Microsoft is transitioning its Copilot AI assistant from models developed by OpenAI and Anthropic to its own in-house MAI models. The shift aims to significantly reduce costs, with tens of thousands of weekly queries already running through the new models. AI chief Mustafa Suleyman has stated the goal is to "ultimately eliminate" the expense of using external models entirely.
The move is part of a broader strategy to make Copilot more affordable for customers, though it may come at the cost of performance. Users could experience differences in response quality or capabilities compared to the previous models. The transition is already underway in products like Excel and Outlook, signaling a long-term shift in Microsoft's AI infrastructure strategy.
