  • Major Changes
    • User Agent will be auto-tracked as a tag in LiteLLM UI Logs Page. This means for all LLM requests you will see a User Agent tag in the logs page.

Key Highlights​

Set Default Team for New Users​


v1.73.0 introduces the ability to assign new users to Default Teams. This makes it much easier to enable experimentation with LLMs within your company, while also ensuring spend for exploration is tracked correctly.

What this means for Proxy Admins:

  • Set a max budget per team member: This sets a max amount an individual can spend within a team.
  • Set a default team for new users: When a new user signs in via SSO / invitation link, they will be automatically added to this team.

What this means for Developers:

  • View models across teams: You can now go to Models + Endpoints and view the models you have access to, across all teams you're a member of.
  • Safe create key modal: If you have no model access outside of a team (default behaviour), you are now nudged to select a team on the Create Key modal. This resolves a common confusion point for new users onboarding to the proxy.

Get Started

Passthrough Endpoints v2​


This release brings support for adding billing and full URL forwarding for passthrough endpoints.

Previously, you could only map simple endpoints, but now you can add just /bria and all subroutes automatically get forwarded - for example, /bria/v1/text-to-image/base/model and /bria/v1/enhance_image will both be forwarded to the target URL with the same path structure.

This means you as Proxy Admin can onboard third-party endpoints like Bria API and Mistral OCR, set a cost per request, and give your developers access to the complete API functionality.

Learn more about Passthrough Endpoints

v2 Health Checks​


This release brings support for Proxy Admins to select which specific models to health check and see the health status as soon as its individual check completes, along with last check times.

This allows Proxy Admins to immediately identify which specific models are in a bad state and view the full error stack trace for faster troubleshooting.

ghcr.io/berriai/litellm:main-v1.72.6-stable

TLDR​

  • Why Upgrade
    • Codex-mini on Claude Code: You can now use codex-mini (OpenAI’s code assistant model) via Claude Code.
    • MCP Permissions Management: Manage permissions for MCP Servers by Keys, Teams, Organizations (entities) on LiteLLM.
    • UI: Turn on/off auto refresh on logs view.
    • Rate Limiting: Support for output token-only rate limiting.
  • Who Should Read
    • Teams using /v1/messages API (Claude Code)
    • Teams using MCP
    • Teams giving access to self-hosted models and setting rate limits
  • Risk of Upgrade
    • Low
      • No major changes to existing functionality or package updates.

Key Highlights​

MCP Permissions Management​

This release brings support for managing permissions for MCP Servers by Keys, Teams, Organizations (entities) on LiteLLM. When a MCP client attempts to list tools, LiteLLM will only return the tools the entity has permissions to access.

This is great for use cases that require access to restricted data (e.g Jira MCP) that you don't want everyone to use.

For Proxy Admins, this enables centralized management of all MCP Servers with access control. For developers, this means you'll only see the MCP tools assigned to you.

Codex-mini on Claude Code​

This release brings support for calling codex-mini (OpenAI’s code assistant model) via Claude Code.

This is done by LiteLLM enabling any Responses API model (including o3-pro) to be called via /chat/completions and /v1/messages endpoints. This includes:

  • Streaming calls
  • Non-streaming calls
  • Cost Tracking on success + failure for Responses API models

Here's how to use it today

ghcr.io/berriai/litellm:main-v1.72.2-stable

TLDR​

  • Why Upgrade
    • Performance Improvements for /v1/messages: For this endpoint LiteLLM Proxy overhead is now down to 50ms at 250 RPS.
    • Accurate Rate Limiting: Multi-instance rate limiting now tracks rate limits across keys, models, teams, and users with 0 spillover.
    • Audit Logs on UI: Track when Keys, Teams, and Models were deleted by viewing Audit Logs on the LiteLLM UI.
    • /v1/messages all models support: You can now use all LiteLLM models (gpt-4.1, o1-pro, gemini-2.5-pro) with /v1/messages API.
    • Anthropic MCP: Use remote MCP Servers with Anthropic Models.
  • Who Should Read
    • Teams using /v1/messages API (Claude Code)
    • Proxy Admins using LiteLLM Virtual Keys and setting rate limits
  • Risk of Upgrade
    • Medium
      • Upgraded ddtrace==3.8.0, if you use DataDog tracing this is a medium level risk. We recommend monitoring logs for any issues.

/v1/messages Performance Improvements​

This release brings significant performance improvements to the /v1/messages API on LiteLLM.

For this endpoint LiteLLM Proxy overhead latency is now down to 50ms, and each instance can handle 250 RPS. We validated these improvements through load testing with payloads containing over 1,000 streaming chunks.

This is great for real time use cases with large requests (eg. multi turn conversations, Claude Code, etc.).

