - Queue Time
+
+The `vllm:time_in_queue_requests` Histogram metric was added by
+<gh-pr:9659> and its calculation is:
+
+```
+    self.metrics.first_scheduled_time = now
+    self.metrics.time_in_queue = now - self.metrics.arrival_time
+```
+
+Two weeks later, <gh-pr:4464> added `vllm:request_queue_time_seconds` leaving
+us with:
+
+```
+if seq_group.is_finished():
+    if (seq_group.metrics.first_scheduled_time is not None and
+            seq_group.metrics.first_token_time is not None):
+        time_queue_requests.append(
+            seq_group.metrics.first_scheduled_time -
+            seq_group.metrics.arrival_time)
+    ...
+    if seq_group.metrics.time_in_queue is not None:
+        time_in_queue_requests.append(
+            seq_group.metrics.time_in_queue)
+```
+
+This seems duplicative, and one of them should be removed. The latter
+is used by the Grafana dashboard, so we should deprecate or remove the
+former from v0.
+
+### Prefix Cache Hit Rate
+
+See above - we now expose 'queries' and 'hits' counters rather than a
+'hit rate' gauge.
+
+### KV Cache Offloading
+
+Two v0 metrics relate to a "swapped" preemption mode that is no
+longer relevant in v1:
+
+- `vllm:num_requests_swapped`
+- `vllm:cpu_cache_usage_perc`
+
+In this mode, when a request is preempted (e.g. to make room in KV
+cache to complete other requests), we swap kv cache blocks out to CPU
+memory. This is also known as "KV cache offloading" and is configured
+with `--swap-space` and `--preemption-mode`.
+
+In v0, [vLLM has long supported beam
+search](gh-issue:6226). The
+SequenceGroup encapsulated the idea of N Sequences which
+all shared the same prompt kv blocks. This enabled KV cache block
+sharing between requests, and copy-on-write to do branching. CPU
+swapping was intended for these beam search like cases.
+
+Later, the concept of prefix caching was introduced, which allowed KV
+cache blocks to be shared implicitly. This proved to be a better
+option than CPU swapping since blocks can be evicted slowly on demand
+and the part of the prompt that was evicted can be recomputed.
+
+SequenceGroup was removed in V1, although a replacement will be
+required for "parallel sampling" (`n>1`). [Beam search was moved out of
+the core (in
+V0)](gh-issue:8306). There was a
+lot of complex code for a very uncommon feature.
+
+In V1, with prefix caching being better (zero over head) and therefore
+on by default, the preemption and recompute strategy should work
+better.
+
+## Future Work
+
+### Parallel Sampling
+
+Some v0 metrics are only relevant in the context of "parallel
+sampling". This is where the `n` parameter in a request is used to
+request multiple completions from the same prompt.
+
+As part of adding parallel sampling support in <gh-pr:10980> we should
+also add these metrics.
+
+- `vllm:request_params_n` (Histogram)
+
+Observes the value of the 'n' parameter of every finished request.
+
+- `vllm:request_max_num_generation_tokens` (Histogram)
+
+Observes the maximum output length of all sequences in every finished
+sequence group. In the absence of parallel sampling, this is
+equivalent to `vllm:request_generation_tokens`.
+
+### Speculative Decoding
+
+Some v0 metrics are specific to "speculative decoding". This is where
+we generate candidate tokens using a faster, approximate method or
+model and then validate those tokens with the larger model.
+
+- `vllm:spec_decode_draft_acceptance_rate` (Gauge)
+- `vllm:spec_decode_efficiency` (Gauge)
+- `vllm:spec_decode_num_accepted_tokens_total` (Counter)
+- `vllm:spec_decode_num_draft_tokens_total` (Counter)
+- `vllm:spec_decode_num_emitted_tokens_total` (Counter)
+
+There is a PR under review (<gh-pr:12193>) to add "prompt lookup (ngram)"
+seculative decoding to v1. Other techniques will follow. We should
+revisit the v0 metrics in this context.
+
+Note - we should probably expose acceptance rate as separate accepted
+and draft counters, like we do for prefix caching hit rate. Efficiency
+likely also needs similar treatment.
+
+### Autoscaling and Load-balancing
+
+A common use case for our metrics is to support automated scaling of
+vLLM instances.
+
+For related discussion from the [Kubernetes Serving Working
+Group](https://github.com/kubernetes/community/tree/master/wg-serving),
+see:
+
+- [Standardizing Large Model Server Metrics in
+  Kubernetes](https://docs.google.com/document/d/1SpSp1E6moa4HSrJnS4x3NpLuj88sMXr2tbofKlzTZpk)
+- [Benchmarking LLM Workloads for Performance Evaluation and
+  Autoscaling in
+  Kubernetes](https://docs.google.com/document/d/1k4Q4X14hW4vftElIuYGDu5KDe2LtV1XammoG-Xi3bbQ)
+- [Inference
+  Perf](https://github.com/kubernetes-sigs/wg-serving/tree/main/proposals/013-inference-perf)
+- <gh-issue:5041> and <gh-pr:12726>.
+  
+This is a non-trivial topic. Consider this comment from Rob:
+
+> I think this metric should focus on trying to estimate what the max
+> concurrency that will cause the average request length > queries per
+> second ... since this is really what will "saturate" the server.
+
+A clear goal is that we should expose the metrics required to detect
+this saturation point, so administrators can implement auto-scaling
+rules based on those. However, in order to do so, we need to have a
+clear view on how an administrator (and automated monitoring system)
+should judge an instance as approaching saturation:
+
+> To identify, what is the saturation point for model server compute
+> (the inflection point where we cannot get more throughput with a
+> higher request rate, but start to incur additional latency) so we
+> can autoscale effectively?
+
+### Metric Naming
+
+Our approach to naming metrics probably deserves to be revisited:
+
+1. The use of colons in metric names seems contrary to ["colons are
+   reserved for user defined recording
+   rules"](https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels)
+2. Most of our metrics follow the convention of ending with units, but
+   not all do.
+3. Some of our metric names end with `_total`:
+
+```
+If there is a suffix of `_total` on the metric name, it will be removed. When
+exposing the time series for counter, a `_total` suffix will be added. This is
+for compatibility between OpenMetrics and the Prometheus text format, as OpenMetrics
+requires the `_total` suffix.
+```
+
+### Adding More Metrics
+
+There is no shortage of ideas for new metrics:
+
+- Examples from other projects like
+  [TGI](https://github.com/IBM/text-generation-inference?tab=readme-ov-file#metrics)
+- Proposals arising from specific use cases, like the Kubernetes
+  auto-scaling topic above
+- Proposals that might arise out of standardisation efforts like
+  [OpenTelemetry Semantic Conventions for Gen
+  AI](https://github.com/open-telemetry/semantic-conventions/tree/main/docs/gen-ai).
+
+We should be cautious in our approach to adding new metrics. While
+metrics are often relatively straightforward to add:
+
+1. They can be difficult to remove - see the section on deprecation
+   above.
+2. They can have a meaningful performance impact when enabled. And
+   metrics are usually of very limited use unless they can be enabled
+   by default and in production.
+3. They have an impact on development and maintenance of the
+   project. Every metric added to v0 has made this v1 effort more
+   time-consuming, and perhaps not all metrics justify this ongoing
+   investment in their maintenance.
+
+## Tracing - OpenTelemetry
+
+Metrics provide an aggregated view over time of the system's
+performance and health. Tracing, on the other hand, tracks individual
+requests as they move through different services and components. Both
+fall under the more general heading of "Observability".
+
+v0 has support for OpenTelemetry tracing:
+
+- Added by <gh-pr:4687>
+- Configured with `--oltp-traces-endpoint` and
+  `--collect-detailed-traces`
+- [OpenTelemetry blog
+  post](https://opentelemetry.io/blog/2024/llm-observability/)
+- [User-facing
+  docs](https://docs.vllm.ai/en/latest/getting_started/examples/opentelemetry.html)
+- [Blog
+  post](https://medium.com/@ronen.schaffer/follow-the-trail-supercharging-vllm-with-opentelemetry-distributed-tracing-aa655229b46f)
+- [IBM product
+  docs](https://www.ibm.com/docs/en/instana-observability/current?topic=mgaa-monitoring-large-language-models-llms-vllm-public-preview)
+  
+OpenTelemetry has a [Gen AI Working
+Group](https://github.com/open-telemetry/community/blob/main/projects/gen-ai.md).
+
+Since metrics is a big enough topic on its own, we are going to tackle
+the topic of tracing in v1 separately.
+
+### OpenTelemetry Model Forward vs Execute Time
+
+In v0, we have the following two metrics:
+
+- `vllm:model_forward_time_milliseconds` (Histogram) - The time spent
+  in the model forward pass when this request was in the batch.
+- `vllm:model_execute_time_milliseconds` (Histogram) - The time spent
+  in the model execute function. This will include model forward,
+  block/sync across workers, cpu-gpu sync time and sampling time.
+
+These metrics are only enabled when OpenTelemetry tracing is enabled
+and if `--collect-detailed-traces=all/model/worker` is used. The
+documentation for this option states:
+
+> collect detailed traces for the specified "modules. This involves
+> use of possibly costly and or blocking operations and hence might
+> have a performance impact.
+
+The metrics were added by <gh-pr:7089> and who up in an OpenTelemetry trace
+as:
+
+```
+-> gen_ai.latency.time_in_scheduler: Double(0.017550230026245117)
+-> gen_ai.latency.time_in_model_forward: Double(3.151565277099609)
+-> gen_ai.latency.time_in_model_execute: Double(3.6468167304992676)
+```
+
+We already have `inference_time` and `decode_time` metrics, so the
+question is whether there are sufficiently common use cases for the
+higher-resolution timings to justify the overhead.
+
+Since we are going to treat the question of OpenTelemetry support
+separately, we will include these particular metrics under that topic.

