Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, this is a known issue. Right now, the selection in Explore subagent model isn’t actually applied. Subagents fall back to the Composer or parent model, so you’re seeing a different model than the one you set. It’s not just you, we’re tracking it. More details in this thread: Explore subagent model doesn't work

I can’t share an ETA for the fix yet. We’ll post an update as soon as we have one.
