GitHub Copilot is updating its model offerings, with the MAI-Code-1-Flash model scheduled for deprecation across all GitHub Copilot experiences on September 10, 2026. This change coincides with the introduction of MAI-Code-1.1-Flash, a new small-tier coding model from Microsoft that is now rolling out in GitHub Copilot.

Key Points

  • MAI-Code-1-Flash will be deprecated across all GitHub Copilot experiences on September 10, 2026.
  • The deprecation is linked to the launch of MAI-Code-1.1-Flash, which is Microsoft's latest small-tier coding model.
  • MAI-Code-1.1-Flash builds on its predecessor by adding native vision support for image understanding.
  • The new model delivers improvements in coding quality, instruction following, tool use, and performance.
  • MAI-Code-1.1-Flash has a 73% lower list price than MAI-Code-1-Flash.
  • For annual GitHub Copilot subscribers, MAI-Code-1.1-Flash is charged at a 0.25x premium request multiplier.

The model is available to Copilot Free and Student users through auto model selection, while Copilot Pro, Pro+, Max, Business, and Enterprise SKUs can manually select it in addition to auto-selection. GitHub encourages users to update their workflows and integrations to use the new model before the deprecation date.
