ghcr.io/berriai/litellm:v1.77.7.rc.1

pip install litellm==1.77.7.rc.1

Key Highlights​

• Dynamic Rate Limiter v3 - Automatically maximizes throughput when capacity is available (< 80% saturation) by allowing lower-priority requests to use unused capacity, then switches to fair priority-based allocation under high load (≥ 80%) to prevent blocking
• Major Performance Improvements - 2.9x lower median latency at 1,000 concurrent users.
• Claude Sonnet 4.5 - Support for Anthropic's new Claude Sonnet 4.5 model family with 200K+ context and tiered pricing
• MCP Gateway Enhancements - Fine-grained tool control, server permissions, and forwardable headers
• AMD Lemonade & Nvidia NIM - New provider support for AMD Lemonade and Nvidia NIM Rerank
• GitLab Prompt Management - GitLab-based prompt management integration

Performance - 2.9x Lower Median Latency​

This update removes LiteLLM router inefficiencies, reducing complexity from O(M×N) to O(1). Previously, it built a new array and ran repeated checks like data["model"] in llm_router.get_model_ids(). Now, a direct ID-to-deployment map eliminates redundant allocations and scans.

As a result, performance improved across all latency percentiles:

• Median latency: 320 ms → 110 ms (−65.6%)
• p95 latency: 850 ms → 440 ms (−48.2%)
• p99 latency: 1,400 ms → 810 ms (−42.1%)
• Average latency: 864 ms → 310 ms (−64%)

Key Highlights​

• MCP OAuth 2.0 Support - Enhanced authentication for Model Context Protocol integrations
• Scheduled Key Rotations - Automated key rotation capabilities for enhanced security
• New Gemini 2.5 Flash & Flash-lite Models - Latest September 2025 preview models with improved pricing and features
• Performance Improvements - 54% RPS improvement

Scheduled Key Rotations​

This release brings support for scheduling virtual key rotations on LiteLLM AI Gateway.

This is great for Proxy Admins looking to enforce Enterprise Grade security for use cases going through LiteLLM AI Gateway.

From this release you can enforce Virtual Keys to rotate on a schedule of your choice e.g every 15 days/30 days/60 days etc.

Performance Improvements - 54% RPS Improvement​

This release brings a 54% RPS improvement (1,040 → 1,602 RPS, aggregated) per instance.

The improvement comes from fixing O(n²) inefficiencies in the LiteLLM Router, primarily caused by repeated use of in statements inside loops over large arrays.

Tests were run with a database-only setup (no cache hits).

Test Setup​

All benchmarks were executed using Locust with 1,000 concurrent users and a ramp-up of 500. The environment was configured to stress the routing layer and eliminate caching as a variable.

Key Highlights​

• +550 RPS Performance Improvements - Optimizations in request handling and object initialization.
• Priority Quota Reservation - Proxy admins can now reserve TPM/RPM capacity for specific keys.

Priority Quota Reservation​

This release adds support for priority quota reservation. This allows Proxy Admins to reserve specific percentages of model capacity for different use cases.

This is great for use cases where you want to ensure your realtime use cases must always get priority responses and background development jobs can take longer.

This release adds support for priority quota reservation. This allows Proxy Admins to reserve TPM/RPM capacity for keys based on metadata priority levels, ensuring critical production workloads get guaranteed access regardless of development traffic volume.

+550 RPS Performance Improvements​

This release delivers significant RPS improvements through targeted optimizations.

We've achieved a +500 RPS boost by fixing cache type inconsistencies that were causing frequent cache misses, plus an additional +50 RPS by removing unnecessary coroutine checks from the hot path.

Team Member Rate Limits​

LiteLLM MCP Architecture: Use MCP tools with all LiteLLM supported models

This release adds support for setting rate limits on individual members (including machine users) within a team. Teams can now give each agent its own rate limits—so that heavy-traffic agents don’t impact other agents or human users.

Agents can authenticate with LiteLLM using JWT and the same team role as human users, while still enforcing per-agent rate limits.

-p 4000:4000 \
ghcr.io/berriai/litellm:v1.75.5-stable

pip install litellm==1.75.5.post2

Key Highlights​

• Redis - Latency Improvements - Reduces P99 latency by 50% with Redis enabled.
• Responses API Session Management - Support for managing responses API sessions with images.
• Oracle Cloud Infrastructure - New LLM provider for calling models on Oracle Cloud Infrastructure.
• Digital Ocean's Gradient AI - New LLM provider for calling models on Digital Ocean's Gradient AI platform.

