Language Understanding Intelligent Service (LUIS) will be fully retired on March 31, 2026. LUIS resource creation isn't available. Beginning on October 31, 2025, the LUIS portal will no longer be available. We recommend migrating your LUIS applications to conversational language understanding to benefit from continued product support and multilingual capabilities.
LUIS authoring regions are supported by the LUIS portal. To publish a LUIS app to more than one region, you need at least one prediction key per region.
LUIS Authoring regions
Authoring regions are the regions where the application gets created and the training take place.
LUIS has the following authoring regions available with paired fail-over regions:
- Australia east
- West Europe
- West US
- Switzerland north
LUIS has one portal you can use regardless of region, www.luis.ai.
Publishing regions and Azure resources
Publishing regions are the regions where the application will be used in runtime. To use the application in a publishing region, you must create a resource in this region and assign your application to it. For example, if you create an app with the westus authoring region and publish it to the eastus and brazilsouth regions, the app will run in those two regions.
Public apps
A public app is published in all regions so that a user with a supported prediction resource can access the app in all regions.
Publishing regions are tied to authoring regions
When you first create our LUIS application, you're required to choose an authoring region. To use the application in runtime, you're required to create a resource in a publishing region.
Every authoring region has corresponding prediction regions that you can publish your application to, which are listed in the tables below. If your app is currently in the wrong authoring region, export the app, and import it into the correct authoring region to match the required publishing region.
Single data residency
Single data residency means that the data doesn't leave the boundaries of the region.
Note
- Make sure to set
log=falsefor V3 APIs to disable active learning. By default this value isfalse, to ensure that data does not leave the boundaries of the runtime region. - If
log=true, data is returned to the authoring region for active learning.

Failover regions
Each region has a secondary region to fail over to. Failover will only happen in the same geographical region.
Authoring regions have paired fail-over regions.
The following publishing regions do not have a failover region:
- Brazil South
- Southeast Asia
