-Introduced the `AiResource` catalog entity kind as an opt-in backend module. Install this module to register support for `AiResource` entities in your catalog, used to represent contextual information consumed by AI coding tools such as skills and rules.
+Introduced the `AiResource` catalog entity kind. Entity types, validators, type guards, and the model layer are exported from `@backstage/catalog-model/alpha`. Install `@backstage/plugin-catalog-backend-module-ai-model` in your backend to register the kind with the catalog.
