LiteLLM Review 2026 — Unified API for 100+ LLMs
LiteLLM provides a unified OpenAI-compatible API for 100+ LLMs. Open-source proxy with fallbacks, cost tracking, and rate limiting for production AI applications.
LiteLLM lets platform teams and developers access multiple model providers through an OpenAI-compatible API. It provides routing, retries and fallbacks, virtual keys, spend tracking, budgets, rate limits, logging, and guardrails.
The open-source gateway is self-hosted and free. Enterprise adds SSO, SCIM, audit logs, secret management, multi-region control, air-gapped deployment, support, and SLAs; pricing is based on annual gateway capacity and deployment needs.
Features
- OpenAI-compatible API for 140+ providers and 1,800+ models
- Routes requests across providers, regions, deployments, and keys
- Retries failed requests and provides LLM fallbacks
- Tracks spend by key, user, team, organization, tool, or agent
- Sets budgets, rate limits, model access rules, and guardrails
- Provides request logging and integrations with observability tools
- Supports virtual keys, SSO, JWT/OIDC authentication, and audit logs
- MIT-licensed open-source gateway
Use cases
- Centralize access to multiple LLM providers behind one API
- Route requests to lower-cost or higher-capability models
- Track and charge back model usage across teams
- Cap spending and rate limits for production AI applications
- Provide controlled access to agents and MCP servers
- Run an AI gateway in self-hosted or air-gapped environments
Pros
Cons
Latest updates
- LiteLLM v1.106.7 supports custom video providers on /v1/videos (v1.106.7)
/v1/videos serves providers that custom_provider_map registers. The proxy and its Helm charts no longer package the Lens beta.
- LiteLLM v1.108.0 adds Gemini 4 Argon, Microsoft 365 Copilot and OpenAI Live (v1.108.0)
LiteLLM adds Gemini 4 Argon, Microsoft 365 Copilot, OpenAI Live sessions on /v1/live/sessions and Azure PTU capacity that teams share.
- LiteLLM v1.106.6 and v1.105.7 fix the gzip performance regression (v1.106.6 v1.105.7)
The proxy gzips only dashboard analytics responses, so Accept-Encoding: gzip no longer slows down other requests.
- LiteLLM v1.106.5, v1.105.6, v1.104.8 and v1.103.10 trim failure logs for rejected requests (v1.106.5, v1.105.6, v1.104.8 and v1.103.)
Failure logs for rejected requests keep only core request fields, tags and guardrail details.
- LiteLLM v1.106.4, v1.105.5, v1.104.7 and v1.103.9 refresh image base layers (v1.106.4, v1.105.5, v1.104.7 and v1.103.)
Docker images move to newer base images, so image scans stop flagging brotli 1.2.0 and packages the images never install.
