Microsoft favors Anthropic over OpenAI for Visual Studio Code

Microsoft is integrating an automatic AI model selection feature into its Visual Studio Code editor. This feature will automatically choose the best model, including Claude Sonnet 4, GPT-5, and GPT-5 mini, to provide optimal performance for GitHub Copilot free users. However, paid users will primarily rely on Anthropic's Claude Sonnet 4 model. This move suggests that Microsoft is favoring Anthropic's AI models over OpenAI's latest GPT-5 models for coding and development tasks. According to sources, the company has been instructing its own developers to use the Claude Sonnet 4 model in recent months. The article highlights Microsoft's strategic decision to prioritize Anthropic's AI technology over OpenAI's offerings within its Visual Studio Code ecosystem, potentially signaling a shift in the company's AI development and integration priorities.
