Weave is a toolkit for developing AI-powered applications, built by Weights & Biases.

You can use Weave to:

• Log and debug language model inputs, outputs, and traces
• Build rigorous, apples-to-apples evaluations for language model use cases
• Organize all the information generated across the LLM workflow, from experimentation to evaluations to production

Read the docs to get started debugging, evaluating, and monitoring AI applications.

Interested in pulling back the hood or contributing? Awesome, before you dive in, here's what you need to know.

We're in the process of 🧹 cleaning up 🧹. This codebase contains a large amount code for the "Weave engine" and "Weave boards", which we've put on pause as we focus on Tracing and Evaluations.

The Weave Tracing code is mostly in: weave/trace and weave/trace_server.

The Weave Evaluations code is mostly in weave/flow.
