About Weights & Biases

Weights & Biases is a platform for experiment tracking, model management and LLM app development used by ML teams. In everyday use, its Weave toolkit traces and evaluates generative AI applications alongside classic training metrics and artifacts. For teams moving agents from prototype to production, that focus on reliability and visibility matters more than adding another layer of fragile automation.
