Tracking training and application behavior
Weights & Biases records and compares machine-learning runs, including hyperparameters, metrics and artifacts. Its Weave tools address another stage: tracing LLM applications, managing prompts and evaluating outputs. These records help developers compare changes and investigate failures without making every observed result a proven improvement in model capability. [2]
A completed acquisition
CoreWeave completed its acquisition on May 5, 2025, following an agreement announced in March. The buyer committed to interoperability across infrastructure providers, models and frameworks. That was a stated platform policy, separate from a guarantee of future product behavior. [1]
