For AI issues: which model did you use?

Opus

Does this stop you from using Cursor

Hey, thanks for the report. I’ll need a bit more info to figure it out:

  1. Request ID: Open the chat context menu (three dots in the top right) → Copy Request ID, then paste it here.
  2. Which Opus version is this? Opus 4.5 or something else?
  3. What exactly happens? Do you just get an empty reply, or does the UI show “planning next moves” or “running” and then hang?
  4. Do other models work? Try the same request on Claude Sonnet 4.5 or GPT-5. Do they reply normally?
  5. Network Diagnostics: Go to Cursor Settings CTRL + SHIFT + J → Network → Run Diagnostics, then share a screenshot of the results.

There’s a known issue where the agent replies but the UI doesn’t show the messages. Can you screenshot what you see in the chat when this happens?

Thanks, it seems that Opus 4.5 is responding again, maybe some LLM network provider issue?
Other models did respond normally
