GitHub Models is retired — playground, catalog, inference API and bring-your-own-key all switched off

GitHub's changelog entry of 30 July 2026 records that GitHub Models is retired in full: the playground, the model catalog, the inference API and bring-your-own-key are, in its words, no longer available to any customer, including existing customers with active usage. GitHub points developers at Microsoft Foundry for a broad model catalog and at GitHub Copilot for model access inside GitHub workflows.

What it means A unified model endpoint that anything in a build could be pointing at is gone with no grace period for existing users; the migration is to Microsoft Foundry or Copilot, and it is not optional.
