Weave

A Weights and Biases toolkit for tracing and evaluating LLM applications.

Definition

Weave is an open-source toolkit from Weights and Biases aimed at language model application development. It automatically traces LLM calls, retrieval steps, and tool invocations within a pipeline, storing the inputs and outputs of each step. It also provides evaluation primitives for scoring model behavior on datasets, focusing on the application layer rather than raw training metrics.
