Microsoft Replaces OpenAI and Anthropic Models with Own AI in Excel and Outlook
A Bloomberg-cited claim about Microsoft's in-house MAI-1 push landed alongside immediate questions on X about whether cheaper will also mean worse.
“Bloomberg: Microsoft is replacing OpenAI and Anthropic models inside Excel and Outlook to cut Copilot costs.”
Rohan Paul@rohanpaul_aiTECH#1260A post on X from Rohan Paul, citing Bloomberg, says Microsoft is replacing OpenAI and Anthropic models inside Excel and Outlook with its own MAI-1 model to cut Copilot costs. The post frames the move as part of a broader push by Microsoft AI chief Mustafa Suleyman to reduce expensive outside model calls, even with Microsoft's long OpenAI partnership still in place. So far, the public sourcing here is that Bloomberg-cited post and the reactions around it on X.
“MAI-1 has no independent benchmarks yet, but the ones they released suggest it is worse than Sonnet 4.6.”
