About this tag
MAI models are Microsoft's in-house artificial intelligence models designed to handle routine tasks within Microsoft 365 apps like Excel and Outlook, as well as across Copilot, Azure, and enterprise workflows. Recent reports indicate Microsoft is routing tens of thousands of weekly AI prompts from OpenAI and Anthropic systems to its own MAI models to reduce costs and gain more control over AI operations. The MAI model family includes specialized models for reasoning, code, image generation, speech, and transcription, distributed through Microsoft Foundry. This shift does not end Microsoft's partnership with OpenAI but represents a strategic move to treat AI as a margin-controlled platform, allowing Microsoft to choose the most cost-effective model for each workload.
