MAI-Code-1-Flash has completed its rollout to 100% of GitHub Copilot Free, Education, Pro, Pro+, and Max subscribers in VS Code. What started as a gradual launch at Microsoft Build 2026 is now live for every individual Copilot user , no configuration required. Copilot CLI support and an Enterprise/Business preview are still on the way.
Microsoft's first model it truly owns
MAI-Code-1-Flash is Microsoft's first coding model built entirely without OpenAI. For years, Microsoft's AI strategy ran through a single supplier , OpenAI powered Copilot, Azure OpenAI Service, and most of Microsoft's product surface. That relationship created dependency, and dependency creates cost exposure. MAI-Code-1-Flash is the first public signal that Microsoft is building serious in-house model capacity that doesn't route through OpenAI.
In April 2026, restrictions in the Microsoft-OpenAI partnership were lifted, giving Microsoft the right to serve its own models in products rather than defaulting to OpenAI. Build 2026 is the first full public exercise of that right. The one-line summary: Microsoft just stopped being only a customer of frontier labs and started being a competitor to them, starting in the place it controls most , the IDE.
