# Register models

In the [Model Registry](https://docs.datarobot.com/en/docs/classic-ui/mlops/deployment/registry/reg-create.html), models are listed as registered models containing deployment-ready model packages as versions. Each package functions the same way, regardless of the origin of its model. The Model Registry also contains the [Custom Model Workshop](https://docs.datarobot.com/en/docs/classic-ui/mlops/deployment/custom-models/custom-model-workshop/index.html), where you can create, deploy, and register custom models. Custom inference model packages and external model packages are exclusive to MLOps. After you register a model to the Model Registry, you can generate [Compliance Documentation](https://docs.datarobot.com/en/docs/classic-ui/mlops/deployment/registry/reg-compliance.html) to provide evidence that the components of the model work as intended and the model is appropriate for its intended business purpose. You can also [deploy the model to production](https://docs.datarobot.com/en/docs/classic-ui/mlops/deployment/registry/reg-deploy.html) from the Model Registry.

> Contact your DataRobot representative for information on enabling MLOps-exclusive model package options.
