Commercial transition
Previous stateOrganisations relied on explicit per-model configuration without the new dynamic inherited-default state.
→New stateUnconfigured models inherit GitHub's default enablement state. Explicit enabled or disabled settings remain preserved; open-weight models and models outside GitHub's data-retention agreement are excluded.
Who is affected
GitHub Copilot Business and Enterprise organisations managing model policies.
Action required
Administrators who require manual approval for every model must disable the default before 26 August 2026 and preserve explicit settings.
Evidence boundary
The policy does not guarantee that every model is available to every plan or client and excludes the named model categories.
Timeline
