The use case: how Vercel deploys Braintrust
Vercel uses Braintrust as its eval and observability infrastructure to benchmark newly released AI models against existing ones, catch regressions early, and deploy support for new models quickly. The team also uses production traces to spot quality issues customers may not report directly.
