彭博社报道，微软已在Excel和Outlook中用自研MAI-1替换OpenAI与Anthropic模型，以减少Copilot调用外部模型的高昂费用。微软AI负责人Mustafa Suleyman明确表示要降低并最终消除外部成本。但MAI-1尚无独立基准，已发布结果劣于Claude Sonnet 4.6。学者Ethan Mollick质疑其在Office场景的表现，认为已有更优的Claude/OpenAI插件。微软目前仍通过长期合作获得OpenAI优惠，但折扣可能消退。
MAI-1 has no independent benchmarks yet， but the ones they released suggest it is worse than Sonnet 4.6.
Not sure it is going to be great as a Copilot at Excel and Outlook， especially as there are already quite good Claude/OpenAI plugins for office using good AI. We will see.