+# vLLM's `torch.compile` integration
+
+In vLLM's V1 architecture, `torch.compile` is enabled by default and is a critical part of the framework. This document gives a simple walk-through example to show how to understand the `torch.compile` usage.
+
+Throughout the example, we will run a common Llama model using v1, and turn on debug level logging to show all the details. The command to be used is `VLLM_USE_V1=1 VLLM_LOGGING_LEVEL=DEBUG vllm serve meta-llama/Llama-3.2-1B`.
+
+## Compilation Cache
+
+In the very verbose logs, we can see:
+
+```
+INFO 03-07 03:06:55 [backends.py:409] Using cache directory: ~/.cache/vllm/torch_compile_cache/1517964802/rank_0_0 for vLLM's torch.compile
+```
+
+vLLM will take all the available factors into consideration, and decide a directory to store all the compilation artifact. This means, you can directly copy the whole `~/.cache/vllm/torch_compile_cache` directory in your deployment scenario to save a great amount of compilation time, and hence accelerating the starting time of the vLLM instance.
+
+The factors considered include:
+
+- All the related configs (see the `compute_hash` functions in the [config.py](gh-file:vllm/config.py))
+- PyTorch configs (see the `compute_hash` functions in the [compiler_interface.py](gh-file:vllm/compilation/compiler_interface.py))
+- The model's forward function and the relevant functions called by the forward function (see below)
+
+With all these factors taken into consideration, usually we can guarantee that the cache is safe to use, and will not cause any unexpected behavior. Therefore, the cache is enabled by default. If you want to debug the compilation process, or if you suspect the cache is causing some issues, you can disable it by setting the environment variable `VLLM_DISABLE_COMPILE_CACHE=1`.
+
+A unique aspect of vLLM's `torch.compile` integration, is that we guarantee all the compilation finishes before we serve any requests. No requests will trigger new compilations. Otherwise, the engine would be blocked on that request, and the response time will have unexpected spikes.

+```
+
+This is about the Python code compilation, i.e. graph capture by Dynamo. It tries to trace the function with code `xxx/vllm/model_executor/models/llama.py:339`, which is the `forward` function of the model we compile. During the forward pass, there are also other functions called and inlined by Dynamo, as shown by the logs, including some PyTorch functions from `xxx/torch/nn/modules/module.py` (used by PyTorch `nn.Module`, because module attribute access will trigger a function call), some communication / attention / activation functions from vLLM. All the traced files will be considered when we decide the cache directory to use. This way, any code change in the above files will trigger compilation cache miss, and therefore recompilation.
+
+The result of the Dynamo compilation, is a new function stored in `~/.cache/vllm/torch_compile_cache/1517964802/rank_0_0/transformed_code.py`. Usually, this function unpacks tensors from the module, and then pass it to the traced computation graph. The computation graph is stored in `~/.cache/vllm/torch_compile_cache/1517964802/rank_0_0/computation_graph.py`.
+
+## Computation Graph Processing
+
+The computation graph has shape annotations for every tensor. The inputs are input ids, position ids, weights and buffers from the model, and the outputs are the final hidden states. Note that lm head projection and sampling operations are not considered in the graph.
+
+Most of the inputs to the computation graph has static shape, since they are model weights and buffers, and will not change during the lifetime of the model. Only the input ids and position ids have symbolic shapes, i.e. the shape can change from batch to batch. However, they will share the same symbolic shapes. That is to say, the only changing size to the computation graph, is the batch size (number of tokens processed in the current forward pass).
+
+The attention operation is complicated, and it needs to interact with kv caches, with complicated shapes. Fortunately, the output of the attention operation just share the same shape as the input query of the attention operation. Therefore, we wrap the whole attention operation into a PyTorch custom op `torch.ops.vllm.unified_attention_with_output`, so that Dynamo will not try to inspect any of the internal operations. This way, although attention operation is complicated, we can still capture the model's computation graph as a full-graph, from Dynamo's perspective.
+
+The computation graph is further split into pieces, by the `splitting_ops` (usually this is the attention operation). Therefore, in the `~/.cache/vllm/torch_compile_cache/1517964802/rank_0_0/computation_graph.py` file, we can see lots of submodules, each submodule is a piece of graph after splitting:
+
+- Attention operation itself is a submodule.
+- The part of computation graph, from one attention operation to the next attention operation, is a submodule.
+
+Every submodule can be identified by its index, and will be processed individually.
+
+## Computation Graph Compilation
+
+In the very verbose logs, we can also see:
+
+```

+```
+
+This means the first piece of computation graph (with shape `None` for symbolic shape) is compiled by Inductor (with a key `fpegyiq3v3wzjzphd45wkflpabggdbjpylgr7tta4hj6uplstsiw`). The compiled kernel is stored in  `~/.cache/vllm/torch_compile_cache/1517964802/rank_0_0/inductor_cache/iw/ciwzrk3ittdqatuzwonnajywvno3llvjcs2vfdldzwzozn3zi3iy.py`. You can open the file to see what is the code Inductor finally runs.
+
+One more detail: you can see that the 1-th graph and the 15-th graph have the same key, while the 0-th graph and the 16-th graph are different. This is expected, since we split the graph by the attention op, we get 3 unique subgraphs:
+
+- the first layer before attention
+- every middle layer, from one attention operation to the next attention operation
+- the final layer after attention
+
+If we already have the cache directory (e.g. run the same code for the second time), we will see the following logs:
+
+```
+DEBUG 03-07 04:00:45 [backends.py:86] Directly load the 0-th graph for shape None from inductor via handle ('fpegyiq3v3wzjzphd45wkflpabggdbjpylgr7tta4hj6uplstsiw', '~/.cache/vllm/torch_compile_cache/1517964802/rank_0_0/inductor_cache/iw/ciwzrk3ittdqatuzwonnajywvno3llvjcs2vfdldzwzozn3zi3iy.py')
+```
+
+This time, Inductor compilation is completely bypassed, and we will load from disk to read the compilation artifact we get from the last time.
+
+The above example just uses Inductor to compile for a general shape (i.e. symbolic shape). We can also use Inductor to compile for some of the specific shapes, for example:
+
+`VLLM_USE_V1=1 vllm serve meta-llama/Llama-3.2-1B --compilation_config "{'compile_sizes': [1, 2, 4, 8]}"`
+
+Then it will also compile a specific kernel just for batch size `1, 2, 4, 8`. At this time, all of the shapes in the computation graph are static and known, and we will turn on auto-tuning to tune for max performance. This can be slow when you run it for the first time, but the next time you run it, we can directly bypass the tuning and run the tuned kernel.
+
+When all the shapes are known, `torch.compile` can compare different configs, and often find some better configs to run the kernel. For example, we can see the following log:
+
+```

+SingleProcess AUTOTUNE benchmarking takes 2.0428 seconds and 7.5727 seconds precompiling
+```
+
+It means, for a matrix multiplication with shape `8x2048x3072`, `torch.compile` tries triton template with various configs, and it is much faster than the default code (which dispatches to cublas library).
+
+Unfortunately, because auto-tuning takes quite a long time (from seconds to minutes, depending on the model size and the batch size), even though it can be cached for later use, for the sake of user-friendliness, we turn it off by default. If you want to have max performance, it is recommended to try it, by compiling specific shapes.
+
+## Cudagraph Capture
+
+vLLM's V1 architecture uses piecewise cudagraph. The full computation graph is split as mentioned above, and we only capture the cudagraph for the piece of graph between attention operations (including the first graph before any attention operation, and the last graph after all the attention operation). This is based on a common observation: computation between attentions are usually token-wise and easy to deal with for cudagraph; while the attention operation is non-trival to be cudagraph compatible. Thus, by running the attention operation in eager mode while the rest operations in cudagraph, we keep the flexibility of the attention operation.
+
+The piecewise cudagraph also has fine-grained memory management. The purpose is to only exclude the attention kernel from cudagraph, while keeping all the rest modules and the memory allocation operations in the cudagraph. This is why the attention operation in V1 has the output tensor as the input of the attention.
+
+The cudagraphs are captured and managed by the compiler backend, and replayed when the batch size has corresponding cudagraph captured. The caller of the model (model runner) only needs to make sure it manages the input buffers correctly. All of the intermediate buffers are managed automatically by the compiler backend.
+
+By default, vLLM will try to determine a set of sizes to capture cudagraph. You can also override it using the config `cudagraph_capture_sizes`:
+
+`VLLM_USE_V1=1 vllm serve meta-llama/Llama-3.2-1B --compilation_config "{'cudagraph_capture_sizes': [1, 2, 4, 8]}"`
+
+Then it will only capture cudagraph for the specified sizes. It can be useful to have fine-grained control over the cudagraph capture.

