LiteLLM provides a unified LLM gateway with a single OpenAI-compatible API for over 100 models from various providers. It automates cost tracking, budget enforcement, and model fallback routing for seamless LLM integration.
<problem>Developers and platform teams must integrate with many different large language model providers, each with its own API, pricing, and authentication mechanisms. Managing usage costs, enforcing budgets, and handling provider failures across these disparate services is complex and time‑consuming.</problem> <solution>LiteLLM offers a unified LLM gateway that presents a single OpenAI‑compatible API for over 100 models from providers such as OpenAI, Azure, Anthropic, Gemini, and Bedrock. The platform automatically tracks spend, attributes costs to keys, users, teams, or organizations, and enforces budgets and rate limits. Built‑in fallback routing ensures continuity when a primary model is unavailable. Enterprise customers gain additional security and operational controls, including SSO, OIDC/JWT authentication, team/organization admin roles, Prometheus metrics, audit logs, and PagerDuty alerting. LiteLLM can be deployed as a SaaS service or self‑managed open‑source proxy, allowing organizations to choose the model that fits their compliance and scalability needs.</solution> <features> - OpenAI‑compatible proxy covering 100+ LLMs (OpenAI, Azure, Anthropic, Gemini, Bedrock, etc.) - Automatic spend tracking with per‑key/user/team cost attribution - Budget and rate‑limit enforcement, including tag‑based budgets - Model fallback handling for high availability - Enterprise security: SSO, OIDC/JWT auth, team/org admin delegation - Observability: Prometheus metrics, audit logs, PagerDuty alerts - Deployment flexibility: SaaS or self‑hosted open‑source proxy - Extensive documentation and open‑source community (25K GitHub stars, 425+ contributors) </features> <target_audience>Platform engineering teams and enterprises that need to provide large numbers of developers with consistent, cost‑controlled access to multiple LLM providers.</target_audience> <revenue_model>LiteLLM monetizes through a tiered pricing model that includes a paid Enterprise plan with advanced security, support, and admin features, while also offering an open‑source version that can be self‑hosted.</revenue_model> <traction>As of October 12 2025, LiteLLM’s open‑source repository has over 25 K GitHub stars and 425 + contributors, and the service has processed more than 1 billion requests with 80 % uptime.
