Behest vs LiteLLM
They proxy. We operate.
LiteLLM is an open-source LLM proxy that standardizes API calls across providers. Behest is a managed AI backend — it handles auth, memory, PII scrubbing, rate limiting, token budgets, and more.
LiteLLM
LiteLLM is an open-source Python proxy that provides a unified API for calling 100+ LLM providers. You host it, manage it, and build everything else around it.
Strong at: Multi-provider routing, API standardization, model fallback, and budget controls.
