Pi Labs

Pi Labs is an AI-powered platform that automatically builds evaluation systems (evals) for AI applications, with a special focus on Large Language Models (LLMs) and agents. Instead of struggling with manual, inconsistent testing, teams can rely on Pi Labs to generate reliable evals that keep pace with their applications.

With Pi Labs, users can create custom scoring models that precisely match real user feedback and prompts, ensuring evaluations are highly accurate and consistent over time. This means fewer false signals and more confidence in every model or agent release.

The platform also integrates seamlessly with a wide range of existing tools, so evaluation fits naturally into your current workflow. At its core is Pi Scorer, a fast and highly accurate foundation model that delivers comprehensive metrics, observability, and agent control across the entire AI stack.
