Microsoft is leaning towards a new partnership with Anthropic, Openai’s chief fly ball. Starting Wednesday, the software giant will incorporate human AI models into its AI assistant Copilot.
The deal marks yet another step into what was slowly unlocked between former exclusive partners, coming just a few weeks after Microsoft has put in place a contract to use humanity’s AI in Office 365 apps such as Word, Excel, and Outlook.
Copilot Business users can choose between Openai’s deep inference model and the Claude Opus 4.1 and Claude Sonnet 4 for humanity. While Opus 4.1 is designed for complex inference, coding, and deep architecture planning, Sonnet 4 is suitable for everyday development tasks, large-scale data processing and content generation.