Multi-Instance Rate Limiting Improvements​

LiteLLM now accurately tracks rate limits across keys, models, teams, and users with 0 spillover.

This is a significant improvement over the previous version, which faced issues with leakage and spillover in high traffic, multi-instance setups.

Key Changes:

  • Redis is now part of the rate limit check, instead of being a background sync. This ensures accuracy and reduces read/write operations during low activity.
  • LiteLLM now uses Lua scripts to ensure all checks are atomic.
  • In-memory caching uses Redis values. This prevents drift, and reduces Redis queries once objects are over their limit.

These changes are currently behind the feature flag - EXPERIMENTAL_ENABLE_MULTI_INSTANCE_RATE_LIMITING=True. We plan to GA this in our next release - subject to feedback.

Audit Logs on UI​

This release introduces support for viewing audit logs in the UI. As a Proxy Admin, you can now check if and when a key was deleted, along with who performed the action.

LiteLLM tracks changes to the following entities and actions:

  • Entities: Keys, Teams, Users, Models
  • Actions: Create, Update, Delete, Regenerate

Ishaan Jaffer
CTO, LiteLLM

Deploy this version​

docker run litellm
docker run
-e STORE_MODEL_IN_DB=True
-p 4000:4000
ghcr.io/berriai/litellm:main-v1.72.0-stable

Key Highlights​

LiteLLM v1.72.0-stable.rc is live now. Here are the key highlights of this release:

  • Vector Store Permissions: Control Vector Store access at the Key, Team, and Organization level.
  • Rate Limiting Sliding Window support: Improved accuracy for Key/Team/User rate limits with request tracking across minutes.
  • Aiohttp Transport used by default: Aiohttp transport is now the default transport for LiteLLM networking requests. This gives users 2x higher RPS per instance with a 40ms median latency overhead.
  • Bedrock Agents: Call Bedrock Agents with /chat/completions, /response endpoints.
  • Anthropic File API: Upload and analyze CSV files with Claude-4 on Anthropic via LiteLLM.
  • Prometheus: End users (end_user) will no longer be tracked by default on Prometheus. Tracking end_users on prometheus is now opt-in. This is done to prevent the response from /metrics from becoming too large. Read More

Vector Store Permissions​

This release brings support for managing permissions for vector stores by Keys, Teams, Organizations (entities) on LiteLLM. When a request attempts to query a vector store, LiteLLM will block it if the requesting entity lacks the proper permissions.

This is great for use cases that require access to restricted data that you don't want everyone to use.

Over the next week we plan on adding permission management for MCP Servers.

Aiohttp Transport used by default​

Aiohttp transport is now the default transport for LiteLLM networking requests. This gives users 2x higher RPS per instance with a 40ms median latency overhead. This has been live on LiteLLM Cloud for a week + gone through alpha users testing for a week.

If you encounter any issues, you can disable using the aiohttp transport in the following ways:

On LiteLLM Proxy

Set the DISABLE_AIOHTTP_TRANSPORT=True in the environment variables.

Environment Variable
export DISABLE_AIOHTTP_TRANSPORT="True"

On LiteLLM Python SDK

Set the disable_aiohttp_transport=True to disable aiohttp transport.

Python SDK
import litellm

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

Ishaan Jaffer
Ishaan Jaffer
CTO, LiteLLM

Deploy this version​

docker run litellm
docker run
-e STORE_MODEL_IN_DB=True
-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.

docker run litellm
docker run
-e STORE_MODEL_IN_DB=True
-p 4000:4000
ghcr.io/berriai/litellm:main-v1.70.1-stable

Key Highlights​

LiteLLM v1.70.1-stable is live now. Here are the key highlights of this release:

  • Gemini Realtime API: You can now call Gemini's Live API via the OpenAI /v1/realtime API
  • Spend Logs Retention Period: Enable deleting spend logs older than a certain period.
  • PII Masking 2.0: Easily configure masking or blocking specific PII/PHI entities on the UI

Gemini Realtime API​

This release brings support for calling Gemini's realtime models (e.g. gemini-2.0-flash-live) via OpenAI's /v1/realtime API. This is great for developers as it lets them easily switch from OpenAI to Gemini by just changing the model name.

Key Highlights:

  • Support for text + audio input/output
  • Support for setting session configurations (modality, instructions, activity detection) in the OpenAI format
  • Support for logging + usage tracking for realtime sessions

This is currently supported via Google AI Studio. We plan to release VertexAI support over the coming week.

Spend Logs Retention Period​

This release enables deleting LiteLLM Spend Logs older than a certain period. Since we now enable storing the raw request/response in the logs, deleting old logs ensures the database remains performant in production.

