Overview

Concrete tool for explicitly enabling LLM provider tracing with optional configuration provided by the Wandb Weave library.

Description

The patch_openai(), patch_anthropic(), and similar patch_*() functions explicitly enable Weave tracing for a specific LLM provider. Each accepts an optional IntegrationSettings parameter to customize tracing behavior. Internally, they delegate to _patch_integration() which imports the provider module and applies the patcher.

Usage

Call patch_openai() (or the equivalent for your provider) after weave.init() when you need explicit control over integration patching or want to customize settings.
