+### Assistants v2 (preview)
+
+A refresh of the Assistants API is now publicly available. It contains the following updates:
+
+* [File search tool and vector storage](./how-to/file-search.md)
+* [Max completion and max prompt token support](./concepts/assistants.md#context-window-management) for managing token usage.
+* `tool_choice` [parameter](./assistants-reference-runs.md#run-object) for forcing the Assistant to use use a specified tool. 
+You can now create messages with the [assistant](.//assistants-reference-messages.md#create-message) role to create custom conversation histories in Threads.
+* Support for `temperature`, `top_p`, `response_format` [parameters](./assistants-reference.md#create-an-assistant).
+* Streaming and polling support. You can use the helper functions in our Python SDK to create runs and stream responses. We have also added polling SDK helpers to share object status updates without the need for polling. 
+* Experiment with Logic Apps and Function Calling using Azure OpenAI Studio. Import your REST APIs implemented in Logic Apps as functions and the studio invokes the function (as a Logic Apps workflow) automatically based on the user prompt.
+* AutoGen by Microsoft Research provides a multi-agent conversation framework to enable convenient building of Large Language Model (LLM) workflows across a wide range of applications. Azure OpenAI assistants are now integrated into AutoGen via `GPTAssistantAgent`, a new experimental agent that lets you seamlessly add Assistants into AutoGen-based multi-agent workflows. This enables multiple Azure OpenAI assistants, that could be task or domain specialized, to collaborate and tackle complex tasks.
+* Support for fine-tuned `gpt-3.5-turbo-0125` [models](./concepts/models.md#assistants-preview) in the following regions:
+    * East US 2
+    * Sweden Central
+* Expanded regional support for:
+    * Japan East
+    * UK South
+    * West US
+    * West US 3

+### GPT-4o model general availability (GA)
+
+GPT-4o ("o is for "omni") is the latest model from OpenAI launched on May 13, 2024.
+
+- GPT-4o integrates text, and images in a single model, enabling it to handle multiple data types simultaneously. This multimodal approach enhances accuracy and responsiveness in human-computer interactions.
+- GPT-4o matches GPT-4 Turbo in English text and coding tasks while offering superior performance in non-English languages and in vision tasks, setting new benchmarks for AI capabilities.
+
+For information on model regional availability, see the [models page](./concepts/models.md).
+
+### Global standard deployment type (Preview)
+
+Global deployments are available in the same Azure OpenAI resources as non-global offers but allow you to leverage Azure's global infrastructure to dynamically route traffic to the data center with best availability for each request. Global standard will provide the highest default quota for new models and eliminates the need to load balance across multiple resources.
+
+For more information, see the [deployment types guide](https://aka.ms/aoai/docs/deployment-types).
+
+### Fine-tuning updates
+
+- GPT-4 fine-tuning is [now available](./concepts/models.md#fine-tuning-models).
+- Added support for seed, events, full validation statistics, and checkpoints as part of the `2024-05-01-preview` API release.
+
+### 2024-05-01-preview API release
+
+- For more information, see the [API version lifecycle](./api-version-deprecation.md).
