Layer 2: Creation & Orchestration as Braintrust

**Braintrust** is an AI evaluation and observability platform designed to help developers build reliable LLM-powered applications. It provides tools for logging, evaluating, and iterating on AI outputs, with a focus on systematic testing and quality assurance for AI agents and LLM pipelines.

Braintrust's platform enables teams to define evaluation criteria, run automated evals at scale, track prompt performance over time, and compare different model configurations. Its logging infrastructure captures detailed traces of LLM interactions, making it possible to debug and improve agent behavior systematically.

In the agentic economy, Braintrust addresses a critical challenge: as AI agents become more autonomous and handle higher-stakes tasks, the ability to systematically evaluate and monitor their performance becomes essential for safe deployment.