+# AMD QUARK
+
+Quantization can effectively reduce memory and bandwidth usage, accelerate computation and improve
+throughput while with minimal accuracy loss. vLLM can leverage [Quark](https://quark.docs.amd.com/latest/),
+the flexible and powerful quantization toolkit, to produce performant quantized models to run on AMD GPUs. Quark has specialized support for quantizing large language models with weight,
+activation and kv-cache quantization and cutting-edge quantization algorithms like
+AWQ, GPTQ, Rotation and SmoothQuant.
+
+## Quark Installation
+
+Before quantizing models, you need to install Quark. The latest release of Quark can be installed with pip:
+
+```console
+pip install amd-quark
+```
+
+You can refer to [Quark installation guide](https://quark.docs.amd.com/latest/install.html)
+for more installation details.
+
+## Quantization Process
+
+After installing Quark, we will use an example to illustrate how to use Quark.  
+The Quark quantization process can be listed for 5 steps as below:
+
+1. Load the model
+2. Prepare the calibration dataloader
+3. Set the quantization configuration
+4. Quantize the model and export
+5. Evaluation in vLLM
+
+### 1. Load the Model
+
+Quark uses [Transformers](https://huggingface.co/docs/transformers/en/index)
+to fetch model and tokenizer.
+
+```python
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+MODEL_ID = "meta-llama/Llama-2-70b-chat-hf"
+MAX_SEQ_LEN = 512
+
+model = AutoModelForCausalLM.from_pretrained(
+    MODEL_ID, device_map="auto", torch_dtype="auto",
+)
+model.eval()
+
+tokenizer = AutoTokenizer.from_pretrained(MODEL_ID, model_max_length=MAX_SEQ_LEN)
+tokenizer.pad_token = tokenizer.eos_token
+```
+
+### 2. Prepare the Calibration Dataloader
+
+Quark uses the [PyTorch Dataloader](https://pytorch.org/tutorials/beginner/basics/data_tutorial.html)
+to load calibration data. For more details about how to use calibration datasets efficiently, please refer
+to [Adding Calibration Datasets](https://quark.docs.amd.com/latest/pytorch/calibration_datasets.html).
+
+```python
+from datasets import load_dataset
+from torch.utils.data import DataLoader
+
+BATCH_SIZE = 1
+NUM_CALIBRATION_DATA = 512
+

+calib_dataloader = DataLoader(tokenized_outputs['input_ids'],
+    batch_size=BATCH_SIZE, drop_last=True)
+```
+
+### 3. Set the Quantization Configuration
+
+We need to set the quantization configuration, you can check
+[quark config guide](https://quark.docs.amd.com/latest/pytorch/user_guide_config_description.html)
+for further details. Here we use FP8 per-tensor quantization on weight, activation,
+kv-cache and the quantization algorithm is AutoSmoothQuant.
+
+:::{note}
+Note the quantization algorithm needs a JSON config file and the config file is located in
+[Quark Pytorch examples](https://quark.docs.amd.com/latest/pytorch/pytorch_examples.html),
+under the directory `examples/torch/language_modeling/llm_ptq/models`. For example,
+AutoSmoothQuant config file for Llama is
+`examples/torch/language_modeling/llm_ptq/models/llama/autosmoothquant_config.json`.
+:::
+
+```python
+from quark.torch.quantization import (Config, QuantizationConfig,
+                                     FP8E4M3PerTensorSpec,
+                                     load_quant_algo_config_from_file)
+
+# Define fp8/per-tensor/static spec.
+FP8_PER_TENSOR_SPEC = FP8E4M3PerTensorSpec(observer_method="min_max",
+    is_dynamic=False).to_quantization_spec()
+
+# Define global quantization config, input tensors and weight apply FP8_PER_TENSOR_SPEC.
+global_quant_config = QuantizationConfig(input_tensors=FP8_PER_TENSOR_SPEC,
+    weight=FP8_PER_TENSOR_SPEC)
+
+# Define quantization config for kv-cache layers, output tensors apply FP8_PER_TENSOR_SPEC.
+KV_CACHE_SPEC = FP8_PER_TENSOR_SPEC
+kv_cache_layer_names_for_llama = ["*k_proj", "*v_proj"]
+kv_cache_quant_config = {name :
+    QuantizationConfig(input_tensors=global_quant_config.input_tensors,
+                       weight=global_quant_config.weight,
+                       output_tensors=KV_CACHE_SPEC)
+    for name in kv_cache_layer_names_for_llama}
+layer_quant_config = kv_cache_quant_config.copy()
+
+# Define algorithm config by config file.
+LLAMA_AUTOSMOOTHQUANT_CONFIG_FILE =
+    'examples/torch/language_modeling/llm_ptq/models/llama/autosmoothquant_config.json'
+algo_config = load_quant_algo_config_from_file(LLAMA_AUTOSMOOTHQUANT_CONFIG_FILE)
+
+EXCLUDE_LAYERS = ["lm_head"]
+quant_config = Config(
+    global_quant_config=global_quant_config,
+    layer_quant_config=layer_quant_config,
+    kv_cache_quant_config=kv_cache_quant_config,
+    exclude=EXCLUDE_LAYERS,
+    algo_config=algo_config)
+```
+
+### 4. Quantize the Model and Export
+
+Then we can apply the quantization. After quantizing, we need to freeze the
+quantized model first before exporting. Note that we need to export model with format of
+HuggingFace `safetensors`, you can refer to
+[HuggingFace format exporting](https://quark.docs.amd.com/latest/pytorch/export/quark_export_hf.html)
+for more exporting format details.
+
+```python
+import torch
+from quark.torch import ModelQuantizer, ModelExporter
+from quark.torch.export import ExporterConfig, JsonExporterConfig
+
+# Apply quantization.
+quantizer = ModelQuantizer(quant_config)
+quant_model = quantizer.quantize_model(model, calib_dataloader)
+
+# Freeze quantized model to export.
+freezed_model = quantizer.freeze(model)
+
+# Define export config.
+LLAMA_KV_CACHE_GROUP = ["*k_proj", "*v_proj"]
+export_config = ExporterConfig(json_export_config=JsonExporterConfig())
+export_config.json_export_config.kv_cache_group = LLAMA_KV_CACHE_GROUP
+
+EXPORT_DIR = MODEL_ID.split("/")[1] + "-w-fp8-a-fp8-kvcache-fp8-pertensor-autosmoothquant"
+exporter = ModelExporter(config=export_config, export_dir=EXPORT_DIR)
+with torch.no_grad():
+    exporter.export_safetensors_model(freezed_model,
+        quant_config=quant_config, tokenizer=tokenizer)
+```
+
+### 5. Evaluation in vLLM
+
+Now, you can load and run the Quark quantized model directly through the LLM entrypoint:
+
+```python
+from vllm import LLM, SamplingParams
+
+# Sample prompts.
+prompts = [
+    "Hello, my name is",
+    "The president of the United States is",
+    "The capital of France is",
+    "The future of AI is",
+]
+# Create a sampling params object.
+sampling_params = SamplingParams(temperature=0.8, top_p=0.95)
+
+# Create an LLM.
+llm = LLM(model="Llama-2-70b-chat-hf-w-fp8-a-fp8-kvcache-fp8-pertensor-autosmoothquant",
+          kv_cache_dtype='fp8',quantization='quark')
+# Generate texts from the prompts. The output is a list of RequestOutput objects
+# that contain the prompt, generated text, and other information.
+outputs = llm.generate(prompts, sampling_params)
+# Print the outputs.
+print("\nGenerated Outputs:\n" + "-" * 60)
+for output in outputs:
+    prompt = output.prompt
+    generated_text = output.outputs[0].text
+    print(f"Prompt:    {prompt!r}")
+    print(f"Output:    {generated_text!r}")
+    print("-" * 60)
+```
+
+Or, you can use `lm_eval` to evaluate accuracy:
+
+```console
+$ lm_eval --model vllm \
+  --model_args pretrained=Llama-2-70b-chat-hf-w-fp8-a-fp8-kvcache-fp8-pertensor-autosmoothquant,kv_cache_dtype='fp8',quantization='quark' \
+  --tasks gsm8k
+```
+
+## Quark Quantization Script
+In addition to the example of Python API above, Quark also offers a
+[quantization script](https://quark.docs.amd.com/latest/pytorch/example_quark_torch_llm_ptq.html)
+to quantize large language models more conveniently. It supports quantizing models with variety
+of different quantization schemes and optimization algorithms. It can export the quantized model
+and run evaluation tasks on the fly. With the script, the example above can be:
+
+```console
+python3 quantize_quark.py --model_dir meta-llama/Llama-2-70b-chat-hf \
+                          --output_dir /path/to/output \
+                          --quant_scheme w_fp8_a_fp8 \
+                          --kv_cache_dtype fp8 \

+                          --num_calib_data 512 \
+                          --model_export hf_format \
+                          --tasks gsm8k

+
+## Structured output
+
+The reasoning content is also available in the structured output. The structured output engine like `xgrammar` will use the reasoning content to generate structured output. It is only supported in v0 engine now.
+
+```bash
+VLLM_USE_V1=0 vllm serve deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B \
+    --enable-reasoning --reasoning-parser deepseek_r1
+```
+
+Please note that the `VLLM_USE_V1` environment variable must be set to `0` to use the v0 engine.
+
+```python
+from openai import OpenAI
+from pydantic import BaseModel
+
+# Modify OpenAI's API key and API base to use vLLM's API server.
+openai_api_key = "EMPTY"
+openai_api_base = "http://localhost:8000/v1"

+
+prompt = ("Generate a JSON with the name and age of one random person.")

