Braintrust is a commercial evaluation platform that captures eval runs as immutable, comparable experiment snapshots. The product supports code-based scorers, built-in autoevals, and LLM-as-a-judge evaluators for both offline and production use. Datasets are collections of test cases (input, optional expected output, metadata) sourced from production logs, user feedback, or manual curation. Experiments slot into CI/CD pipelines to detect regressions "before they reach production."
