Microsoft favors Anthropic over OpenAI for Visual Studio Code
"Microsoft is adding automatic AI model selection to its Visual Studio Code editor that will automatically pick the best model for "optimal performance." This new auto model feature will select between Claude Sonnet 4, GPT-5, GPT-5 mini and other models for GitHub Copilot free users, but paid users will "primarily rely on Claude Sonnet 4." It's a tacit admission from Microsoft that the software maker is favoring Anthropic's AI models over OpenAI's latest GPT-5 models for coding and development. Sources familiar with Microsoft's developer plans tell me that the company has been instructing its own developers to use Claude Sonnet 4 in recent months."
""We're also going to be making significant investments in our own cluster. So today, MAI-1-preview was only trained on 15,000 H100s, a tiny cluster in the grand scheme of things," said Microsoft AI chief Mustafa Suleyman, in an employee-only town hall last week. Microsoft is also reportedly planning to use Anthropic's AI models for some features in its Microsoft 365 apps soon. The Information reports that the Microsoft 365 Copilot will be "partly powered by Anthropic models," after Microsoft found that some of these models outperformed OpenAI in Excel and PowerPoint."

Internal benchmarks recommend Claude Sonnet 4 for GitHub Copilot. Microsoft plans significant investments in its own AI training clusters; MAI-1-preview was trained on 15,000 H100s. Microsoft will also use Anthropic models in some Microsoft 365 Copilot features after better performance in Excel and PowerPoint. Complex investment and revenue ties with OpenAI remain in place.
