Rohan Paul@rohanpaul_ai · XBloomberg报道，Microsoft正在Excel和Outlook中用自家模型替代OpenAI和Anthropic的模型，以减少Copilot的推理成本。此前这些应用更依赖外部模型，微软希望减少向控制前沿模型定价的外部实验室支付昂贵调用费用。虽然OpenAI因长期合作仍给予微软优惠，但折扣可能逐渐消退。微软AI负责人Mustafa Suleyman明确表示，目标是减少并最终完全消除外部模型成本。
Bloomberg： Microsoft is replacing OpenAI and Anthropic models inside Excel and Outlook to cut Copilot costs.
Excel and Outlook used to lean more heavily on outside models. Now Microsoft wants fewer expensive calls to labs that control pricing for frontier model access.
OpenAI still gives Microsoft favorable access through their long partnership， but that discount may fade.
Microsoft AI head Mustafa Suleyman has been clear that Microsoft wants to reduce， then remove， that outside cost.
