What Opik LLM Eval does
Opik is an open-source platform from Comet for tracing and evaluating LLM and agent applications. Its tracing logs every step an agent takes, including user interactions, context retrieval and tool calls, and lets teams annotate traces and produce audit logs. Evaluation includes LLM-as-a-judge metrics, with 30+ metrics for answer relevance such as context precision, task completion and hallucination. Test suites use plain-text assertions with pass/fail results, and production traces can be evaluated in real time with alerts. Prompt management tracks and versions prompts and parameters, and a prompt optimizer offers six algorithms. Users can download the code from GitHub and run it locally. The page states that no credit card is needed to sign up and that a free tier exists, but it does not list prices or tier limits.
