Gideon Mendels

Gideon Mendels is co-founder and CEO of Comet, an MLOps platform for experiment tracking, production monitoring, and LLM evaluation (including Opik). He has spent years arguing that model work needs the same operational discipline as the rest of engineering.

MLOps before the LLM boom

Comet started in the classical MLOps wave - log experiments, compare runs, collaborate - then extended into LLM evaluation as generative workloads arrived. Mendels's about-page portrait anchors the company's public leadership story.

Opik and LLM evaluation

Recent product pushes (Opik) target tracing and evaluating LLM applications. Company about materials and blogs present that as a continuation of Comet's tracking DNA rather than a separate toy.

On treating models like software

He talks about reproducibility, collaboration, and production feedback loops for model builders. That software-engineering framing is how Comet competes in AIR's MLOps category beside Weights & Biases.
