You can look up a high level instance type type here

That link and the script below only show on-demand availability. Trainium instances in some regions are only available through Capacity Blocks.

The script below will find all the regions you have access to and display which ones have Inferentia2 or Trainium instances types enabled. Watch for announcements from AWS for availability in new regions, check the sample output below, or run the script yourself for a customized list! (some regions require opt-in. If you have not opted into those regions, you will not see them in your results).

This script requires the AWS CLI to be installed and configured.

This only shows whether the instance type is available in that region, it does NOT show that there are available instances for deployment this moment.

Example output is below.
