Gideon Mendels (Github: @gidim) is the co-founder and CEO of Comet, the end-to-end model evaluation platform for AI developers. Among the tools in the Comet ecosystem is Opik, an open-source solution for evaluating, testing and monitoring LLM applications. Opik allows users to log traces and spans, define and compute evaluation metrics, score LLM outputs, compare performance across app versions, and more. As a true open-source project, its full featureset is available for use by anyone, completely free.