PII Masking 2.0​

This release brings improvements to our Presidio PII Integration. As a Proxy Admin, you now have the ability to:

  • Mask or block specific entities (e.g., block medical licenses while masking other entities like emails).
  • Monitor guardrails in production. LiteLLM Logs will now show you the guardrail run, the entities it detected, and its confidence score for each entity.

Deploy this version​

docker run litellm
docker run
-e STORE_MODEL_IN_DB=True
-p 4000:4000
ghcr.io/berriai/litellm:main-v1.69.0-stable

Key Highlights​

LiteLLM v1.69.0-stable brings the following key improvements:

  • Loadbalance Batch API Models: Easily loadbalance across multiple azure batch deployments using LiteLLM Managed Files
  • Email Invites 2.0: Send new users onboarded to LiteLLM an email invite.
  • Nscale: LLM API for compliance with European regulations.
  • Bedrock /v1/messages: Use Bedrock Anthropic models with Anthropic's /v1/messages.

Batch API Load Balancing​

This release brings LiteLLM Managed File support to Batches. This is great for:

  • Proxy Admins: You can now control which Batch models users can call.
  • Developers: You no longer need to know the Azure deployment name when creating your batch .jsonl files - just specify the model your LiteLLM key has access to.

Over time, we expect LiteLLM Managed Files to be the way most teams use Files across /chat/completions, /batch, /fine_tuning endpoints.

Email Invites​

This release brings the following improvements to our email invite integration:

  • New templates for user invited and key created events.
  • Fixes for using SMTP email providers.
  • Native support for Resend API.

Deploy this version​

docker run litellm
docker run
-e STORE_MODEL_IN_DB=True
-p 4000:4000
ghcr.io/berriai/litellm:main-v1.68.0-stable

Key Highlights​

LiteLLM v1.68.0-stable will be live soon. Here are the key highlights of this release:

  • Bedrock Knowledge Base: You can now call query your Bedrock Knowledge Base with all LiteLLM models via /chat/completion or /responses API.
  • Rate Limits: This release brings accurate rate limiting across multiple instances, reducing spillover to at most 10 additional requests in high traffic.
  • Meta Llama API: Added support for Meta Llama API Get Started
  • LlamaFile: Added support for LlamaFile Get Started

Bedrock Knowledge Base (Vector Store)​


This release adds support for Bedrock vector stores (knowledge bases) in LiteLLM. With this update, you can:

  • Use Bedrock vector stores in the OpenAI /chat/completions spec with all LiteLLM supported models.
  • View all available vector stores through the LiteLLM UI or API.
  • Configure vector stores to be always active for specific models.
  • Track vector store usage in LiteLLM Logs.

For the next release we plan on allowing you to set key, user, team, org permissions for vector stores.

Read more here

Rate Limiting​


This release brings accurate multi-instance rate limiting across keys/users/teams. Outlining key engineering changes below:

  • Change: Instances now increment cache value instead of setting it. To avoid calling Redis on each request, this is synced every 0.01s.
  • Accuracy: In testing, we saw a maximum spill over from expected of 10 requests, in high traffic (100 RPS, 3 instances), vs. current 189 request spillover
  • Performance: Our load tests show this to reduce median response time by 100ms in high traffic 

This is currently behind a feature flag, and we plan to have this be the default by next week. To enable this today, just add this environment variable:

export LITELLM_RATE_LIMIT_ACCURACY=true

Ishaan Jaffer
CTO, LiteLLM

Deploy this version​

docker run litellm
docker run
-e STORE_MODEL_IN_DB=True
-p 4000:4000
ghcr.io/berriai/litellm:main-v1.67.4-stable

Key Highlights​

  • Improved User Management: This release enables search and filtering across users, keys, teams, and models.
  • Responses API Load Balancing: Route requests across provider regions and ensure session continuity.
  • UI Session Logs: Group several requests to LiteLLM into a session.

Improved User Management​


This release makes it easier to manage users and keys on LiteLLM. You can now search and filter across users, keys, teams, and models, and control user settings more easily.

New features include:

  • Search for users by email, ID, role, or team.
  • See all of a user's models, teams, and keys in one place.
  • Change user roles and model access right from the Users Tab.

These changes help you spend less time on user setup and management on LiteLLM.

Responses API Load Balancing​


This release introduces load balancing for the Responses API, allowing you to route requests across provider regions and ensure session continuity. It works as follows:

  • If a previous_response_id is provided, LiteLLM will route the request to the original deployment that generated the prior response — ensuring session continuity.
  • If no previous_response_id is provided, LiteLLM will load-balance requests across your available deployments.

UI Session Logs​


This release allow you to group requests to LiteLLM proxy into a session. If you specify a litellm_session_id in your request LiteLLM will automatically group all logs in the same session. This allows you to easily track usage and request content per session.

