The AI observability platform for building quality AI products.

Braintrust is an AI observability platform designed to help teams measure, evaluate, and improve AI applications. It offers tools for capturing traces, analyzing logs, adding human feedback, and testing changes with experiments. The platform's architecture is built around a dataset, task, and scorer framework, providing a structured approach to AI testing. Braintrust facilitates collaboration between engineers and product managers, allowing them to debug issues together in real-time. It supports high-volume production traffic and complex testing workflows, ensuring reliable performance at scale. Key features include prompt engineering, batch testing, AI-assisted workflows via the Loop agent, live performance monitoring, and scalable log ingestion with Brainstore, its purpose-built database for AI data. Braintrust's value proposition lies in enabling data-driven decisions, preventing quality regressions, and ensuring safe outputs.
