There are a few ways to switch models in Claude Code within VS Code:

In the chat prompt, use the /model command — type /model in the input box to open the model selector. This is the primary way.

Keyboard shortcut — you can switch models mid-prompt with Alt+P (Option+P on Mac).

In the CLI / terminal — if you're using the integrated terminal, run claude --model claude-opus-4-5-20251101 (or whichever model string you want) to start a session with a specific model.

Via settings — you can set a default model in ~/.claude/settings.json with something like:

{
  "model": "claude-sonnet-4-5-20250929"
}

This persists across sessions for both the extension and the CLI.

The available models are Opus 4.5, Sonnet 4.5, and Haiku 4.5. Worth noting: Haiku 4.5 automatically uses Sonnet in plan mode and Haiku for execution, so there's some smart model routing built in already.
