For AI issues: which model did you use?

Sonnet 4.6, but this problem is on all the models

For AI issues: add Request ID with privacy disabled

Request ID: b7beffec-3028-47ef-8c97-d50bf33b5c1d

Additional Information

look at the picture i give, the answer is not complete, but the model stopped

Does this stop you from using Cursor

Yes - Cursor is unusable

We checked the request ID you shared. On our side, the model actually generated a complete response (the full Python overview you asked for). The issue is that the streaming connection to your Cursor client appears to be dropping during delivery, so you’re only seeing a partial response before it cuts off.

This is a connection-layer issue rather than a model problem. A few things to try:

  1. Disable HTTP/2: Open App Settings (Ctrl+,), search for “HTTP/2”, and enable Disable HTTP/2. This often fixes cut-off responses when the connection is unstable.

  2. Run Network Diagnostics: Go to Cursor Settings > Network > Run Diagnostics and copy the results here. This will help us see the connection quality between your machine and our servers.

  3. Check your network setup: If you’re behind a corporate proxy, firewall, or any network restrictions, those can interrupt the streaming connection. Trying a different network is a good test.

If the issue persists after disabling HTTP/2, please share:

  • The Network Diagnostics results

  • A Request ID from a new attempt where the response was still cut off
