OpenAI 宣布 GPT 5.6 成为微软 Copilot 365“首选模型”，回应分手传言

英文标题：OpenAI says GPT 5.6 is the ‘preferred model’ for Microsoft Copilot 365 amid breakup chatter

OpenAI 在发布 GPT 5.6 时宣布，该模型将成为微软 365 Copilot 的“首选模型”，继续为 Word、Excel 等应用提供支持。此前有报道称微软正用自有模型 MAI 部分替代 OpenAI 软件以节约成本，引发两家公司关系疏远的猜测。此次“首选模型”的披露意在淡化分手传闻，但并未否认微软正更多依赖自身模型的趋势。对开发者而言，这意味着 OpenAI 仍将深度嵌入微软生态，但成本与模型选择上的竞争将继续。

本周早些时候，彭博社报道称，微软正用自家内部模型替换部分 OpenAI 软件以降低成本。报道指出，这些被称为 MAI 的内部模型已被用于驱动 Word 和 Excel 等应用。

这则消息引发了一个关于两家公司日益常见的问题——它们曾看似密不可分，最近却对其“暧昧状态”释放出相互矛盾的信号：两家公司正在渐行渐远吗？

现在，OpenAI 正试图平息这类分手暗示。在周四发布 GPT 5.6 期间，该公司宣布该模型将成为驱动微软 365 Copilot 的“首选模型”。

OpenAI 在相关博客文章中指出，GPT 5.6 将为微软一系列生产力应用中的用户提供支持，包括 Word、Excel、PowerPoint 和 Cowork。

“我们与微软的合作一直致力于将先进 AI 的益处带给更多个人和组织，我们很高兴在这一共同承诺基础上继续前行。”OpenAI 写道。

成为“首选模型”究竟意味着什么，除了表明 OpenAI 的软件将继续驱动微软应用外，并不完全清楚。

话虽如此，此前从未有报道称 ChatGPT 的软件将停止为微软应用提供动力——仅仅是说微软为降低成本正越来越多地使用自家软件。新的“首选模型”披露似乎并未否定此前的这些报道。

English / 原文

Earlier this week, Bloomberg reported that Microsoft was replacing some of OpenAI’s software with its own in-house models to cut costs. Those in-house models, known as MAI, were being used to power apps like Word and Excel, the outlet noted.

The story raised an increasingly common question about the two companies, which were once seemingly inseparable and have recently sent mixed signals about their situationship: Were the two companies drifting apart?

Now, OpenAI is attempting to put any insinuations of such a break to rest. During OpenAI’s launch of GPT 5.6 on Thursday, the company announced that it would become the “preferred model” powering Microsoft’s 365 Copilot.

OpenAI noted in a related blog post that GPT 5.6 would support Microsoft users across the company’s suite of productivity apps, including Word, Excel, PowerPoint, and Cowork.

“Our partnership with Microsoft has always been about bringing the benefits of advanced AI to more individuals and organizations, and we’re excited to continue building on that shared commitment,” OpenAI wrote.

What being a “preferred model” actually means isn’t entirely clear, other than that OpenAI’s software will continue to power Microsoft’s apps.

That said, it was never reported that ChatGPT’s software would stop powering Microsoft’s apps — merely that Microsoft was relying increasingly on its own software in an effort to reduce costs. The new “preferred model” disclosure doesn’t appear to negate that previous reporting.
