Ship LLM products that work.
Braintrust is the end-to-end platform for building world-class AI apps.
Evaluate your prompts and models
Non-deterministic models and unpredictable natural language inputs make building robust LLM applications difficult. Adapt your development lifecycle for the AI era with Braintrust's iterative LLM workflows.
Easily answer questions like “which examples regressed when we changed the prompt?” or “what happens if I try this new model?”
Anatomy of an eval
Braintrust evals are composed of three components—a prompt, scorers, and a dataset of examples.
Prompt
Tweak LLM prompts from any AI provider, run them, and track their performance over time. Seamlessly and securely sync your prompts with your code.
Prompts guide
Scorers
Use industry standard autoevals or write your own using code or natural language. Scorers take an input, the LLM output, and an expected value to generate a score.
Scorers guide
Dataset
Capture rated examples from staging and production and incorporate them into “golden” datasets. Datasets are integrated, versioned, scalable, and secure.
Datasets guideFeatures for everyone
Intuitively designed for both technical and non-technical team members, and synced between code and UI.
Traces
Visualize and analyze LLM execution traces in real-time to debug and optimize your AI apps.
Tracing guide
Monitoring
Monitor real-world AI interactions with insights to ensure your models perform optimally in production.
Logging and monitoring
Online evals
Continuously evaluate with automatic, asynchronous server-side scoring as you upload logs.
