Unable to reach model provider. Max dimensions:2000?

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.
