# Change Log for SD.Next
## Update for 2026-03-23
### Highlights for 2026-03-23
This release brings massive code refactoring to modernize codebase and removal of some obsolete features. Leaner & Faster!
And since its a bit quieter period when it comes to new models, notable additions would be : *FireRed-Image-Edit* *SkyWorks-UniPic-3* and *Anima-Preview-2*
If you're on Windows platform, we have a brand new [All-in-one Installer & Launcher](https://github.com/vladmandic/sdnext-launcher): simply download [exe or zip](https://github.com/vladmandic/sdnext-launcher/releases) and done!
*What else*? Really a lot!
New color grading module, updated localization with new languages and improved translations, new civitai integration module, new finetunes loader, several new upscalers, improvements to LLM/VLM in captioning and prompt enhance, a lot of new control preprocessors, new realtime server info panel, some new UI themes
And major work on API hardening: security, rate limits, secrets handling, new endpoints, etc.
But also many smaller quality-of-life improvements - for full details, see [ChangeLog](https://github.com/vladmandic/automatic/blob/master/CHANGELOG.md)

### Details for 2025-10-17
- **Models**
- [WAN 2.2 14B VACE](https://huggingface.co/alibaba-pai/Wan2.2-VACE-Fun-A14B)
available for *text-to-image* and *text-to-video* and *image-to-video* workflows
- [Qwen Image Edit 2509](https://huggingface.co/Qwen/Qwen-Image-Edit-2509) and [Nunchaku Qwen Image Edit 2509](https://huggingface.co/nunchaku-tech/nunchaku-qwen-image-edit-2509)
updated version of Qwen Image Edit with improved image consistency
- [Qwen Image Pruning](https://huggingface.co/OPPOer/Qwen-Image-Pruning) and [Qwen Image Edit Pruning](https://huggingface.co/OPPOer/Qwen-Image-Edit-Pruning)
pruned versions of Qwen with 13B params instead of 20B, with some quality tradeoff
- [Tencent FLUX.1 Dev SRPO](https://huggingface.co/tencent/SRPO)
SRPO is trained by Tencent with specific technique: directly aligning the full diffusion trajectory with fine-grained human preference
- [Nunchaku SDXL](https://huggingface.co/nunchaku-tech/nunchaku-sdxl) and [Nunchaku SDXL Turbo](https://huggingface.co/nunchaku-tech/nunchaku-sdxl-turbo)
impact of nunchaku engine on unet-based model such as sdxl is much less than on a dit-based models, but its still significantly faster than baseline
note that nunchaku optimized and pre-quantized unet is replacement for base unet, so its only applicable to base models, not any of fine-tunes
*how to use*: enable nunchaku in settings -> quantization and then load either sdxl-base or sdxl-base-turbo reference models
- [HiDream E1.1](https://huggingface.co/HiDream-ai/HiDream-E1-1)
updated version of HiDream-E1 image editing model
- [LTXVideo 0.9.8](https://huggingface.co/Lightricks/LTX-Video-0.9.8-13B-distilled)
updated version of LTXVideo t2v/i2iv model
- [SeedVR2](https://iceclear.github.io/projects/seedvr/)
originally designed for video restoration, seedvr works great for image detailing and upscaling!
available in 3B, 7B and 7B-sharp variants, use as any other upscaler!
note: seedvr is a very large model (6.4GB and 16GB respectively) and not designed for lower-end hardware, quantization is highly recommended
note: seedvr is highly sensitive to its cfg scale, set in *settings -> postprocessing*
lower values will result in smoother output while higher values add details
- [X-Omni SFT](https://x-omni-team.github.io/)
*experimental*: X-omni is a transformer-only discrete auto-regressive image generative model trained with reinforcement learning
- **Features**
- **Model save**: ability to save currently loaded model as a new standalone model
why? SD.Next always prefers to start with full model and quantize on-demand during load
however, when you find your exact preferred quantization settings that work well for you,
saving such model as a new model allows for faster loads and reduced disk space usage
so its best of both worlds: you can experiment and test different quantization methods and once you find the one that works for you, save it as a new model
saved models appear in network tab as normal models and can be loaded as such
available in *models* tab
- [Qwen Image-Edit](https://huggingface.co/Qwen/Qwen-Image-Edit-2509) multi-image editing
requires qwen-image-edit-2509 or its variant as multi-image edits are not available in original qwen-image
in ui control tab: inputs -> separate init image
add image for *input media* and *control media*
can be
- [Cache-DiT](https://github.com/vipshop/cache-dit)

