Quick Setup (< 1 hour)

You can use Braintrust to observe AI applications in production by tracing prompts, responses, and tool calls in real-time. Monitor quality with automated evaluations using LLMs, code, or human scoring. Turn production traces into evaluation datasets with one click to catch regressions before deployment. Compare different prompts and models side-by-side, track latency and costs, and get alerts when AI performance degrades. Build custom annotation interfaces for different AI tasks without frontend development.