+
+## Tool Calling
+
+The reasoning content is also available when both tool calling and the reasoning parser are enabled. Additionally, tool calling only parses functions from the `content` field, not from the `reasoning_content`.

+    ...
+```
+
+The structured output engine like `xgrammar` will use `end_token_id` to check if the reasoning content is present in the model output and skip the structured output if it is the case.
+
+Finally, you can enable reasoning for the model by using the `--enable-reasoning` and `--reasoning-parser` flags.
 
 ```bash
 vllm serve <model_tag> \

 # Tool Calling
 
-vLLM currently supports named function calling, as well as the `auto` and `none` options for the `tool_choice` field in the chat completion API. The `tool_choice` option `required` is **not yet supported** but [on the roadmap](gh-issue:13002).
+vLLM currently supports named function calling, as well as the `auto`, `required` (as of `vllm>=0.8.3`) and `none` options for the `tool_choice` field in the chat completion API.
 
 ## Quickstart

 To use a named function, you need to define the functions in the `tools` parameter of the chat completion request, and
 specify the `name` of one of the tools in the `tool_choice` parameter of the chat completion request.
 
+## Required Function Calling
+
+vLLM supports the `tool_choice='required'` option in the chat completion API. Similar to the named function calling, it also uses guided decoding, so this is enabled by default and will work with any supported model. The required guided decoding features (JSON schema with `anyOf`) are currently only supported in the V0 engine with the guided decoding backend `outlines`. However, support for alternative decoding backends are on the [roadmap](https://docs.vllm.ai/en/latest/getting_started/v1_user_guide.html#feature-model) for the V1 engine.
+
+When tool_choice='required' is set, the model is guaranteed to generate one or more tool calls based on the specified tool list in the `tools` parameter. The number of tool calls depends on the user's query. The output format strictly follows the schema defined in the `tools` parameter.

+For Qwen2.5, the chat template in tokenizer_config.json has already included support for the Hermes-style tool use. Therefore, you can use the `hermes` parser to enable tool calls for Qwen models.

 ### Models with Pythonic Tool Calls (`pythonic`)
 
 A growing number of models output a python list to represent tool calls instead of using JSON. This has the advantage of inherently supporting parallel tool calls and removing ambiguity around the JSON schema required for tool calls. The `pythonic` tool parser can support such models.

-## Supported features
-
-OpenVINO vLLM backend supports the following advanced vLLM features:
-
-- Prefix caching (`--enable-prefix-caching`)
-- Chunked prefill (`--enable-chunked-prefill`)
-
-## Performance tips
-
-### vLLM OpenVINO backend environment variables
-
-- `VLLM_OPENVINO_DEVICE` to specify which device utilize for the inference. If there are multiple GPUs in the system, additional indexes can be used to choose the proper one (e.g, `VLLM_OPENVINO_DEVICE=GPU.1`). If the value is not specified, CPU device is used by default.
-- `VLLM_OPENVINO_ENABLE_QUANTIZED_WEIGHTS=ON` to enable U8 weights compression during model loading stage. By default, compression is turned off. You can also export model with different compression techniques using `optimum-cli` and pass exported folder as `<model_id>`
-
-### CPU performance tips
-
-CPU uses the following environment variables to control behavior:
-
-- `VLLM_OPENVINO_KVCACHE_SPACE` to specify the KV Cache size (e.g, `VLLM_OPENVINO_KVCACHE_SPACE=40` means 40 GB space for KV cache), larger setting will allow vLLM running more requests in parallel. This parameter should be set based on the hardware configuration and memory management pattern of users.
-- `VLLM_OPENVINO_CPU_KV_CACHE_PRECISION=u8` to control KV cache precision. By default, FP16 / BF16 is used depending on platform.
-

-### GPU performance tips
-
-GPU device implements the logic for automatic detection of available GPU memory and, by default, tries to reserve as much memory as possible for the KV cache (taking into account `gpu_memory_utilization` option). However, this behavior can be overridden by explicitly specifying the desired amount of memory for the KV cache using `VLLM_OPENVINO_KVCACHE_SPACE` environment variable (e.g, `VLLM_OPENVINO_KVCACHE_SPACE=8` means 8 GB space for KV cache).
-
-Currently, the best performance using GPU can be achieved with the default vLLM execution parameters for models with quantized weights (8 and 4-bit integer data types are supported) and `preemption-mode=swap`.
-
-OpenVINO best known configuration for GPU is:

 - Decouple the HTTP serving components from the inference components. In a GPU backend configuration, the HTTP serving and tokenization tasks operate on the CPU, while inference runs on the GPU, which typically does not pose a problem. However, in a CPU-based setup, the HTTP serving and tokenization can cause significant context switching and reduced cache efficiency. Therefore, it is strongly recommended to segregate these two components for improved performance.
 
-- On CPU based setup with NUMA enabled, the memory access performance may be largely impacted by the [topology](https://github.com/intel/intel-extension-for-pytorch/blob/main/docs/tutorials/performance_tuning/tuning_guide.inc.md#non-uniform-memory-access-numa). For NUMA architecture, two optimizations are to recommended: Tensor Parallel or Data Parallel.

For NUMA architecture, Tensor Parallel is a option for better performance.
 
-  - Using Tensor Parallel for a latency constraints deployment: following GPU backend design, a Megatron-LM's parallel algorithm will be used to shard the model, based on the number of NUMA nodes (e.g. TP = 2 for a two NUMA node system). With [TP feature on CPU](gh-pr:6125) merged, Tensor Parallel is supported for serving and offline inferencing. In general each NUMA node is treated as one GPU card.

     ```
 
-  - Using Data Parallel for maximum throughput: to launch an LLM serving endpoint on each NUMA node along with one additional load balancer to dispatch the requests to those endpoints. Common solutions like [Nginx](#nginxloadbalancer) or HAProxy are recommended. Anyscale Ray project provides the feature on LLM [serving](https://docs.ray.io/en/latest/serve/index.html). Here is the example to setup a scalable LLM serving with [Ray Serve](https://github.com/intel/llm-on-ray/blob/main/docs/setup.inc.md).
+  - For each thread id list in `VLLM_CPU_OMP_THREADS_BIND`, users should guarantee threads in the list belong to a same NUMA node.
+
+  - Meanwhile, users should also take care of memory capacity of each NUMA node. The memory usage of each TP rank is the sum of `weight shard size` and `VLLM_CPU_KVCACHE_SPACE`, if it exceeds the capacity of a single NUMA node, TP worker will be killed due to out-of-memory.

 If the model is too large to fit in a single GPU, you will get an out-of-memory (OOM) error. Consider [using tensor parallelism](#distributed-serving) to split the model across multiple GPUs. In that case, every process will read the whole model and split it into chunks, which makes the disk reading time even longer (proportional to the size of tensor parallelism). You can convert the model checkpoint to a sharded checkpoint using <gh-file:examples/offline_inference/save_sharded_state.py>.

+## Generation quality changed
+
+In v0.8.0, the source of default sampling parameters was changed in <gh-pr:12622>. Prior to v0.8.0, the default sampling parameters came from vLLM's set of neutral defaults. From v0.8.0 onwards, the default sampling parameters come from the `generation_config.json` provided by the model creator.

+In most cases, this should lead to higher quality responses, because the model creator is likely to know which sampling parameters are best for their model. However, in some cases the defaults provided by the model creator can lead to degraded performance.

+## Why vLLM V1?
+
+vLLM V0 successfully supported a wide range of models and hardware, but as new features were developed independently, the system grew increasingly complex. This complexity made it harder to integrate new capabilities and introduced technical debt, revealing the need for a more streamlined and unified design.
+
+Building on V0’s success, vLLM V1 retains the stable and proven components from V0
+(such as the models, GPU kernels, and utilities). At the same time, it significantly
+re-architects the core systems, covering the scheduler, KV cache manager, worker,
+sampler, and API server, to provide a cohesive, maintainable framework that better
+accommodates continued growth and innovation.
+
+Specifically, V1 aims to:

+- Provide a **simple, modular, and easy-to-hack codebase**.
+- Ensure **high performance** with near-zero CPU overhead.
+- **Combine key optimizations** into a unified architecture.
+- Require **zero configs** by enabling features/optimizations by default.
+
+We see significant performance improvements from upgrading to V1 core engine, in
+particular for long context scenarios. Please see performance benchmark (To be
+added).

+For more details, check out the vLLM V1 blog post [vLLM V1: A Major
+Upgrade to vLLM’s Core Architecture](https://blog.vllm.ai/2025/01/27/v1-alpha-release.html) (published Jan 27, 2025).
+
+This living user guide outlines a few known **important changes and limitations** introduced by vLLM V1. The team has been working actively to bring V1 as the default engine, therefore this guide will be updated constantly as more features get supported on vLLM V1.

+- **🟢 Functional**: Fully operational, with ongoing optimizations.  
+- **🚧 WIP**: Under active development.  
+- **🟡 Planned**: Scheduled for future implementation (some may have open PRs/RFCs).  
+- **🔴 Deprecated**: Not planned for v1 unless there is strong demand.
+
+**Note**: vLLM V1’s unified scheduler treats both prompt and output tokens the same
