LiteLLM
Open-source LLM proxy and SDK that routes agent calls to 100+ LLM providers through a single OpenAI-compatible API. Handles cost tracking, load balancing, rate limiting, guardrails, and spend controls across Anthropic, OpenAI, Bedrock, Azure, and more. Self-hostable for free; enterprise tier adds SSO, audit logs, and Prometheus metrics. Critical infrastructure for multi-provider agent cost management.
Solid choice for most workflows
You're building multi-provider agents but drowning in API keys, cost tracking spreadsheets, and provider-specific SDKs that force different error handling and request formats across your codebase.
Immediate wins: one auth layer, consistent error responses, per-request cost/token logging with tags for slicing by team or model. Quirks: you own the proxy infrastructure (unless managed tier); local model support requires community adapters; streaming and non-streaming both work but you must test latency from your edge. Cost tracking is real-time but requires you to wire up callbacks to actually see the data.
Your agent needs to gracefully handle provider outages and cost overruns without manual intervention or code rewrites.
Failover is transparent to your agent code—no retry logic needed. Spend caps are enforced at request time, so you'll see rejections if a team hits budget. Setup is straightforward but requires upfront planning of your fallback strategy and cost allocation model.
You're running agents for multiple teams or customers and need to isolate API keys, budgets, logging, and audit trails without building custom middleware.
Multi-tenant isolation works well for SaaS agents. Logging is consistent across tenants. Key rotation is manual but straightforward. Audit trails are available in enterprise but require you to export and analyze them.
Self-hosted proxy adds operational overhead
Running LiteLLM as your own infrastructure means you own deployment, scaling, monitoring, and uptime. Latency from your agents to the proxy is a new bottleneck. The managed tier removes this but costs extra and locks you into LiteLLM's infrastructure.
Cost tracking requires active callback wiring
LiteLLM logs cost and token counts, but you must configure callbacks (Langfuse, custom webhooks, or GCS/Azure exports) to actually see and act on the data. Without callbacks, you have logs but no visibility. Set up callbacks before opening traffic to production.

What It Actually Does
LiteLLM lets you call AI models from over 100 providers like OpenAI and Anthropic using one simple interface, so you don't rewrite code for each. It tracks costs, balances loads, and limits spending, with a self-hosted server option for teams.[1][3]
