- GitHub says it deprecated listed models across most Copilot experiences, including chat, inline edits, ask and agent modes, and code completions.
- GitHub says Copilot Enterprise administrators may need to enable alternative models through model policies in Copilot settings.
- GitHub asks users to update workflows and integrations so they use supported models.
- GitHub says its REST API can retrieve and update Copilot model policies for enterprises, teams, agent apps, and organisations.
Catch-up written 24 October 2026 for 2026-10-19; covers a source published 2026-10-19.
A retired model can break an integration or change a team workflow even when your application code has not changed.
Choose each model your product and team tools call. Record any published retirement date, its replacement, and the person responsible for switching it.
Put it to work 30 minutes
An owned model-retirement inventory and calendar

Use a real, bounded workflow and record unknowns rather than estimating them. Keep the result small enough to review with a teammate.
- Workflow or decision
- A real workflow the team repeats each week.
- Evidence to record
- Quality, time, cost, failures, and reviewer notes.
- Decision rule
- Keep the current approach unless the agreed checks pass.

Individuals may need no action when Copilot removes deprecated models. Keep the inventory focused on workflows, integrations, and policies your team actually controls.
Reported facts and quotations were checked against the named sources; the recommended exercise is editorial guidance to test in your own context.
Can every model dependency be switched before its next retirement date?
