Cursor
Cursor is a vscode clone dedicated to AI coding, nice!!
It is deployed as an all-in-one app bundle, hrmph, configure it in Ubuntu like this.
To select the AI models that will assist you while coding:
   0 run cursor, import vscode settings (but not projects)
   1 run cursor (it's an all-included app file, see ~/app/cursor)
   2 Settings > Models > 
       select your models, there is an insane amount of coverage here!
Specifically for Gemini:
   0 run cursor, import vscode settings (but not projects)
   1 go to google ai studio, get an API key
   2 run cursor (it's an all-included app file, see ~/app/cursor)
   3 Settings > Models > 
       disable all but latest gemini
       add API key to gemini
