Hey, thanks for the report and the screenshots. I can see the difference between the two states.
This is a known issue. The brain icons in the model selector sometimes don’t render, and the models show up with the -thinking suffix in the name instead. A few users have already reported this:
The team is aware. For now, a workaround is that the thinking variants are usually listed below the non-thinking ones. You can also disable the models you don’t need in Cursor Settings > Models to remove the duplicates.
Also, could you let me know if you have an API key enabled?
Let me know if you have any other questions.
