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.

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

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.

v1.65.4-stable is live. Here are the improvements since v1.65.0-stable.

Key Highlights​

  • Preventing DB Deadlocks: Fixes a high-traffic issue when multiple instances were writing to the DB at the same time.
  • New Usage Tab: Enables viewing spend by model and customizing date range

Let's dive in.

Preventing DB Deadlocks​

This release fixes the DB deadlocking issue that users faced in high traffic (10K+ RPS). This is great because it enables user/key/team spend tracking works at that scale.

Read more about the new architecture here

New Usage Tab​

The new Usage tab now brings the ability to track daily spend by model. This makes it easier to catch any spend tracking or token counting errors, when combined with the ability to view successful requests, and token usage.

To test this out, just go to Experimental > New Usage > Activity.

v1.65.0-stable is live now. Here are the key highlights of this release:

  • MCP Support: Support for adding and using MCP servers on the LiteLLM proxy.
  • UI view total usage after 1M+ logs: You can now view usage analytics after crossing 1M+ logs in DB.

Model Context Protocol (MCP)​

This release introduces support for centrally adding MCP servers on LiteLLM. This allows you to add MCP server endpoints and your developers can list and call MCP tools through LiteLLM.

Read more about MCP here.

Expose and use MCP servers through LiteLLM

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' \

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 

general_settings:
  store_prompts_in_spend_logs: true

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

Start Here

docker image, security, vulnerability

0 Critical/High Vulnerabilities

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

Deepgram Speech to Text​

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)