UI view total usage after 1M+ logs​

This release brings the ability to view total usage analytics even after exceeding 1M+ logs in your database. We've implemented a scalable architecture that stores only aggregate usage data, resulting in significantly more efficient queries and reduced database CPU utilization.

View total usage after 1M+ logs

  • How this works:

    • We now aggregate usage data into a dedicated DailyUserSpend table, significantly reducing query load and CPU usage even beyond 1M+ logs.

  • Daily Spend Breakdown API:

    • Retrieve granular daily usage data (by model, provider, and API key) with a single endpoint. Example Request:
    Daily Spend Breakdown API
    curl -L -X GET 'http://localhost:4000/user/daily/activity?start_date=2025-03-20&end_date=2025-03-27' \
    -H 'Authorization: Bearer sk-...'

v1.65.0 - Team Model Add - update

Krrish Dholakia
Krrish Dholakia
CEO, LiteLLM
Ishaan Jaffer
Ishaan Jaffer
CTO, LiteLLM

v1.65.0 updates the /model/new endpoint to prevent non-team admins from creating team models.

This means that only proxy admins or team admins can create team models.

Additional Changes​

  • Allows team admins to call /model/update to update team models.
  • Allows team admins to call /model/delete to delete team models.
  • Introduces new user_models_only param to /v2/model/info - only return models added by this user.

These changes enable team admins to add and manage models for their team on the LiteLLM UI + API.

UI Improvements​

[Opt In] Admin UI - view messages / responses​

You can now view messages and response logs on Admin UI.

How to enable it - add store_prompts_in_spend_logs: true to your proxy_config.yaml

Once this flag is enabled, your messages and responses will be stored in the LiteLLM_Spend_Logs table.

general_settings:
  store_prompts_in_spend_logs: true

DB Schema Change​

Added messages and responses to the LiteLLM_Spend_Logs table.

By default this is not logged. If you want messages and responses to be logged, you need to opt in with this setting

Langfuse Prompt Management​

Langfuse Prompt Management is being labelled as BETA. This allows us to iterate quickly on the feedback we're receiving, and making the status clearer to users. We expect to make this feature to be stable by next month (February 2025).

Changes:

  • Include the client message in the LLM API Request. (Previously only the prompt template was sent, and the client message was ignored).
  • Log the prompt template in the logged request (e.g. to s3/langfuse).
  • Log the 'prompt_id' and 'prompt_variables' in the logged request (e.g. to s3/langfuse).

Start Here

Team/Organization Management + UI Improvements​

Managing teams and organizations on the UI is now easier.

Changes:

  • Support for editing user role within team on UI.
  • Support updating team member role to admin via api - /team/member_update
  • Show team admins all keys for their team.
  • Add organizations with budgets
  • Assign teams to orgs on the UI
  • Auto-assign SSO users to teams

Start Here

Hashicorp Vault Support​

We now support writing LiteLLM Virtual API keys to Hashicorp Vault.

Start Here

Custom Prometheus Metrics​

Define custom prometheus metrics, and track usage/latency/no. of requests against them

This allows for more fine-grained tracking - e.g. on prompt template passed in request metadata

docker image, security, vulnerability

What changed?​

  • LiteLLMBase image now uses cgr.dev/chainguard/python:latest-dev

Why the change?​

To ensure there are 0 critical/high vulnerabilities on LiteLLM Docker Image

Migration Guide​

  • If you use a custom dockerfile with litellm as a base image + apt-get

Instead of apt-get use apk, the base litellm image will no longer have apt-get installed.

You are only impacted if you use apt-get in your Dockerfile

# Use the provided base image
FROM ghcr.io/berriai/litellm:main-latest

# Set the working directory
WORKDIR /app

# Install dependencies - CHANGE THIS to `apk`
RUN apt-get update && apt-get install -y dumb-init

Before Change

RUN apt-get update && apt-get install -y dumb-init

After Change

RUN apk update && apk add --no-cache dumb-init

New Speech to Text support for Deepgram models. Start Here

from litellm import transcription
import os 

# set api keys 
os.environ["DEEPGRAM_API_KEY"] = ""
audio_file = open("/path/to/audio.mp3", "rb")

response = transcription(model="deepgram/nova-2", file=audio_file)

print(f"response: {response}")

Fireworks AI - Vision support for all models​

LiteLLM supports document inlining for Fireworks AI models. This is useful for models that are not vision models, but still need to parse documents/images/etc. LiteLLM will add #transform=inline to the url of the image_url, if the model is not a vision model See Code

Proxy Admin UI​

  • Test Key Tab displays model used in response
  • Test Key Tab renders content in .md, .py (any code/markdown format)
