W&B Weave

LLM evaluation and observability toolkit from Weights & Biases

AI Infrastructure & MLOpsFreemium

Weave is Weights & Biases' dedicated toolkit for building, evaluating, and iterating on LLM applications. It provides automatic tracing of LLM calls and chain executions, systematic evaluation frameworks for comparing prompts and models, and a dataset management system for curating evaluation examples from production traces. Weave integrates with W&B's existing experiment tracking to provide a complete picture of AI application performance. ML engineers building LLM pipelines, teams running systematic prompt and model evaluations, and organizations implementing evals-driven LLM development use Weave to move beyond ad-hoc testing to principled AI application quality improvement.
