Opik is Comet's open-source AI observability and LLM evaluation platform for agentic applications.
Opik is an open-source AI observability and evaluation platform from Comet ML that traces every step of an LLM or agentic application, from user turns and context retrieval to tool calls. It pairs end-to-end tracing with automated evaluation so teams can debug and improve agents across development, testing, and production.
Teams score traces with more than 30 LLM-as-a-judge metrics, monitor production traffic with real-time alerts, guardrails, and token-cost tracking, and run Test Suites, an Agent Playground, and a prompt optimizer. The core feature set is free and open source on GitHub, with a scalable managed version offered by Comet for enterprise teams.