+way by using a simple dictionary (e.g., {request_id: num_tokens}) to dynamically
+allocate a fixed token budget per request, enabling features like chunked prefills,
+prefix caching, and speculative decoding without a strict separation between prefill
+and decode phases.
+
+### Semantic Changes and Deprecated Features
+
+#### Logprobs
+
+vLLM V1 supports logprobs and prompt logprobs. However, there are some important semantic
+differences compared to V0:
+
+**Logprobs Calculation**
+
+Logprobs in V1 are now returned immediately once computed from the model’s raw output (i.e.
+before applying any logits post-processing such as temperature scaling or penalty
+adjustments). As a result, the returned logprobs do not reflect the final adjusted
+probabilities used during sampling.
+
+Support for logprobs with post-sampling adjustments is in progress and will be added in future updates.
+
+**Prompt Logprobs with Prefix Caching**
+
+Currently prompt logprobs are only supported when prefix caching is turned off via `--no-enable-prefix-caching`. In a future release, prompt logprobs will be compatible with prefix caching, but a recomputation will be triggered to recover the full prompt logprobs even upon a prefix cache hit. See details in [RFC #13414](https://github.com/vllm-project/vllm/issues/13414).
+
+#### Deprecated Features
+
+As part of the major architectural rework in vLLM V1, several legacy features have been deprecated.
+
+**Sampling features**
+
+- **best_of**: This feature has been deprecated due to limited usage. See details at [RFC #13361](https://github.com/vllm-project/vllm/issues/13361).
+- **Per-Request Logits Processors**: In V0, users could pass custom
+  processing functions to adjust logits on a per-request basis. In vLLM V1, this
+  feature has been deprecated. Instead, the design is moving toward supporting **global logits
+  processors**, a feature the team is actively working on for future releases. See details at [RFC #13360](https://github.com/vllm-project/vllm/pull/13360).
+
+**KV Cache features**
+
+- **GPU <> CPU KV Cache Swapping**: with the new simplified core architecture, vLLM V1 no longer requires KV cache swapping
+to handle request preemptions.
+
+**Structured Output features**
+
+- **Request-level Structured Output Backend**: Deprecated, alternative backends
+  (outlines, guidance) with fallbacks is WIP.
+### Feature & Model Support in Progress
+
+Although we have re-implemented and partially optimized many features and models from V0 in vLLM V1, optimization work is still ongoing for some, and others remain unsupported.
+
+#### Features to Be Optimized
+
+These features are already supported in vLLM V1, but their optimization is still
+in progress.
+
+- **LoRA**: LoRA is functionally working on vLLM V1 but its performance is
+  inferior to that of V0. The team is actively working on improving its
+  performance
+(e.g., see [PR #13096](https://github.com/vllm-project/vllm/pull/13096)).
+
+- **Spec Decode**: Currently, only ngram-based spec decode is supported in V1. There
+  will be follow-up work to support other types of spec decode (e.g., see [PR #13933](https://github.com/vllm-project/vllm/pull/13933)). We will prioritize the support for Eagle, MTP compared to draft model based spec decode.
+
+- **Multimodal Models**: V1 is almost fully compatible with V0 except that interleaved modality input is not supported yet.
+  See [here](https://github.com/orgs/vllm-project/projects/8) for the status of upcoming features and optimizations.
+
+#### Features to Be Supported
+
+- **Structured Output Alternative Backends**: Structured output alternative backends (outlines, guidance) support is planned. V1 currently
+  supports only the `xgrammar:no_fallback` mode, meaning that it will error out if the output schema is unsupported by xgrammar.
+  Details about the structured outputs can be found
+  [here](https://docs.vllm.ai/en/latest/features/structured_outputs.html).
+
+#### Models to Be Supported
+
+vLLM V1 currently excludes model architectures with the `SupportsV0Only` protocol,
+and the majority fall into the following categories. V1 support for these models will be added eventually.
+
+**Embedding Models**  
+Instead of having a separate model runner, hidden states processor [RFC #12249](https://github.com/vllm-project/vllm/issues/12249), which is based on global logits processor [RFC #13360](https://github.com/vllm-project/vllm/pull/13360), has been proposed to enable simultaneous generation and embedding using the same engine instance in V1. It is still in the planning stage.
+
+**Mamba Models**  
+Models using selective state-space mechanisms (instead of standard transformer attention)
+are not yet supported (e.g., `MambaForCausalLM`, `JambaForCausalLM`).
+
+**Encoder-Decoder Models**  
+vLLM V1 is currently optimized for decoder-only transformers. Models requiring
+  cross-attention between separate encoder and decoder are not yet supported (e.g., `BartForConditionalGeneration`, `MllamaForConditionalGeneration`).
+
+For a complete list of supported models, see the [list of supported models](https://docs.vllm.ai/en/latest/models/supported_models.html).
+
+## Frequently Asked Questions
+
+**I'm using vLLM V1 and I'm getting CUDA OOM errors. What should I do?**
+The default `max_num_seqs` has been raised from `256` in V0 to `1024` in V1. If you encounter CUDA OOM only when using V1 engine, try setting a lower value of `max_num_seqs` or `gpu_memory_utilization`.
+
+On the other hand, if you get an error about insufficient memory for the cache blocks, you should increase `gpu_memory_utilization` as this indicates that your GPU has sufficient memory but you're not allocating enough to vLLM for KV cache blocks.

-vLLM supports generative and pooling models across various tasks.
+vLLM supports [generative](generative-models) and [pooling](pooling-models) models across various tasks.
 If a model supports more than one task, you can set the task via the `--task` argument.
 
 For each task, we list the model architectures that have been implemented in vLLM.
 Alongside each architecture, we include some popular models that use it.
 
-## Loading a Model
-
-### HuggingFace Hub
-
-By default, vLLM loads models from [HuggingFace (HF) Hub](https://huggingface.co/models).
+## Model Implementation
 
-To determine whether a given model is supported, you can check the `config.json` file inside the HF repository.
-If the `"architectures"` field contains a model architecture listed below, then it should be supported in theory.
-
-:::{tip}
-The easiest way to check if your model is really supported at runtime is to run the program below:
-
-```python
-from vllm import LLM
+### vLLM
 
-# For generative models (task=generate) only
-llm = LLM(model=..., task="generate")  # Name or path of your model
-output = llm.generate("Hello, my name is")
-print(output)
-
-# For pooling models (task={embed,classify,reward,score}) only
-llm = LLM(model=..., task="embed")  # Name or path of your model
-output = llm.encode("Hello, my name is")
-print(output)
-```
+If vLLM natively supports a model, its implementation can be found in <gh-file:vllm/model_executor/models>.
 
-If vLLM successfully returns text (for generative models) or hidden states (for pooling models), it indicates that your model is supported.
-:::
+These models are what we list in <project:#supported-text-models> and <project:#supported-mm-models>.
 
-Otherwise, please refer to [Adding a New Model](#new-model) for instructions on how to implement your model in vLLM.
-Alternatively, you can [open an issue on GitHub](https://github.com/vllm-project/vllm/issues/new/choose) to request vLLM support.

-#### Supported features
-
-##### Quantization
-
-Transformers fallback has supported most of available quantization in vLLM (except GGUF). See [Quantization page](#quantization-index) for more information about supported quantization in vllm.
-
-##### LoRA
+:::{tip}
+You can force the use of `TransformersForCausalLM` by setting `model_impl="transformers"` for <project:#offline-inference> or `--model-impl transformers` for the <project:#openai-compatible-server>.
+:::
 
-LoRA hasn't supported on transformers fallback yet! Make sure to open an issue and we'll work on this together with the `transformers` team!
+:::{note}
+vLLM may not fully optimise the Transformers implementation so you may see degraded performance if comparing a native model to a Transformers model in vLLM.
+:::
 
-Usually `transformers` model load weights via the `load_adapters` API, that depends on PEFT. We need to work a bit to either use this api (for now this would result in some weights not being marked as loaded) or replace modules accordingly.
+#### Supported features
 
-Hints as to how this would look like:
+The Transformers modeling backend explicitly supports the following features:
 
-```python
-class TransformersModel(nn.Module, SupportsLoRA):
-  def __init__(*):
-    ...
-    self.model.load_adapter(vllm_config.load_config.model_loader_extra_config["qlora_adapter_name_or_path"])
-```
+- <project:#quantization-index> (except GGUF)
+- <project:#lora-adapter>
+- <project:#distributed-serving>
 
-Blocker is that you need to specify supported lora layers, when we would ideally want to load whatever is inside the checkpoint!
+#### Remote Code
 
-##### Remote code
+If your model is neither supported natively by vLLM or Transformers, you can still run it in vLLM!
 
-This fallback also means that any model on the hub that can be used in `transformers` with `trust_remote_code=True` that correctly implements attention can be used in production!
+Simply set `trust_remote_code=True` and vLLM will run any model on the Model Hub that is compatible with Transformers.
+Provided that the model writer implements their model in a compatible way, this means that you can run new models before they are officially supported in Transformers or vLLM!
 
-```python 
+```python
 from vllm import LLM
 llm = LLM(model=..., task="generate", trust_remote_code=True)  # Name or path of your model
 llm.apply_model(lambda model: print(model.__class__))
 ```
 
