Braintrust

Braintrust is an observability and evaluation platform for AI products, helping teams ship AI-powered features more safely and predictably.

AI quality evaluation (evals)

Braintrust lets you run evals—systematic checks of models and agents on real data—so you can measure how quality changes after updates.

• Compare results after changing prompts, models, or application logic
• Detect regressions and confirm improvements with objective signals
• Validate behavior on realistic scenarios before release

Observability and debugging

The platform collects logs, metrics, and test results to help you understand agent behavior, spot failures, and identify unstable edge cases.

• Centralize logs and metrics for AI features
• Investigate failures and inconsistent outputs
• Reduce the risk of unexpected errors reaching users

Built for product and engineering teams

Braintrust supports teams building commercial AI functionality—from startups to large companies—by enabling an iterate–eval–ship workflow.

• Experiment quickly
• Measure quality consistently
• Roll out changes to production with more confidence
