Unable to reach model provider. Max dimensions:2000?

[frank_h (frncis)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

i am only halfway (46%) through my monthly usage on the the $200 ultra plan, and now since last night i am unable to reach any model provider besides new codex 5.1 max. i am getting the error saying max dimensions 2000px but i am not even trying to use a phot or anything. i updated my on demade usage as well and it just wont let me spend or use any models.

Steps to Reproduce

no real steps to reproduce, contact cursor and they said it has nothing to do with max dimensions but is a backend issue with cursors storage system?

Expected Behavior

cannot use any model at all besides new 5.1 codex max

Does this stop you from using Cursor

Yes - Cursor is unusable

Opening a new agent chat window seems to have resolved the issue.

Hey, thanks for the report. Based on the log and screenshot, this might be a chat state glitch or an extensions/MCP conflict.

Please try:

1. Create a new Agent chat and repeat the request
2. Launch a clean profile and test models:
   • In the terminal: cursor --user-data-dir="CursorData/Test"
3. If it works in the clean profile, go back to your main one and:
   • Remove the Nx Console extension (if installed) nrwl.angular-console - this fixed the issue here: Unable to Reach Model Provider for All Models Except Composer1
   • Temporarily rename .cursor/mcp.json in your repo and check if there’s a problematic MCP server (in that thread the cause was the Vercel AI Elements MCP)

If it doesn’t help, please share:

• 2–3 Request IDs from failed attempts
• A screenshot of Settings > Network > Run Diagnostics
• Errors from Help > Toggle Developer Tools > Console
• Which models and modes reproduce the issue

Let me know which of these worked.
