Skills
Experiment Based Evals
Runs eval suites over datasets with code and LLM-judge scorers, comparing scores across experiments and model versions.
Production Trace Logging
Captures traces and logs from production AI applications, then queries them to identify recurring failure patterns.
Prompt Playground
Iterates on prompts and models side by side, running them against dataset rows before the change ships to production.
Human Review And Datasets
Collects human feedback on logged spans and promotes interesting production examples into evaluation datasets.
Braintrust CLI
Runs evals, instruments code, queries logs, syncs data, and manages functions from the bt command line.
