Model Registry
The central model registry that registers, versions, and promotes trained models — and connects them to deployment.
Register your best models in the registry, manage versions, and promote them through stages such as staging and production. Webhooks and Automations integrate with CI/CD to automatically trigger validation and deployment, while tracking each model's lineage.
What Is Model Registry
Among the many models experiments produce, it's critical to manage what goes to production and on what basis. W&B Registry centrally registers and versions the models you promote, connecting staged promotion and automation (webhooks) to your validation and deployment pipelines — a control tower for your models.
