Regional Availability

On This Page

Appian AI capabilities are available in select AWS regions. This page provides information about which features are supported in each region and how processing regions enable access to AI models across multiple regions.

What AI features are available in my region?

To get started, use this picker to see which features are available by default in your Appian Cloud region. If you're interested in using a feature that isn't available by default, explore regional availability options for ways to get access.

AI Feature Availability by Region
Select your Appian Cloud region to see which AI features are available.

Regional availability options

Appian AI capabilities offer several options to enable customers all over the world to use AI features:

  • Available by default: The AI models that power Appian features are available in certain regions by default. No additional configuration is required to begin using these features.
  • Available via processing regions: AI models that power Appian features can process data in a region you select using a processing region. A processing region enables cross-region processing when your Appian environment is not located in one of the model's supported source regions. Processing region handling does not store or persist your data and maintains all Private AI security standards. You must choose the model and processing region on the AI Services page of the Admin Console.
  • Available via cross-region configuration: Some AI capabilities—including Document Classification AI Skill, Document Extraction AI Skill, Advanced IDP Tools Skill, and AI Document Center (Advanced Layout)—cannot be used in another region via a processing region. To use these features, contact Appian Support.

Use the interactive tool below to explore which models power each feature, view their processing regions, and understand which regions your data may be processed in:

Key concepts for Appian AI regional availability

Keep these concepts in mind when configuring Appian AI regional availability:

  • Data residency: Your data remains within your designated region unless you explicitly configure cross-region support or processing regions.
  • Multi-region processing: Amazon Bedrock processes inference requests only in the regions listed in the processing region. Multi-region processing does not change your environment's primary region.
  • Regional restrictions: Some AI capabilities are only available in specific regions. If your environment is not in a supported region, you can select a processing region to allow processing in a supported region. Note that a processing region may not be available for some AI models.

Processing regions

A processing region is a configuration that defines which geographic regions can process your AI data when the model is generating a response. A processing region controls where inference requests are handled, but it does not store or persist your data.

For details about processing region concepts, see the AI Services page.

Note:  Disabling a model provider is independent of regional configuration. When a provider is disabled, Appian does not route requests to that provider regardless of processing region settings.

Network configuration

Add AI skill endpoints to your network allowlist

To ensure AI skills are available in your environment, find your environment's region in the AI skill endpoints table and add the corresponding endpoints to your network allow list. Add the endpoints that correspond to your site's region, even if you send AI skill data to a different supported region.

For PCI-compliant sites, use the endpoints that include -strict in the string.

Designer endpoints support proper rendering of the user interface. S3 endpoints enable storage for the model and related data.