compatible with many dit-based models such as FLUX.1, Qwen, HunyuanImage, Wan2.2, Chroma, etc.
enable in *settings -> pipeline modifiers -> cache-dit*
- [Nunchaku Flux.1 PulID](https://nunchaku.tech/docs/nunchaku/python_api/nunchaku.pipeline.pipeline_flux_pulid.html)
automatically enabled if loaded model is FLUX.1 with Nunchaku engine enabled and when PulID script is enabled

for example enter, `https://hf-mirror.com`
- **Compute**
- **ROCm** for Windows
support for both official torch preview release of `torch-rocm` for windows and **TheRock** unofficial `torch-rocm` builds for windows
note that rocm for windows is still in preview and has limited gpu support, please check rocm docs for details
- **DirectML** warn as *end-of-life*
`torch-directml` received no updates in over 1 year and its currently superseded by `rocm` or `zluda`
- command line params `--use-zluda` and `--use-rocm` will attempt desired operation or fail if not possible
previously sdnext was performing a fallback to `torch-cpu` which is not desired
- **installer** if `--use-cuda` or `--use-rocm` are specified and `torch-cpu` is installed, installer will attempt to reinstall correct torch package
- **installer** warn if *cuda* or *rocm* are available and `torch-cpu` is installed
- support for `torch==2.10-nightly` with `cuda==13.0`
- **Extensions**
- [Agent-Scheduler](https://github.com/SipherAGI/sd-webui-agent-scheduler)
was a high-value built-in extension, but it has not been maintained for 1.5 years
it also does not work with control and video tabs which are the core of sdnext nowadays
so it has been removed from built-in extensions: manual installation is still possible
- [DAAM: Diffusion Attentive Attribution Maps](https://github.com/castorini/daam)
create heatmap visualizations of which parts of the prompt influenced which parts of the image
available in scripts for sdxl text-to-image workflows

## Update for 2025-09-15
### Highlights for 2025-09-15
*What's new*? Big one is that we're (*finally*) switching the default UI to **ModernUI**, for both desktop and mobile use!
**StandardUI** is still available and can be selected in settings, but ModernUI is now the default for new installs
*What's else*? **Chroma** is in its final form, there are several new **Qwen-Image** variants and **Nunchaku** hit version 1.0!
Also, there are quite a few offloading improvements and many quality-of-life changes to UI and overall workflows
And check out new **history** tab in the right panel, it now shows visualization of entire processing timeline!

- **Qwen-Image** [InstantX ControlNet Union](https://huggingface.co/InstantX/Qwen-Image-ControlNet-Union) support
*note* qwen-image is already a very large model and controlnet adds 3.5GB on top of that so quantization and offloading are highly recommended!
- [Qwen-Lightning-Edit](https://huggingface.co/vladmandic/Qwen-Lightning-Edit) and [Qwen-Image-Distill](https://huggingface.co/SahilCarterr/Qwen-Image-Distill-Full) variants

- **Nunchaku** variant of [Flux.1-Krea-Dev](https://huggingface.co/nunchaku-tech/nunchaku-flux.1-krea-dev)
if you have a compatible nVidia GPU, Nunchaku is the fastest quantization & inference engine
- [HunyuanDiT ControlNet](https://huggingface.co/Tencent-Hunyuan/HYDiT-ControlNet-v1.2) Canny, Depth, Pose
- [KBlueLeaf/HDM-xut-340M-anime](https://huggingface.co/KBlueLeaf/HDM-xut-340M-anime)
highly experimental: HDM *Home-made-Diffusion-Model* is a project to investigate specialized training recipe/scheme
for pre-training T2I model at home based on super-light architecture
*requires*: generator=cpu, dtype=float16, offload=none, both positive and negative prompts are required and must be long & detailed

