Deploy this version​

docker run litellm

-p 4000:4000
ghcr.io/berriai/litellm:main-v1.71.1-stable

Key Highlights​

LiteLLM v1.71.1-stable is live now. Here are the key highlights of this release:

  • Performance improvements: LiteLLM can now scale to 200 RPS per instance with a 74ms median response time.
  • File Permissions: Control file access across OpenAI, Azure, VertexAI.
  • MCP x OpenAI: Use MCP servers with OpenAI Responses API.

Performance Improvements​


This release brings aiohttp support for all LLM api providers. This means that LiteLLM can now scale to 200 RPS per instance with a 40ms median latency overhead.

This change doubles the RPS LiteLLM can scale to at this latency overhead.

You can opt into this by enabling the flag below. (We expect to make this the default in 1 week.)

Flag to enable​

On LiteLLM Proxy

Set the USE_AIOHTTP_TRANSPORT=True in the environment variables.

Environment Variable
export USE_AIOHTTP_TRANSPORT="True"

On LiteLLM Python SDK

Set the use_aiohttp_transport=True to enable aiohttp transport.

Python SDK
import litellm

litellm.use_aiohttp_transport = True # default is False, enable this to use aiohttp transport
result = litellm.completion(
    model="openai/gpt-4o",
    messages=[{"role": "user", "content": "Hello, world!"}],
)
print(result)

File Permissions​


This release brings support for File Permissions and Finetuning APIs to LiteLLM Managed Files. This is great for:

  • Proxy Admins: as users can only view/edit/delete files they’ve created - even when using shared OpenAI/Azure/Vertex deployments.
  • Developers: get a standard interface to use Files across Chat/Finetuning/Batch APIs.
