Stop developing AI
in the dark
Braintrust is the enterprise-grade stack for building AI products. From evaluations, to logging, to prompt playground, to data management, we take uncertainty and tedium out of incorporating AI into your business.
Ship on more than just vibes
Evaluate non-deterministic LLM applications without guesswork and get from prototype to production faster.
Evaluations
We make it extremely easy to score, log, and visualize outputs. Interrogate failures; track performance over time; instantly answer questions like “which examples regressed when I made a change?”, and “what happens if I try this new model?”
DocsLogging
Capture production and staging data with the same code and UI as your evals. Run online evals, capture user feedback, debug issues, and most importantly, find interesting cases to run your evals on.
DocsPrompt playground
Compare multiple prompts, benchmarks, respective input/output pairs between runs. Tinker ephemerally, or turn your draft into an experiment to evaluate over a large dataset.
DocsContinuous integration
Compare new experiments to production before you ship.
Proxy
Access the world's best AI models with a single API, including all of OpenAI's models, Anthropic models, LLaMa 2, Mistral, and others, with caching, API key management, load balancing, and more built in.
DocsDatasets
Easily capture rated examples from staging & production, evaluate them, and incorporate them into “golden” datasets. Datasets reside in your cloud and are automatically versioned, so you can evolve them without risk of breaking evaluations that depend on them.
DocsHuman review
Integrate human feedback from end users, subject matter experts, and product teams in one place.
