Comet

Comet provides Opik, an end-to-end AI observability platform designed for developers to test, optimize, and monitor their AI agents and LLM applications. It offers comprehensive LLM observability, allowing users to log, annotate, and evaluate every step an agent takes. With features like automated performance scoring using 30+ LLM-as-a-judge metrics, a powerful built-in coding agent (Ollie) for automated code fixes, and robust production monitoring, Comet helps teams ensure consistent performance, track model costs, and accelerate AI development cycles. Opik is truly open source and backed by Comet's enterprise-grade infrastructure, supporting easy integration with frameworks like LlamaIndex, LangChain, OpenAI, PyTorch, and TensorFlow.
