All the production datasets are using more recent, improved model versions. ![docs image](https://dev-assets.cms.uipath.com/assets/images/ixp/ixp-docs-image-373776-2f917e01.webp) :::note Having an empty page is expected, because it means that no model is going to be deprecated soon. ::: ![docs image](https://dev-assets.cms.uipath.com/assets/images/ixp/ixp-docs-image-373132-f369d6e1.webp) ### Notice on model deprecation and update requirements To ensure optimal functionality and security, older published model versions (which will be at least 12 months old) may be scheduled for deprecation. ### Deprecation announcement To ensure a smooth transition, all deprecated models are flagged well in advance. You can find early deprecation indicators both within this page and in the **Models** page of the relevant dataset. This proactive approach gives you sufficient time to adjust your work without disruption. ### Transition period Following the initial announcement, you have a transition period of no less than three months. After this period ends, deprecated versions will be deemed unsupported. Consequently, unsupported versions will not be accessible via the API. ![docs image](https://dev-assets.cms.uipath.com/assets/images/ixp/ixp-docs-image-373772-352195d3.webp) ### Unpublishing deprecated models You have to unpublish deprecated model versions after publishing a more recent model version within the same dataset. This ensures the smooth continuation of service and API calls during the transition. ### Updating production automations You should immediately update the production automations that utilized the deprecated models, to a more recent model version. These changes prevent any potential interaction with deprecated models.
