Microsoft is instructing its sales team to directly attack AI models from OpenAI, Google, and Anthropic, promoting the efficiency and cost-effectiveness of its own in-house alternatives.
The shift reflects a broader strategy to replace third-party models in flagship products like Word and Excel with Microsoft's own systems, potentially addressing investor skepticism about the company's heavy AI spending.
What happened
At an internal strategy meeting on Tuesday, Microsoft executives instructed salespeople to negatively compare AI products from OpenAI, Google, and Anthropic against Microsoft's own models. Executive Vice President Jacob Andreou presented a comparison of Copilot to Anthropic's Claude, claiming Claude was "slower and less accurate, and lacked the proper security integrations" in Microsoft's office apps.
Why it matters
Microsoft is shifting away from the AI vendors it long depended on—the company has recently swapped OpenAI and Anthropic models out of flagship apps like Word and Excel in favor of its own, a cost-cutting move. The pivot may help address investor concerns about Microsoft's massive spending on AI infrastructure, since demonstrating competitive in-house models could build confidence in the company's long-term AI strategy.
What to watch
Microsoft and OpenAI amended their partnership in April, dropping the exclusivity clause that once bound them tightly together and clearing OpenAI to sell to Microsoft's competitors—a change that appears to have triggered this more aggressive sales positioning.

Microsoft's pivot toward promoting its own AI models over those of OpenAI and Anthropic marks a significant departure from a long-standing relationship. For years, the two companies maintained an exceptionally close partnership in which Microsoft provided capital and compute resources to OpenAI in exchange for exclusive access to OpenAI's API and models. That exclusivity agreement, however, ended in April when the companies amended their terms, clearing OpenAI to compete and sell directly to Microsoft's rivals. The removal of that protection appears to have prompted Microsoft to accelerate its internal model development and, now, to actively position those models as superior alternatives to its former partners.
The timing also reflects broader pressure on Microsoft's business outlook. The company has faced investor skepticism over the past year regarding its substantial investment in AI infrastructure buildout. By coaching sales teams to highlight the efficiency and cost-effectiveness of its own end-to-end systems—and by swapping third-party models out of flagship applications like Word and Excel—Microsoft appears to be attempting to demonstrate concrete returns on those AI investments and rebuild investor confidence in its long-term strategy.
