The tech giant, which has invested over $13 billion in OpenAI, announced that users of Copilot's Researcher agent can now choose between Anthropic's Claude models or OpenAI's technology to handle prompts. However, company administrators must approve Anthropic's models before they are enabled, as their use falls under Anthropic's own terms and conditions.
This move represents Microsoft's effort to diversify its generative AI portfolio. Until now, OpenAI has been the primary provider powering Microsoft's AI-driven tools, including Bing, Windows, and Office. OpenAI itself has been rapidly expanding its network, recently striking a $300 billion cloud deal with Oracle and forging a $10 billion agreement with Broadcom. Nvidia also pledged up to $100 billion in a joint initiative to develop new data centers.
Anthropic, founded in 2021 by former OpenAI executives, has grown quickly, reaching a $183 billion valuation. Its Claude Opus 4.1 reasoning model, designed to handle complex tasks, is the first to launch within Copilot's Researcher feature, giving corporate users an alternative to OpenAI's offerings. Anthropic's Claude Sonnet 4 and Opus 4.1 are also available through Copilot Studio, which lets businesses create custom AI agents.
The models run on Amazon and Google Cloud, while Microsoft remains the exclusive cloud provider for OpenAI's APIs used by third-party developers. Microsoft is also internally testing MAI-1-preview, its own large language model, signaling the company's intent to balance external partnerships with in-house innovation. CEO Satya Nadella recently described AI models as becoming "commodities" as capabilities expand.
Copilot remains central to Microsoft's AI strategy, with gradual rollout across enterprises. According to KeyBanc analysts, about 60% of companies are implementing Copilot for only 10% of their workforce, while just 4% have rolled it out to all users. This development underscores a shifting AI landscape where even close partners like Microsoft and OpenAI adapt to competitive pressures. As Anthropic joins the mix, Microsoft positions Copilot as a versatile hub for next-generation enterprise AI solutions.
