Opik

Opik is the open-source platform for LLM and RAG application evaluation, delivering transparent performance metrics and cutting development cycles.

This is Opik: the open-source LLM observability platform developed by Comet. It provides a structured methodology for evaluating, testing, and monitoring your Large Language Model applications (LLMs) and Retrieval-Augmented Generation (RAG) systems. The core function is clear: log traces, run automated experiments, and visualize key performance metrics like hallucination detection and context relevance. For instance, you can use Opik to track token usage, analyzing spending patterns in USD, or compare multiple prompt versions side-by-side to minimize regressions. It’s designed for scalability (supporting up to 100,000 traces per month on professional plans) and fast iteration, ensuring teams confidently move from development to production.