Risk of Upgrade​

If you build the proxy from the pip package, you should hold off on upgrading. This version makes prisma migrate deploy our default for managing the DB. This is safer, as it doesn't reset the DB, but it requires a manual prisma generate step.

Users of our Docker image, are not affected by this change.

Redis Latency Improvements​

This release adds in-memory caching for Redis requests, enabling faster response times in high-traffic. Now, LiteLLM instances will check their in-memory cache for a cache hit, before checking Redis. This reduces caching-related latency from 100ms for LLM API calls to sub-1ms, on cache hits.

Responses API Session Management w/ Images​

LiteLLM now supports session management for Responses API requests with images. This is great for use-cases like chatbots, that are using the Responses API to track the state of a conversation. LiteLLM session management works across ALL LLM API's (including Anthropic, Bedrock, OpenAI, etc). LiteLLM session management works by storing the request and response content in an s3 bucket, you can specify.

• Model-level Guardrails - Only run guardrails when specific models are used.
• MCP Header Propagation - Propagate headers from client to backend MCP.
• New LLM Providers - Added Bedrock inpainting support and Recraft API image generation / image edits support.

Auto-Router​

This release introduces auto-routing to models based on request content. This means Proxy Admins can define a set of keywords that always routes to specific models when users opt in to using the auto-router.

This is great for internal use cases where you don't want users to think about which model to use - for example, use Claude models for coding vs GPT models for generating ad copy.

Key Highlights​

• Vector Stores - Support for Vertex RAG Engine, PG Vector, OpenAI & Azure OpenAI Vector Stores.
• Bulk Editing Users - Bulk editing users on the UI.
• Health Check Improvements - Prevent unnecessary pod restarts during high traffic.
• New LLM Providers - Added Moonshot AI and Vercel v0 provider support.

Vector Stores API​

This release introduces support for using VertexAI RAG Engine, PG Vector, Bedrock Knowledge Bases, and OpenAI Vector Stores with LiteLLM.

This is ideal for use cases requiring external knowledge sources with LLMs.

This brings the following benefits for LiteLLM users:

Proxy Admin Benefits:

• Fine-grained access control: determine which Keys and Teams can access specific Vector Stores
• Complete usage tracking and monitoring across all vector store operations

Developer Benefits:

• Simple, unified interface for querying vector stores and using them with LLM API requests
• Consistent API experience across all supported vector store providers

Get started

Bulk Editing Users​

v1.74.7-stable introduces Bulk Editing Users on the UI. This is useful for:

• granting all existing users to a default team (useful for controlling access / tracking spend by team)
• controlling personal model access for existing users

Read more

Health Check Server​

This release brings reliability improvements that prevent unnecessary pod restarts during high traffic. Previously, when the main LiteLLM app was busy serving traffic, health endpoints would timeout even when pods were healthy.

Starting with this release, you can run health endpoints on an isolated process with a dedicated port. This ensures liveness and readiness probes remain responsive even when the main LiteLLM app is under heavy load.

MCP Gateway: Model Access Groups​

v1.74.3-stable adds support for adding MCP servers to access groups, this makes it easier for Proxy Admins to manage access to MCP servers across users and teams.

For developers, this means you can now connect to multiple MCP servers by passing the access group name in the x-mcp-servers header.

Read more here

MCP Gateway: Tool Cost Tracking​

This release adds cost tracking for MCP tool calls. This is great for Proxy Admins giving MCP access to developers as you can now attribute MCP tool call costs to specific LiteLLM keys and teams.

You can set:

• Uniform server cost: Set a uniform cost for all tools from a server
• Individual tool cost: Define individual costs for specific tools (e.g., search_tool costs $10, get_weather costs $5).
• Dynamic costs: For use cases where you want to set costs based on the MCP's response, you can write a custom post mcp call hook to parse responses and set costs dynamically.

Get started

Model Hub v2​

v1.74.3-stable introduces a new OSS Model Hub for telling developers what models are available on the proxy.

This is great for Proxy Admins as you can now tell developers what models are available on the proxy.

This improves on the previous model hub by enabling:

• The ability to show Developers models, even if they don't have a LiteLLM key.
• The ability for Proxy Admins to select specific models to be public on the model hub.
• Improved search and filtering capabilities:
  • search for models by partial name (e.g. xai grok-4)
  • filter by provider and feature (e.g. 'vision' models)
  • sort by cost (e.g. cheapest vision model from OpenAI)
