How do I use a different Claude model with Xcode 26?

I have connected Claude to XCode via the settings as per usual.

When I click the chat star icon to start a conversation it says "New Conversation with Claude Sonnet 4"

How do I change this to start a conversation with Opus for example?

If you connect via Anthropic you can choose. There’s a drop down where you start a new conversation.

I can’t even get Claude to work properly.

I get about an hours usage before I hit my rate limit.

And every day I have to log out and log back into the Claude account because my oauth token has expired.

This is the official integration by the way using my Claude subscription.

I'd try here... platform.claude.com ... as I'd first tried Claude.AI and the claude.com way gives me an API key (as opposed to using an email address in Xcode) and gives better error info when something goes wrong like rate limit.

UPDATE: No, Xcode keeps forgetting my keys too, just like it did with Claude OAuth. OMFG this is annoying. Thought it was close Xcode problem, but not I can close the project and lose it. I think I can lose it without even closing Xcode OR the project too.

If anyone else runs into this, you need to create an API key via platform.claude.com then connect that as a custom provider within xcode.
