RAG API​

Introducing a new RAG API on LiteLLM AI Gateway. You can provide documents (TXT, PDF, DOCX files) to LiteLLM's all-in-one document ingestion pipeline and it will handle OCR recognition, chunking, embedding, and storing data in your vector store of choice (OpenAI, Bedrock, Vertex AI, etc.).

Example usage for ingestion

curl -X POST "http://localhost:4000/v1/rag/ingest" \
    -H "Authorization: Bearer sk-1234" \
    -H "Content-Type: application/json" \
    -d "{
        \"file\": {
            \"filename\": \"document.txt\",
            \"content\": \"$(base64 -i document.txt)\",
            \"content_type\": \"text/plain\"
        },
        \"ingest_options\": {
            \"vector_store\": {
                \"custom_llm_provider\": \"bedrock\"
            }
        }
    }"

Example usage for querying the vector store

curl -X POST "http://localhost:4000/v1/vector_stores/vs_692658d337c4819183f2ad8488d12fc9/search" \
    -H "Authorization: Bearer sk-1234" \
    -H "Content-Type: application/json" \
    -d '{
        "query": "What is LiteLLM?",
        "custom_llm_provider": "bedrock"
    }'

Prompt Management​

This release introduces LiteLLM Prompt Studio - a comprehensive prompt management solution built directly into the LiteLLM UI. Create, test, and version your prompts without leaving your browser.

You can now do the following on LiteLLM Prompt Studio:

• Create & Test Prompts: Build prompts with developer messages (system instructions) and test them in real-time with an interactive chat interface
• Dynamic Variables: Use {{variable_name}} syntax to create reusable prompt templates with automatic variable detection
• Version Control: Automatic versioning for every prompt update with complete version history tracking and rollback capabilities
• Prompt Studio: Edit prompts in a dedicated studio environment with live testing and preview

API Integration:

Use your prompts in any application with simple API calls:

response = client.chat.completions.create(
    model="gpt-4",
    extra_body={
        "prompt_id": "your-prompt-id",
        "prompt_version": 2,  # Optional: specify version
        "prompt_variables": {"name": "value"}  # Optional: pass variables
    }
)

Performance – /realtime 182× Lower p99 Latency​

This update reduces /realtime latency by removing redundant encodings on the hot path, reusing shared SSL contexts, and caching formatting strings that were being regenerated twice per request despite rarely changing.

Results​

Test Setup​

Model Compare UI​

New interactive playground UI enables side-by-side comparison of multiple LLM models, making it easy to evaluate and compare model responses.

Features:

• Compare responses from multiple models in real-time
• Side-by-side view with synchronized scrolling
• Support for all LiteLLM-supported models
• Cost tracking per model
• Response time comparison
• Pre-configured prompts for quick and easy testing

Details:

• Parameterization: Configure API keys, endpoints, models, and model parameters, as well as interaction types (chat completions, embeddings, etc.)

• Model Comparison: Compare up to 3 different models simultaneously with side-by-side response views

• Comparison Metrics: View detailed comparison information including:

  • Time To First Token
  • Input / Output / Reasoning Tokens
  • Total Latency
  • Cost (if enabled in config)

• Safety Filters: Configure and test guardrails (safety filters) directly in the playground interface

Agent Hub​

This release adds support for registering and making agents public for your organization. This is great for Proxy Admins who want a central place to make agents built in their organization, discoverable to their users.

Here's the flow:

1. Add agent to litellm.
2. Make it public.
3. Allow anyone to discover it on the public AI Hub page.

Get Started with Agent Hub

Performance – /embeddings 13× Lower p95 Latency​

This update significantly improves /embeddings latency by routing it through the same optimized pipeline as /chat/completions, benefiting from all previously applied networking optimizations.

Built-in Guardrails on AI Gateway​

This release introduces built-in guardrails for LiteLLM AI Gateway, allowing you to enforce protections without depending on an external guardrail API.

• Blocking Keywords - Block known sensitive keywords like "litellm", "python", etc.
• Pattern Detection - Block known sensitive patterns like emails, Social Security Numbers, API keys, etc.
• Custom Regex Patterns - Define custom regex patterns for your specific use case.

Get started with the built-in guardrails on AI Gateway here.

Performance – /responses 19× Lower Median Latency​

This update significantly improves /responses latency by integrating our internal network management for connection handling, eliminating per-request setup overhead.

MCP Gateway - Control Tool Access by Team, Key​

Proxy admins can now control MCP tool access by team or key. This makes it easy to grant different teams selective access to tools from the same MCP server.

For example, you can now give your Engineering team access to list_repositories, create_issue, and search_code tools, while Sales only gets search_code and close_issue tools.

This makes it easier for Proxy Admins to govern MCP Tool Access.

Get Started

Performance - 70% Lower p99 Latency​

This release cuts p99 latency by 70% on LiteLLM AI Gateway, making it even better for low-latency use cases.

These gains come from two key enhancements:

Reliable Sessions

Added support for shared sessions with aiohttp. The shared_session parameter is now consistently used across all calls, enabling connection pooling.

Faster Routing

A new model_name_to_deployment_indices hash map replaces O(n) list scans in _get_all_deployments() with O(1) hash lookups, boosting routing performance and scalability.

As a result, performance improved across all latency percentiles:

• Median latency: 110 ms → 100 ms (−9.1%)
• p95 latency: 440 ms → 150 ms (−65.9%)
• p99 latency: 810 ms → 240 ms (−70.4%)
• Average latency: 310 ms → 111.73 ms (−64.0%)

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%)

MCP OAuth 2.0 Support​

This release adds support for OAuth 2.0 Client Credentials for MCP servers. This is great for Internal Dev Tools use-cases, as it enables your users to call MCP servers, with their own credentials. E.g. Allowing your developers to call the Github MCP, with their own credentials.

Set it up today on Claude Code

Scheduled Key Rotations​

This release brings support for scheduling virtual key rotations on 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.

This is great for Proxy Admins who need to enforce security policies for production workloads.

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.