-A model just needs the following two things:
+To make your model compatible with the Transformers backend, it needs:

+- `base_model_tp_plan` is a `dict` that maps fully qualified layer name patterns to tensor parallel styles (currently only `"colwise"` and `"rowwise"` are supported).
+- `base_model_pp_plan` is a `dict` that maps direct child layer names to `tuple`s of `list`s of `str`s:
+  * You only need to do this for layers which are not present on all pipeline stages
+  * vLLM assumes that there will be only one `nn.ModuleList`, which is distributed across the pipeline stages

+
+## Loading a Model
+
+### Hugging Face Hub
+
+By default, vLLM loads models from [Hugging Face (HF) Hub](https://huggingface.co/models).
+
+To determine whether a given model is natively supported, you can check the `config.json` file inside the HF repository.
+If the `"architectures"` field contains a model architecture listed below, then it should be natively supported.
+
+Models do not _need_ to be natively supported to be used in vLLM.
+The [Transformers backend](#transformers-backend) enables you to run models directly using their Transformers implementation (or even remote code on the Hugging Face Model Hub!).
+
+:::{tip}
+The easiest way to check if your model is really supported at runtime is to run the program below:
+
+```python
+from vllm import LLM
+
+# For generative models (task=generate) only
+llm = LLM(model=..., task="generate")  # Name or path of your model
+output = llm.generate("Hello, my name is")
+print(output)
+
+# For pooling models (task={embed,classify,reward,score}) only
+llm = LLM(model=..., task="embed")  # Name or path of your model
+output = llm.encode("Hello, my name is")
+print(output)
+```
+
+If vLLM successfully returns text (for generative models) or hidden states (for pooling models), it indicates that your model is supported.
+:::
+
+Otherwise, please refer to [Adding a New Model](#new-model) for instructions on how to implement your model in vLLM.
+Alternatively, you can [open an issue on GitHub](https://github.com/vllm-project/vllm/issues/new/choose) to request vLLM support.

+vLLM supports distributed tensor-parallel and pipeline-parallel inference and serving. Currently, we support [Megatron-LM's tensor parallel algorithm](https://arxiv.org/pdf/1909.08053.pdf). We manage the distributed runtime with either [Ray](https://github.com/ray-project/ray) or python native multiprocessing. Multiprocessing can be used when deploying on a single node, multi-node inference currently requires Ray.
 
 Multiprocessing will be used by default when not running in a Ray placement group and if there are sufficient GPUs available on the same node for the configured `tensor_parallel_size`, otherwise Ray will be used. This default can be overridden via the `LLM` class `distributed_executor_backend` argument or `--distributed-executor-backend` API server argument. Set it to `mp` for multiprocessing or `ray` for Ray. It's not required for Ray to be installed for the multiprocessing case.

+Our Score API can apply a cross-encoder model or an embedding model to predict scores for sentence pairs. When using an embedding model the score corresponds to the cosine similarity between each embedding pair.
 Usually, the score for a sentence pair refers to the similarity between two sentences, on a scale of 0 to 1.

+# Reinforcement Learning from Human Feedback
+
+Reinforcement Learning from Human Feedback (RLHF) is a technique that fine-tunes language models using human-generated preference data to align model outputs with desired behaviors.
+
+vLLM can be used to generate the completions for RLHF. The best way to do this is with libraries like [TRL](https://github.com/huggingface/trl), [OpenRLHF](https://github.com/OpenRLHF/OpenRLHF) and [verl](https://github.com/volcengine/verl).
+
+See the following basic examples to get started if you don't want to use an existing library:

+- [Training and inference processes are located on separate GPUs (inspired by OpenRLHF)](https://docs.vllm.ai/en/latest/getting_started/examples/rlhf.html)
+- [Training and inference processes are colocated on the same GPUs using Ray](https://docs.vllm.ai/en/latest/getting_started/examples/rlhf_colocate.html)

+# Transformers Reinforcement Learning
+
+Transformers Reinforcement Learning (TRL) is a full stack library that provides a set of tools to train transformer language models with methods like Supervised Fine-Tuning (SFT), Group Relative Policy Optimization (GRPO), Direct Preference Optimization (DPO), Reward Modeling, and more. The library is integrated with 🤗 transformers.
+
+Online methods such as GRPO or Online DPO require the model to generate completions. vLLM can be used to generate these completions!
+
+See the guide [vLLM for fast generation in online methods](https://huggingface.co/docs/trl/main/en/speeding_up_training#vllm-for-fast-generation-in-online-methods) in the TRL documentation for more information.

+This file implements common components for MLA implementations.
+
+First we define:
+
+Sq      as Q sequence length
+Skv     as KV sequence length
+
+MLA has two possible ways of computing, a data-movement friendly approach and a
+compute friendly approach, we generally want to use the compute friendly
+approach for "prefill" (i.e. the ratio Sq / Skv is "small", is near 1)
+and the data-movement friendly approach for "decode" (i.e. the ratio
+Sq / Skv is "large").
+
+NOTE what we deem small and large is currently determined by if its labelled
+prefill or decode by the scheduler, but this is something we should probably
+tune.
+
+Main reference: DeepseekV2 paper, and FlashInfer Implementation
+(https://arxiv.org/abs/2405.04434 and https://github.com/flashinfer-ai/flashinfer/pull/551).
+
+Deepseek's MLA attention works the following way:
+* Use a single latent vector to represent the per-token entry of the KV cache.
+* For decode (i.e. the memory friendly approach) the attention "simulates" a
+multi-head attention, while the compute is similar to multi-query attention.
+
+Below is example of both paths assuming batchsize = 1
+
+## More Extent Definitions:

+Lkv         latent dimension for K/V            512 in DSV3
+P           nope dimension, no rope.            128 in DSV3

+## Compute Friendly Approach (i.e. "_forward_prefill"):
+
+q_c      = h_t @ W_DQ
+q_nope   = (q_c @ W_UQ).view(Sq, N, P)
+q_pe     = RoPE(q_c @ W_QR).view(Sq, N, R)
+new_kv_c = h_t @ W_DKV
+new_k_pe = RoPE(h_t @ W_KR)
+kv_c     = torch.cat([new_kv_c, cache_kv_c], dim=0)
+k_pe     = torch.cat([new_k_pe, cache_k_pe], dim=0)
+k_nope   = (kv_c @ W_UK.view(Lkv, N * P)).view(Skv, N, P)
+v        = (kv_c @ W_UV.view(Lkv, N * V)).view(Skv, N, V)
+
+// MHA with QK headdim = P + R
+//           V headdim = V
+//      spda_o shape [Sq, N, V]
+spda_o = scaled_dot_product_attention(
+    torch.cat([q_nope, q_pe], dim=-1),
+    torch.cat([k_nope, k_pe.unsqueeze(1).expand(-1, N, -1)], dim=-1),
+    v
+) 
+return spda_o @ W_O
+
+NOTE: in the actual code, 
+    `kv_b_proj` is [W_UK; W_UV] concatnated per head
+    `q_b_proj` is [W_UQ; W_QR] concatnated per head
+    `out_proj` is W_O
+

+q_c      = h_t @ W_DQ
+q_nope   = (q_c @ W_UQ).view(-1, N, P)

