GitHub changes new Copilot models to inherit a global default
GitHub introduced a global default policy for generally available Copilot models on Business and Enterprise plans. Unconfigured models were scheduled to inherit the default from 26 August, while explicit choices remained fixed and open-weight or non-data-retention-agreement models stayed excluded.
Why it matters: A dynamic default can widen model access when new models ship without a separate administrator decision. That turns provider lifecycle, data terms and model inventory into an active configuration boundary rather than a one-time procurement choice.
