What happened
Microsoft unveiled seven new in-house AI models at its Build 2026 conference on June 2. They sit under the MAI, or Microsoft AI, family name. The lineup includes MAI-Thinking-1 for reasoning, MAI-Code-1-Flash for coding, MAI-Image-2.5 for images, MAI-Transcribe-1.5 for transcription, and MAI-Voice-2 for speech.
Microsoft says the models were trained from scratch on clean, commercially licensed data, with no distillation from OpenAI or any other outside model. The models will also be available on Fireworks AI, Baseten, and Open Router. MAI-Code-1 is now in Copilot and VS Code.
Why it matters
Microsoft has leaned on OpenAI models for years. Building its own strong models lowers that reliance and can cut costs. Training on licensed data also reduces legal risk around copyright.
The move makes Microsoft both a partner and a rival to OpenAI, which changes the balance in the AI market.
MintedBrain take
For developers, more model choices inside Copilot and VS Code is good news. The clean data claim is notable, since it may ease copyright worries. Test the MAI coding model against your current tools to see if the cost and quality fit your work.
