# W&B Models

W\&B Models is the system of record for ML Practitioners who want to organize their models, boost productivity and collaboration, and deliver production ML at scale.

With W\&B Models, you can:

* Track and visualize all [ML experiments](/models/track/).
* Optimize and fine-tune models at scale with [hyperparameter sweeps](/models/sweeps/).
* [Maintain a centralized hub of all models](/models/registry/), with a seamless handoff point to devops and deployment
* Configure custom automations that trigger key workflows for [model CI/CD](/models/automations/).

Machine learning practitioners rely on W\&B Models as their ML system of record to track and visualize experiments, manage model versions and lineage, and optimize hyperparameters.
