Version prompts, route LLM calls, trace and evaluate — one platform.
Versioned, templated message sets. Move a production alias between versions without redeploying your app.
One OpenAI-compatible endpoint in front of every provider. Bring your own keys; get routing, cost, and caching.
Every call recorded as a trace with spans — model, tokens, latency, cost. Report your own spans too.
Callable functions, versioned like prompts, that you attach to a prompt and hand to the model.
Build datasets from real feedback and run experiments to compare prompt or model versions on quality.
