Rapidly ship AI
without guesswork

Braintrust is the enterprise-grade stack for building AI products. From evaluations, to prompt playground, to data management, we take uncertainty and tedium out of incorporating AI into your business.

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?”

Evaluations

Prompt 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.

Prompt playground

Continuous integration

Leverage Braintrust in your continuous integration workflow so you can track progress on your main branch, and automatically compare new experiments to what’s live before you ship.

Continuous integration

Datasets

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.

Datasets

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.

Proxy

Braintrust fills the missing (and critical!) gap of evaluating non-deterministic AI systems. We've used it to successfully measure and improve our AI-first products.

We're now using Braintrust to monitor prompt quality over time, and to evaluate whether one prompt or model is better than another. It's made it easy to turn iteration and optimization into a science.

Testing in production is painfully familiar to many AI engineers developing with LLMs. Braintrust finally brings end-to-end testing to AI products, helping companies produce meaningful quality metrics.
