Xcode 26.1 ChatGPT very slow

ChatGPT in Xcode 26.1 is super slow for me. What used to complete in a batter f seconds is now taking tens of minutes.

Context: M2 Pro MBP, Xcode 26.1, macOS 26.1. CPU stays under 50% while ChatGPT returns. Using the minimal setting. Tried restarting, have verified I have nothing running Electron, no other apps are running.

ChatGPT returns fast for the displayed content but the preview window where it renders code per line takes a few seconds per line.

Same problem here.

Same here, on a long file it can go for 30-40 mins and then eventually Xcode crashes.
