Hey, thanks for the report.
There’s a related bug we’re already tracking:
- Main thread: The Cursor IDE freezes at the "planning next moves" stage
- Similar cases: Planning next moves stuck, Cursor is unresponsive after sending a prompt to plan
To link your case, please share:
- 2-3 Request IDs captured during the long wait
- A screenshot of Settings - Network - Run Diagnostics
- Indexing & Docs status for your project and for a small empty folder - screenshots
- Whether this helps: Settings - search “HTTP/2” - enable “Disable HTTP/2” - restart
- Behavior on other models (e.g., Composer 1, Haiku 4.5, Opus 4.5) compared to Sonnet 4.5
- Errors from Help - Toggle Developer Tools - Console during the wait
Quick checks:
- In a new chat, run /summarize until context is summarized: Summarization | Cursor Docs
- Try the same request in a small repo or an empty folder - compare time to “Context summarized”
Once you share the details, I’ll add them to the ticket.
