Weights & Biases

The MLOps platform used by most top AI research labs for experiment tracking, model management, and collaboration. Weights & Biases (W&B) helps ML teams log experiments, visualize results, and reproduce findings — making the messy process of training models organized and shareable.

• Experiment tracking — log hyperparameters, metrics, and outputs for every training run • Interactive dashboards — visualize and compare experiments with customizable charts • Artifacts — version datasets, models, and pipeline outputs with full lineage tracking • Sweeps — automated hyperparameter optimization with smart search strategies • Reports — create shareable documents combining code, visualizations, and narrative • Team collaboration — share results and reproduce experiments across your organization

Free for personal use. Team plans start at $50/user/mo.
