IXP feature availability

Feature availability for Unstructured and complex documents, with the model each feature depends on and how regional model availability affects it.

Overview

Some Unstructured and complex documents features depend on a specific model, instead of the extraction model selected for the project. A feature is not enabled in a region where its required model cannot be supported, so feature availability can differ from one region to another even though IXP deploys to all production regions at the same time.

If a feature described in this guide is missing from your tenant, the model it depends on might not be available in your region yet.

• Data residency - Where your organization data is stored and processed.
• Access and availability - The regions where the Unstructured and complex documents capability is available.

Feature and model requirements
