Microsoft is actively developing a new partnership with Anthropic, OpenAI's main competitor. The company has added Anthropic's AI models to its Copilot assistant, which previously ran mostly on OpenAI technology.
This came a couple of weeks after Microsoft signed an agreement to use Anthropic's artificial intelligence in Office 365 applications such as Word, Excel, and Outlook, writes TechCrunch.
Copilot business users will be able to choose between OpenAI models for deep analysis and Anthropic's Claude Opus 4.1 and Claude Sonnet 4 models for tasks such as complex research, developing specialized AI tools, and building enterprise-grade agents.
The Opus 4.1 is designed for complex logic, programming, and detailed architecture planning, while the Sonnet 4 is ideal for everyday development, big data, and text creation tasks. Both models were introduced in May 2025.
