Visual Studio Code 1.100, the April 2025 release of Microsoft’s IDE, was released one day ago on May 8.
The new version now uses GPT-4.1 as the default base model in AI chat, though it’s a progressive roll-out feature that may not yet be available to all users.
It implemented support for OpenAI’s apply patch editing format (GPT 4.1 and o4-mini) and Anthropic’s replace string tool (Claude Sonnet 3.7 and 3.5), that results significantly faster edits, especially in large files.
