Opik

Opik is an end-to-end LLM evaluation platform built by Comet that enables AI developers to systematically test, evaluate, and monitor language model applications throughout their entire lifecycle. The platform provides observability tools designed to calibrate and validate LLM outputs across development, staging, and production environments. Opik addresses a critical challenge in LLM development: ensuring consistent, reliable, and safe model behaviour before and after deployment. It's particularly valuable for teams building production-grade AI applications who need to move beyond manual testing and implement rigorous evaluation frameworks. By offering integrated evaluation, testing, and monitoring capabilities, Opik helps developers reduce hallucinations, improve output quality, and maintain model performance over time as data distributions shift.
