`GPT-4.1` in GitHub Copilot will be deprecated on `2026-06-01`
FIG-0531:1

`GPT-4.1` in GitHub Copilot will be deprecated on `2026-06-01`

A fixed sunset date is now on the calendar across chat, inline edits, agent mode, and completions. If GPT-4.1 was your default in Copilot, swap workflows early because breakage risk starts the moment the model disappears.

[ KEY POINTS ]
  1. GitHub set a `2026-06-01` deprecation date, so this is not a soft warning but a scheduled removal.
  2. The change spans Copilot Chat, inline edits, ask, agent mode, and code completions, which means the impact hits nearly every Copilot surface.
  3. GitHub is already pointing users to a suggested alternative, so prompt behavior and output quality should be rechecked before the cutoff.
  4. Teams with saved Copilot habits around GPT-4.1 should update docs and presets now; waiting until June invites avoidable workflow churn.
