Using Claude Sonnet 4 in VS Code

Question

I'm using VS Code Copilot AI chat with my Anthropic API Keys. I should be now able to choose Claude Sonnet 4 as an available model but it doesn't show up as an available model.

I did try to add it by:

• Clicking on "Manage models.." in the AI Chat model option select.
• Clicking on "Anthropic"
• A list of checkable model versions shows up but it only contains: Claude 35 Haiku, Claude 3.5 Sonnet and Claude 3.7 Sonnet. I expected to be able to choose the 4 versions but I'm not able to.

I also tried to create a new Api key in the Anthropic console and add it VS code but I still get the same result.

Should I do something else to enable Claude Sonnet 4 in VS Code?

Answer 1

For now you should either use Github Copilot account, or wait for an update in Copilot to support Claude 4 standalone API keys.
