GitHub deprecated several Copilot models across Chat, inline edits, ask and agent modes, and code completions effective September 1, 2026; the changelog excerpt is truncated, so the full list of deprecated models and any replacement recommendations are not visible.

Official deprecation notice from GitHub. Users on specific models should verify which ones are affected and plan migration before the cutover date.
