About Braintrust

Braintrust is a platform for evaluating and improving AI products with datasets, scorers and production log analysis. In practice, teams replay real traffic in experiments, compare prompts and models, and gate releases on quality metrics. For teams moving agents from prototype to production, that focus on reliability and visibility matters more than adding another layer of fragile automation.