+kv_c     = torch.cat([new_kv_c, cache_kv_c], dim=0)
+k_pe     = torch.cat([new_k_pe, cache_k_pe], dim=0)
+
+// MQA with QK headdim = Lkv + R
+//           V headdim = Lkv
+//      spda_o shape [Sq, N, Lkv]
+// NOTE: this is less compute-friendly since Lkv > P
+//       but is more data-movement friendly since its MQA vs MHA
+spda_o = scaled_dot_product_attention(
+    torch.cat([ql_nope, q_pe], dim=-1),
+    torch.cat([kv_c, k_pe], dim=-1),
+    kv_c
+)
+
+o = einsum("snl,lnv->snv", spda_o.reshape(-1, N, Lkv), W_UV)
+return o.view(-1, N * V) @ self.num_heads @ W_O
+
+
+## Chunked Prefill
+
+For chunked prefill we want to use the compute friendly algorithm. We are 
+assuming sufficiently large Sq / Skv ratio, in the future may want to switch to 
+the data-movement friendly approach if the chunk (i.e. `Sq`) is small.
+
+However, the compute-friendly approach can potentially run out of memory if Skv
+is large due to: `k_nope = (kv_c @ W_UK).view(Skv, N, P)`
+
+To mitigate this, we chunk the computation of attention with respect to the 
+current context (i.e. `cache_kv_c` and `cache_k_pe`) so that we can used a 
+fixed workspace size.
+
+The chunked prefill approach is as follows:
+
+MCC        Max chunk of context to process per iter, computed dynamically, 
+           used to bound the memory usage
+
+q_c        = h_t @ W_DQ
+q_nope     = (q_c @ W_UQ).view(Sq, N, P)
+q_pe       = RoPE(q_c @ W_QR).view(Sq, N, R)
+new_kv_c   = h_t @ W_DKV
+new_k_pe   = RoPE(h_t @ W_KR)
+new_k_nope = (new_kv_c @ W_UK.view(Lkv, N * P)).view(Sq, N, P)
+new_v      = (new_kv_c @ W_UV.view(Lkv, N * V)).view(Sq, N, V)
+
+// MHA between queries and new KV
+//     with QK headdim = P + R
+//           V headdim = V
+//    curr_o   shape [Sq, N, V]
+//    curr_lse shape [N, Sq], this is just order FA returns
+curr_o, curr_lse = scaled_dot_product_attention(
+    torch.cat([q_nope, q_pe], dim=-1),
+    torch.cat([new_k_nope, new_k_pe.unsqueeze(1).expand(-1, N, -1)], dim=-1),

+    Sc           = chunk_end - chunk_start
+    cache_kv_c_chunk   = cache_kv_c[chunk_start:chunk_end]
+    cache_k_pe_chunk   = cache_k_pe[chunk_start:chunk_end]

-    Common class for implementing repeated parts
-
-    Main reference: DeepseekV2 paper, and FlashInfer Implementation
-    (https://arxiv.org/abs/2405.04434 and https://github.com/flashinfer-ai/flashinfer/pull/551).
-
-    Deepseek's MLA attention works the following way:
-    * Use a single latent vector to represent the entire KV cache.
-    * The attention "simulates" a multi-head attention, while the compute is
-      similar to multi-query attention.
-    * The dataflow is as follows,
-
-        * B: batch/sequence length
-        * H: hidden size
-        * N: number of attention heads
-        * Lq: latent dimension for Q
-        * Lkv: latent dimension for K/V
-        * P: nope dimension, P+R is the actual head_dim in common attention.
-        * R: rope dimension, this slide of the head_dim goes through rope.
-        * V: V head dim.
-        * kv_c: latent/compressed KV
-        * q_c: latent/compressed Q
-
-        #
-        # Outside the MLA attention backend
-        #
-
-        1. The hidden states (B, H) are projected down into cq (B, Lq) and
-           kv_c_k_pe (B, Lkv+R).
-        2. The kv_c_k_pe is split into kv_c (B, Lkv) and k_pe (B, R). cq
-           and kv_c are normalized.
-
-        #
-        # Inside the MLA attention backend
-        #
-
-        * if prefill:
-
-        3. The q_c is then projected up into the multi-head version.
-           * q_c goes from (B, Lq) to (B, N, (P+R)), which is split into q_nope
-             (B, N, P) and q_pe (B, N, R).
-        4. q_pe, k_pe are then passed through rotary embeddings.
-        5. kv_c and k_pe are concatenated and inserted into the cache
-        6. The kv_c is then projected up into the multi-head version.
-           * kv_c goes from (B, Lkv) to (B, N, (P+V)) which has the nope
-             dimensions for K and V, which is split into k_nope (B, N, P)
-             and v (B, N, V).
-        7. q (B, N, (P+R)) and k (B, N, (P+R)) matrices are assembled from
-           q_nope, q_pe, k_nope, k_pe.
-        8. Attention is computued with q, k, v.
-        9. The attention computation returns (B, N, V), which is projected back
-           to (B, H) using out projection.
-
-        * if decode:
-
-        3. Here's the change, we do not perform up the full up projection for
-           q_c, and there is no up projection at all for kv_c. This is
-           achieved by the technique of "weight absorption". The paper says
-           "Fortunately, due to the associative law of matrix multiplication,
-           we can absorb WUK into WUQ, and WUV into WO"
-           * The q up projection turns (B, Lq) into (B, N, (P+R)), we split it
-             into W_UQ (Lq, N, P) and W_QR (Lq, N, R).
-           * The kv_c up projection turns (B, Lkv) into (B, N, (P+V)), we split
-             it into W_UK (Lkv, N, P) and W_UV (Lkv, N, V).
-           * The out projection shape W_O (N*V, H) turns (B, N, V) into (B, H).
-           * We can precompute the product of W_UQ and W_UK into
-             W_UQ_UK (Lq, N, Lkv), which is possible due to QK^T operation in
-             attention.
-           * We can precompute the product of W_UV and W_O into
-             W_UV_O (N, Lkv, H), which is possible due to V@O as the
-             "epilogue" of attention
-        4. We still need to compute q_pe (B, N, R) by applying W_QR to q_latent.
-        5. q_pe, k_pe are then passed through rotary embeddings.
-        6. kv_c and k_pe are concatenated and inserted into the cache
-        7. By applying W_UQ_UK to q_latent, we have the new q_nope of shape
-           (B, N, Lkv).
-        8. q (B, N, (Lkv+R)), k (B, (Lkv+R)) are assembled from q_nope, q_pe,
-           kv_a, k_pe. v (B, Lkv) is exactly the same vector as kv_a.
-        9. The attention is computed with q, k, v. Note that we just performed
-           a MQA attention with (LKv+R) as our head dim.
-        10. The KV cache is updated using the new entries k (B, N, (Lkv+R)),
-           which included the v and rope values.
-        11. The attention computation returns (B, N, Lkv), which is projected
-           back to (B, H) using W_UV_O.
-
-    From @tsu-bin's calculation, we only want to use the absorption technique
-    for decode. The prefill algorithm should still use the up-projected MHA
-    for less flops and memory usage.

+                        A threshold value that sets a lower bound on the
+                        posterior probability of a token in the target model
+                        for it to be accepted. This threshold is used only
+                        when we use the TypicalAcceptanceSampler for token
+                        acceptance.
+                    - posterior_alpha (Optional[float]):
+                        Scaling factor for entropy-based threshold, applied
+                        when using TypicalAcceptanceSampler.
+        - draft_tensor_parallel_size (Optional[int]): The degree of the tensor
+            parallelism for the draft model. Can only be 1 or the same as the
+            target model's tensor parallel size.
+        - disable_logprobs (bool): If set to True, token log probabilities are
+            not returned during speculative decoding. If set to False, token
+            log probabilities are returned according to the log probability
+            settings in SamplingParams. If not specified, it defaults to True.
+
+    - Draft Model Configuration:
+        - quantization (Optional[str]): Quantization method that was used to
+            quantize the draft model weights. If None, we assume the
+            model weights are not quantized. Note that it only takes effect
+            when using the draft model-based speculative method.
+        - max_model_len (Optional[int]): The maximum model length of the
+            draft model. Used when testing the ability to skip
+            speculation for some sequences.
+        - revision: The specific model version to use for the draft model. It
+            can be a branch name, a tag name, or a commit id. If unspecified,
+            will use the default version.
+        - code_revision: The specific revision to use for the draft model code
+            on Hugging Face Hub. It can be a branch name, a tag name, or a
+            commit id. If unspecified, will use the default version.
 
-    The configuration is currently specialized to draft-model speculative
-    decoding with top-1 proposals.
+    - Advanced Control:
+        - disable_mqa_scorer (bool): Disable the MQA scorer and fall back to
+            batch expansion for scoring proposals. If not specified, it
+            defaults to False.
+        - disable_by_batch_size (Optional[int]): Disable speculative decoding
+            for new incoming requests when the number of enqueued requests is
+            larger than this value, if provided.
+
+    Although the parameters above are structured hierarchically, there is no
+    need to nest them during configuration.
+
+    Non-configurable internal parameters include:
+    - Model Configuration:
+        - target_model_config (ModelConfig): The configuration of the target
+            model.
+        - draft_model_config (ModelConfig): The configuration of the draft
+            model initialized internal.
+    - Parallelism Configuration:
+        - target_parallel_config (ParallelConfig): The parallel configuration
+            for the target model.
+        - draft_parallel_config (ParallelConfig): The parallel configuration
+            for the draft model initialized internal.
+    - Execution Control:
+        - enable_chunked_prefill (bool): Whether vLLM is configured to use
+            chunked prefill or not. Used for raising an error since it's not
+            yet compatible with speculative decode.
+        - disable_log_stats (bool): Whether to disable the periodic printing of
+            stage times in speculative decoding.

