Opik is an open-source AI observability and evaluation platform that helps debug and optimize AI agents by logging steps and automating error detection.

Opik by Comet is an open-source AI observability and evaluation platform designed for AI agents. It logs every step an agent takes, from user interactions to context retrieval and tool calls, and provides automated evaluation workflows to identify and fix errors across development, testing, and production environments. The platform offers end-to-end observability and evaluation tools to help scale agents from prototype to production, ensuring consistent performance through comprehensive logs, repeatable test cycles, and evaluation scores. Key features include tracing and debugging any step in an AI system, evaluating outcomes with LLM-as-a-Judge metrics (using 30+ metrics for relevance, precision, hallucination, etc.), and monitoring agents in production with real-time alerts and guardrails. Opik also provides tools like Test Suites for defining unit tests, Ollie for automatically implementing code fixes with version control, Agent Playground for end-to-end agent testing, and Prompt Optimizer with seven advanced algorithms for maximizing agent performance.
