OpenAI vs. Microsoft: The Partnership Tension You Should Be Watching
Bloomberg reported that Microsoft is quietly replacing some OpenAI models in its products with its own in-house AI called MAI — a cost-cutting move that signals real tension between the two companies. OpenAI pushed back, asserting that GPT 5.6 is still the preferred model powering Microsoft Copilot. For SMB owners who rely on Microsoft 365 Copilot, this is a situation worth monitoring: if Microsoft shifts to cheaper in-house models, it could mean changes in Copilot's capability or pricing down the road.
