DISCOVERED ON EARLYCOVEWhat is Braintrust?
Braintrust helps teams observe AI applications, run evaluations and catch regressions. Its focus is useful when development examples and real production behavior have drifted apart. Try taking a concrete failure from a trace, turning it into an evaluation and comparing two versions of your application. That complete feedback loop is a better adoption test than simply confirming that events appear in a dashboard.
Made for
