W&B Weave

W&B Weave is a framework for tracking, experimenting with, evaluating, deploying, and improving LLM-based applications. Designed for flexibility and scalability, Weave supports every stage of your LLM application development workflow:

  • Tracing & Monitoring: Track LLM calls and application logic to debug and analyze production systems.
  • Systematic Iteration: Refine and iterate on prompts, datasets and models.
  • Experimentation: Experiment with different models and prompts in the LLM Playground.
  • Evaluation: Use custom or pre-built scorers alongside our comparison tools to systematically assess and enhance application performance.
  • Guardrails: Protect your application with safeguards for content moderation, prompt safety, and more.
