W&B Models, from Weights & Biases, helps you train, fine-tune, govern, and manage AI models from experimentation to production. You can run more experiments, analyze them interactively, and quickly build higher-quality models. Use the W&B Registry to centralize the tracking of models, datasets, metadata, and their lineage to support governance, and reproducibility. Also, automate workflows for training, evaluation, and deployment to enable rapid iteration.
