Cursor has grinded to snail speed. A simple prompt takes 30 mins to run

Hey, thanks for the report. The issue with hanging on “Planning next moves” is a known bug we’re actively investigating. Many users have started reporting it in the last few days.

Similar reports: Planning next moves stuck

In the meantime, try this:

  • Start a completely new chat (not just clearing the current one - a new one)
  • Fully restart Cursor IDE (not just closing the tab)
  • If you’re using Agent mode, try switching to Ask mode or vice versa
  • Also try closing the project, opening an empty window, and sending a request. Does the speed return? If yes, reopen your project and check again

If the issue persists, let me know.
