LiteLLM AI Gateway

Open Source AI Gateway for 100+ LLMs. Self-hosted. Enterprise-ready. Call any LLM in OpenAI format.

LiteLLM Proxy Server (AI Gateway) | Hosted Proxy | Enterprise Tier | Website

--- ## What is LiteLLM LiteLLM is an open source AI Gateway that gives you a single, unified interface to call 100+ LLM providers — OpenAI, Anthropic, Gemini, Bedrock, Azure, and more — using the OpenAI format. Use it as a **Python SDK** for direct library integration, or deploy the **AI Gateway (Proxy Server)** as a centralized service for your team or organization. [**Jump to LiteLLM Proxy (LLM Gateway) Docs**](https://docs.litellm.ai/docs/simple_proxy)
[**Jump to Supported LLM Providers**](https://docs.litellm.ai/docs/providers) --- ## Why LiteLLM Managing LLM calls across providers gets complicated fast — different SDKs, auth patterns, request formats, and error types for every model. LiteLLM removes that friction: - **Unified API** — one interface for 100+ LLMs, no provider-specific SDK juggling - **Drop-in OpenAI compatibility** — swap providers without rewriting your code - **Production-ready gateway** — virtual keys, spend tracking, guardrails, load balancing, and an admin dashboard out of the box - **8ms P95 latency** at 1k RPS ([benchmarks](https://docs.litellm.ai/docs/benchmarks)) ### OSS Adopters

Both give you a unified interface to access multiple LLMs (100+ LLMs). Choose the option that best fits your needs:

	LiteLLM AI Gateway	LiteLLM Python SDK
Use Case	Central service (LLM Gateway) to access multiple LLMs	Use LiteLLM directly in your Python code
Who Uses It?	Gen AI Enablement / ML Platform Teams	Developers building LLM projects
Key Features	Centralized API gateway with authentication and authorization, multi-tenant cost tracking and spend management per project/user, per-project customization (logging, guardrails, caching), virtual keys for secure access control, admin dashboard UI for monitoring and management	Direct Python library integration in your codebase, Router with retry/fallback logic across multiple deployments (e.g. Azure/OpenAI) - Router, application-level load balancing and cost tracking, exception handling with OpenAI-compatible errors, observability callbacks (Lunary, MLflow, Langfuse, etc.)

**Stable Release:** Use docker images with the `-stable` tag. These have undergone 12 hour load tests, before being published. [More information about the release cycle here](https://docs.litellm.ai/docs/proxy/release_cycle) Support for more providers. Missing a provider or LLM Platform, raise a [feature request](https://github.com/BerriAI/litellm/issues/new?assignees=&labels=enhancement&projects=&template=feature_request.yml&title=%5BFeature%5D%3A+). ### Run in Developer Mode #### Services 1. Setup .env file in root 2. Run dependant services `docker-compose up db prometheus` #### Backend 1. (In root) create virtual environment `python -m venv .venv` 2. Activate virtual environment `source .venv/bin/activate` 3. Install dependencies `uv sync --all-extras --group proxy-dev` 4. `uv run prisma generate` 5. `prisma generate` 6. Start proxy backend `python litellm/proxy/proxy_cli.py` #### Frontend 1. Navigate to `ui/litellm-dashboard` 2. Install dependencies `npm install` 3. Run `npm run dev` to start the dashboard ### Verify Docker Image Signatures All LiteLLM Docker images published to GHCR are signed with [cosign](https://docs.sigstore.dev/cosign/overview/). Every release is signed with the same key introduced in [commit `0112e53`](https://github.com/BerriAI/litellm/commit/0112e53046018d726492c814b3644b7d376029d0). **Verify using the pinned commit hash (recommended):** A commit hash is cryptographically immutable, so this is the strongest way to ensure you are using the original signing key: ```bash cosign verify \ --key https://raw.githubusercontent.com/BerriAI/litellm/0112e53046018d726492c814b3644b7d376029d0/cosign.pub \ ghcr.io/berriai/litellm: ``` **Verify using a release tag (convenience):** Tags are protected in this repository and resolve to the same key. This option is easier to read but relies on tag protection rules: ```bash cosign verify \ --key https://raw.githubusercontent.com/BerriAI/litellm//cosign.pub \ ghcr.io/berriai/litellm: ``` Replace `` with the version you are deploying (e.g. `v1.83.0-stable`). --- # Enterprise For companies that need better security, user management and professional support [Get an Enterprise License](https://litellm.ai/enterprise) [Talk to founders](https://enterprise.litellm.ai/demo) This covers: - ✅ **Features under the [LiteLLM Commercial License](https://docs.litellm.ai/docs/proxy/enterprise):** - ✅ **Feature Prioritization** - ✅ **Custom Integrations** - ✅ **Professional Support - Dedicated discord + slack** - ✅ **Custom SLAs** - ✅ **Secure access with Single Sign-On** # Contributing We welcome contributions to LiteLLM!