## Update for 2025-07-29
### Highlights for 2025-07-29
This is a big one: simply looking at number of changes, probably the biggest release since the project started!
Feature highlights include:
- [ModernUI](https://github.com/user-attachments/assets/6f156154-0b0a-4be2-94f0-979e9f679501) has quite some redesign which should make it more user friendly and easier to navigate plus several new UI themes
If you're still using **StandardUI**, give [ModernUI](https://vladmandic.github.io/sdnext-docs/Themes/) a try!
- New models such as [WanAI 2.2](https://wan.video/) in 5B and A14B variants for both *text-to-video* and *image-to-video* workflows as well as *text-to-image* workflow!
and also [FreePik F-Lite](https://huggingface.co/Freepik/F-Lite), [Bria 3.2](https://huggingface.co/briaai/BRIA-3.2) and [bigASP 2.5](https://civitai.com/models/1789765?modelVersionId=2025412)
- Redesigned [Video](https://vladmandic.github.io/sdnext-docs/Video) interface with support for general video models plus optimized [FramePack](https://vladmandic.github.io/sdnext-docs/FramePack) and [LTXVideo](https://vladmandic.github.io/sdnext-docs/LTX) support
- Fully integrated nudity detection and optional censorship with [NudeNet](https://vladmandic.github.io/sdnext-docs/NudeNet)
- New background replacement and relightning methods using **Latent Bridge Matching** and new **PixelArt** processing filter
- Enhanced auto-detection of default sampler types/settings results in avoiding common mistakes
- Additional **LLM/VLM** models available for captioning and prompt enhance
- Number of workflow and general quality-of-life improvements, especially around **Styles**, **Detailer**, **Preview**, **Batch**, **Control**
- Compute improvements
- [Wiki](https://github.com/vladmandic/automatic/wiki) & [Docs](https://vladmandic.github.io/sdnext-docs/) updates, especially new end-to-end [Parameters](https://vladmandic.github.io/sdnext-docs/Parameters/) page
In this release we finally break with legacy with the removal of the original [A1111](https://github.com/AUTOMATIC1111/stable-diffusion-webui/) codebase which has not been maintained for a while now
This plus major cleanup of codebase and external dependencies resulted in ~55k LoC (*lines-of-code*) reduction and spread over [~750 files](https://github.com/vladmandic/sdnext/pull/4017) in ~200 commits!
We also switched project license to [Apache-2.0](https://github.com/vladmandic/sdnext/blob/dev/LICENSE.txt) which means that SD.Next is now fully compatible with commercial and non-commercial use and redistribution regardless of modifications!
And (*as always*) many bugfixes and improvements to existing features!
For details, see [ChangeLog](https://github.com/vladmandic/automatic/blob/master/CHANGELOG.md)
> [!NOTE]
> We recommend clean install for this release due to sheer size of changes
> Although upgrades and existing installations are tested and should work fine!

