Cursor IDE

Describe the Bug

When hovering Cursor Grok 4.5 High in the model picker, the tooltip title reads “Cursor Grok 4.5 (fast)” even though Fast is turned off.

Details:

  • Model picker selection shows “Cursor Grok 4.5 High”
  • Effort is set to High
  • Fast toggle in the model options menu is OFF
  • Tooltip footer correctly says “Version: high effort”
  • Tooltip title incorrectly appends “(fast)” anyway

This makes it look like Fast is enabled when it is not.

Steps to Reproduce

  1. Open the model picker in Cursor Agent/chat.
  2. Select Cursor Grok 4.5 and set Effort to High.
  3. Open the model options and confirm Fast is toggled OFF.
  4. Hover the Cursor Grok 4.5 High entry so the model description tooltip appears.
  5. Observe the tooltip title shows “Cursor Grok 4.5 (fast)” despite Fast being off (while the footer still says “Version: high effort”).

Expected Behavior

The tooltip title should reflect the actual Fast setting. When Fast is off, it should not include “(fast)”. For example, it should show “Cursor Grok 4.5” (or similar) and only append “(fast)” when the Fast toggle is enabled.

Additional Information

UI-only labeling bug in the model picker tooltip; no Request ID since no chat request is involved.

Also noted: MAX Mode was ON and Auto was OFF when reproducing. The mismatch is specifically between the Fast toggle state and the “(fast)” suffix in the tooltip title.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey there!

This is a display-only bug, and your read is right: the “(fast)” in the tooltip title doesn’t mean Fast is on.

Your Fast toggle is genuinely off. The request runs at High effort, exactly like the row label (“Cursor Grok 4.5 High”) and the tooltip footer (“Version: high effort”) show. That stray “(fast)” in the title is purely cosmetic - it has no effect on how the model runs or how you’re billed.

For now, go by the row label and the “Version:” footer rather than the title suffix. It’s a known issue on our side and I’ve flagged your report to the team.