+
+    # TODO: ask for help from PyTorch team if we need the `broadcast` operation.
+
+    This function is useful when we are not sure about the total number of
+    processes in the process group. For example, we may have process
+    1, 2, ..., 8 who want to communicate, and process 9 might be the same
+    process as process 1, or it might be a different process; process 10
+    might be the same process as process 5, or it might be a different process.
+    In this case, how can we reliably form a communication channel within

+
+    One possible solution is to figure out if process 9 and 10 are the same

+    based on the information, adjusting the ranks and world_size etc. However,
+    figuring out the information is not always easy, and it will interfere
+    with the main communication channel.
+
+    Our solution is to always form a communication channel with process 1, 2,
+    ..., 8, and then use this function to form another communication channel
+    with process 9 and 10. This way, regardless of whether process 9 and 10
+    are the same as process 1 and 5, the main communication channel is
+    always formed with process 1, 2, ..., 8, and the additional communication

-    Aligns the token distribution across experts to be compatible with block
-    size for matrix multiplication.
-
-    Parameters:
-    - topk_ids: A tensor of shape [total_tokens, top_k] representing the
-        top-k expert indices for each token.
-    - block_size: The block size used in block matrix multiplication.
-    - num_experts: The total number of experts.
-
-    Returns:
-    - sorted_token_ids: A tensor containing the sorted token indices according
-        to their allocated expert.
-    - expert_ids: A tensor indicating the assigned expert index for each block.
-    - num_tokens_post_padded: The total number of tokens after padding,
-        ensuring divisibility by block_size.
-
-    This function pads the number of tokens that each expert needs to process
-    so that it is divisible by block_size.
-    Padding ensures that during block matrix multiplication, the dimensions
-    align correctly.
-
-    Example:
-    Given topk_ids = [[2, 3, 4], [1, 2, 4], [1, 3, 4], [1, 2, 3]],
-    block_size = 4, and num_experts = 4:
-    - We initially have 12 tokens (after repeating 'top_k' times) and 4 experts,
-        with each expert needing to process 3 tokens.
-    - As block_size is 4, we pad 1 token for each expert.
-    - First, flatten topk_ids to [2, 3, 4, 1, 2, 4, 1, 3, 4, 1, 2, 3].
-    - Then append padding tokens [12, 12, 12, 12] for each block.
-    - After sorting by expert index, we obtain token_ids
-        [3, 6, 9, 12, 0, 4, 10, 12, 1, 7, 11, 12, 2, 5, 8, 12].
-        Tokens 12 are non-existent (padding) and are ignored in
-        the subsequent matrix multiplication.
-    - The padding ensures that the total number of tokens is now divisible
-        by block_size for proper block matrix operations.

+    Aligns the token distribution across experts to be compatible with block
+    size for matrix multiplication.
+
+    Parameters:
+    - topk_ids: A tensor of shape [total_tokens, top_k] representing the
+        top-k expert indices for each token.
+    - block_size: The block size used in block matrix multiplication.
+    - num_experts: The total number of experts.
+    - expert_map: A tensor of shape [num_experts] that maps the expert index
+        from the global space to the local index space of the current
+        expert parallel shard. If the expert is not in the current expert
+        parallel shard, the mapping is set to -1.
+    - pad_sorted_ids: A flag indicating whether the sorted_token_ids length
+      should be padded to a multiple of block_size,
+
+    Returns:
+    - sorted_token_ids: A tensor containing the sorted token indices according
+        to their allocated expert.
+    - expert_ids: A tensor indicating the assigned expert index for each block.
+    - num_tokens_post_padded: The total number of tokens after padding,
+        ensuring divisibility by block_size.
+
+    This function pads the number of tokens that each expert needs to process
+    so that it is divisible by block_size.
+    Padding ensures that during block matrix multiplication, the dimensions
+    align correctly.
+
+    Example:
+    Given topk_ids = [[2, 3, 4], [1, 2, 4], [1, 3, 4], [1, 2, 3]],
+    block_size = 4, and num_experts = 4:
+    - We initially have 12 tokens (after repeating 'top_k' times) and 4 experts,
+        with each expert needing to process 3 tokens.
+    - As block_size is 4, we pad 1 token for each expert.
+    - First, flatten topk_ids to [2, 3, 4, 1, 2, 4, 1, 3, 4, 1, 2, 3].
+    - Then append padding tokens [12, 12, 12, 12] for each block.
+    - After sorting by expert index, we obtain token_ids
+        [3, 6, 9, 12, 0, 4, 10, 12, 1, 7, 11, 12, 2, 5, 8, 12].
+        Tokens 12 are non-existent (padding) and are ignored in
+        the subsequent matrix multiplication.
+    - The padding ensures that the total number of tokens is now divisible
+        by block_size for proper block matrix operations.

+
+        One key thing to understand is the `input_ids` already accounts for the
+        positions of the to-be-inserted image embeddings.
+
+        Concretely, consider a text prompt:
+        `"USER: <image>\\nWhat's the content of the image?\\nASSISTANT:"`.
+
+        Tokenizer outputs:
+        `[1, 3148, 1001, 29901, 29871, 32000, 29871, 13, 5618, 29915, 29879,
+        278, 2793, 310, 278, 1967, 29973, 13, 22933, 9047, 13566, 29901]`.
+
+        To reserve space in KV cache, we have to insert placeholder tokens
+        before they are inputted to the model, so the input processor prepends
+        additional image tokens (denoted as `32000`), resulting in:
+        `[1, 3148, 1001, 29901, 29871, 32000, ..., 32000, 29871, 13, 5618,
+        29915, 29879, 278, 2793, 310, 278, 1967, 29973, 13, 22933, 9047, 13566,
+        29901]`.
+
+        We insert 575 tokens so that including the original image token in the
+        input, there are a total of 576 (24 * 24) image tokens, which
+        corresponds to the number of image tokens inputted to the language
+        model, i.e. the number of image tokens outputted by the visual encoder.
+
+        This way, the `positions` and `attn_metadata` are consistent
+        with the `input_ids`.
+
+        Args:
+            input_ids: Flattened (concatenated) input_ids corresponding to a
+                batch.
+            pixel_values: The pixels in each input image.

+    on relative position of the query and key. It is HxNxN, where H is the 
+    number of heads, N is the sequence length.
+
+    I've made these modifications to the original T5 bias:
+    - Skipping of the bucketing step. Original T5 bias converted rel 
+      position distances into logarithmically increasing buckets. This is 
+      supposed to help with length generalization.
+    - I just directly use rel position index as bias values, as we don't 
+      need length generalization (40s max is good enough for ASR encoder), 
+      and it keeps ONNX export simple.
+    - I've also extended it so that biases can be asymmetric, the default 
+      implementation treats L->R and R->L the same. Asymmetric was found to 
+      yield better results in my experiments.

+This file implements common components for MLA implementations.
+
+First we define:
+
+Sq      as Q sequence length
+Skv     as KV sequence length
+
+MLA has two possible ways of computing, a data-movement friendly approach and a
+compute friendly approach, we generally want to use the compute friendly
+approach for "prefill" (i.e. the ratio Sq / Skv is "small", is near 1)
+and the data-movement friendly approach for "decode" (i.e. the ratio
+Sq / Skv is "large").
+
+NOTE what we deem small and large is currently determined by if its labelled
+prefill or decode by the scheduler, but this is something we should probably
+tune.
+
+Main reference: DeepseekV2 paper, and FlashInfer Implementation
+(https://arxiv.org/abs/2405.04434 and https://github.com/flashinfer-ai/flashinfer/pull/551).
+
+Deepseek's MLA attention works the following way:
+* Use a single latent vector to represent the per-token entry of the KV cache. 
+* For decode (i.e. the memory friendly approach) the attention "simulates" a
+multi-head attention, while the compute is similar to multi-query attention.
+
+Below is example of both paths assuming batchsize = 1

+## Chunked Prefill
+
+For chunked prefill we want to use the compute friendly algorithm. We are 
+assuming sufficiently large Sq / Skv ratio, in the future may want to switch to 
+the data-movement friendly approach if the chunk (i.e. `Sq`) is small.
+
+However, the compute-friendly approach can potentially run out of memory if Skv
+is large due to: `k_nope = (kv_c @ W_UK).view(Skv, N, P)`
+
+To mitigate this, we chunk the computation of attention with respect to the 
+current context (i.e. `cache_kv_c` and `cache_k_pe`) so that we can used a 
+fixed workspace size.
+
+The chunked prefill approach is as follows:
+
+MCC        Max chunk of context to process per iter, computed dynamically, 
+           used to bound the memory usage