### Details for 2025-07-29
- **License**
- SD.Next [license](https://github.com/vladmandic/sdnext/blob/dev/LICENSE.txt) switched from **aGPL-v3.0** to **Apache-v2.0**
this means that SD.Next is now fully compatible with commercial and non-commercial use and redistribution regardless of modifications!
- **Models**
- [WanAI Wan 2.2](https://github.com/Wan-Video/Wan2.2) both 5B and A14B variants, for both T2V and I2V support
go to: *video -> generic -> wan -> pick variant*
optimized support with *VACE*, etc. will follow soon
*caution* Wan2.2 on its own is ~68GB, but also includes optional second-stage for later low-noise processing which is absolutely massive at additional ~54GB
you can enable second stage processing in *settings -> model options*, its disabled by default
*note*: quantization and offloading are highly recommended regardless of first-stage only or both stages!
- [WanAI Wan](https://wan.video/) T2V models for T2I workflows
Wan is originally designed for *video* workflows, but now also be used for *text-to-image* workflows!
supports *Wan-2.1 in 1.3B* and 14B variants and *Wan-2.2 in 5B and A14B* variants
supports all standard features such as quantization, offloading, TAESD preview generation, LoRA support etc.
can also load unet/transformer fine-tunes in safetensors format using UNET loader
simply select in *networks -> models -> reference*
*note* 1.3B model is a bit too small for good results and 14B is very large at 78GB even without second-stage so aggressive quantization and offloading are recommended
- [FreePik F-Lite](https://huggingface.co/Freepik/F-Lite) in *7B, 10B and Texture* variants
F-Lite is a 7B/10B model trained exclusively on copyright-safe and SFW content, trained on internal dataset comprising approximately 80 million copyright-safe images
available via *networks -> models -> reference*
- [Bria 3.2](https://huggingface.co/briaai/BRIA-3.2)
Bria is a smaller 4B parameter model built entirely on licensed data and safe for commercial use
*note*: this is a gated model, you need to [accept terms](https://huggingface.co/briaai/BRIA-3.2) and set your [huggingface token](https://vladmandic.github.io/sdnext-docs/Gated/)
available via *networks -> models -> reference*
- [bigASP 2.5](https://civitai.com/models/1789765)
bigASP is an experimental SDXL finetune using Flow matching method
load as usual, and leave sampler set to *Default*
or you can use following samplers: *UniPC, DPM, DEIS, SA*

- **Compute**
- support for [SageAttention2++](https://github.com/thu-ml/SageAttention)
provides 10-15% performance improvement over default SDPA for transformer-based models!
enable in *settings -> compute settings -> sdp options*
*note*: SD.Next will use either SageAttention v1/v2/v2++, depending which one is installed
until authors provide pre-build wheels for v2++, you need to install it manually or SD.Next will auto-install v1
- support for `torch.compile` for LLM: captioning/prompt-enhannce
- support for `torch.compile` with repeated-blocks
reduces time-to-compile 5x without loss of performance!
enable in *settings -> model compile -> repeated*
*note*: torch.compile is not compatible with balanced offload
- **Other**
- **Styles** can now include both generation params and server settings
see [Styles docs](https://vladmandic.github.io/sdnext-docs/Styles/) for details
- **TAESD** is now default preview type since its the only one that supports most new models
- support **TAESD** preview and remote VAE for **HunyuanDit**
- support **TAESD** preview and remote VAE for **AuraFlow**
- support **TAESD** preview for **WanAI**
- SD.Next now starts with *locked* state preventing model loading until startup is complete
- warn when modifying legacy settings that are no longer supported, but available for compatibilty
- warn on incompatible sampler and automatically restore default sampler
- **XYZ grid** can now work with control tab:
if controlnet or processor are selected in xyz grid, they will overwrite settings from first unit in control tab,
when using controlnet/processor selected in xyz grid, behavior is forced as control-only
also freely selectable are control strength, start and end values
- **Batch** warn on unprocessable images and skip operations on errors so that other images can still be processed
- **Metadata** improved parsing and detect foreign metadata
detect ComfyUI images
detect InvokeAI images
- **Detailer** add `expert` mode where list of detailer models can be converted to textbox for manual editing
see [docs](https://vladmandic.github.io/sdnext-docs/Detailer/) for more information
- **Detailer** add option to merge multiple results from each detailer model
for example, hands model can result in two hands each being processed separately or both hands can be merged into one composite job
- **Control** auto-update width/height on image upload
- **Control** auto-determine image save path depending on operations performed
- autodetect **V-prediction** models and override default sampler prediction type as needed
- **SDNQ**
- use inference context during quantization
- use static compile
- rename quantization type for text encoders `default` option to `Same as model`
- **API**
- add `/sdapi/v1/lock-checkpoint` endpoint that can be used to lock/unlock model changes
if model is locked, it cannot be changed using normal load or unload methods
