Tracing

W&B Weave provides powerful tracing capabilities to track and version objects and function calls in your applications. This comprehensive system enables better monitoring, debugging, and iterative development of AI-powered applications, allowing you to "track insights between commits."

Key Tracing Features​

Weave's tracing functionality comprises three main components:

Calls​

Calls trace function calls, inputs, and outputs, enabling you to:

  • Analyze data flow through your application
  • Debug complex interactions between components
  • Optimize application performance based on call patterns

Ops​

Ops are automatically versioned and tracked functions (which produce Calls) that allow you to:

  • Monitor function performance and behavior
  • Maintain a record of function modifications
  • Ensure experiment reproducibility

Objects​

Objects form Weave's extensible serialization layer, automatically versioning runtime objects (often the inputs and outputs of Calls). This feature allows you to:

  • Track changes in data structures over time
  • Maintain a clear history of object modifications
  • Easily revert to previous versions when needed

By leveraging these tracing capabilities, you can gain deeper insights into your application's behavior, streamline your development process, and build more robust AI-powered systems.
