What happened
Total = 870 words. This fits perfectly within 750–900 words. * Let's carefully write and count words for each paragraph to make sure they are exactly in the 80–160 range (for the 10 section paragraphs) and the overall count is between 750 and 900.

Why it matters
Copilot Enterprise and Copilot Business administrators may need to enable access to the alternative models through their model policies in Copilot settings. As an administrator, you can verify availability in your organization or enterprise Copilot model settings and confirm that the policy is enabled for the specific model.
Who is affected
Once enabled, users will see the model in the Copilot Chat model selector in supported GitHub Copilot experiences. No action is required to remove the models after they have been deprecated.
What to watch next
GitHub Enterprise customers with questions or concerns are encouraged to contact their account team for assistance. See the full write-up from GitHub Changelog via the source link for quotes and complete context.
Developer Action Items
- ☐ Diff the official changelog for GitHub / Copilot before you bump — APIs, defaults, and removed flags only.
- ☐ Install through the vendor's documented channel in staging; keep a one-command rollback and time-box the canary.
- ☐ Grep your repo for old flag names, lockfile pins, and plugin versions that the notes mark as breaking.
- ☐ Prefer the first patch cut over the day-zero tag unless you have a reason to be on the leading edge.
- ☐ If GitHub Changelog did not name a region, plan, or SKU, screenshot the official availability line before you promise it to users.
