I pay nothing and just rotate between gmail accounts when one hits a usage limit.  I have about a dozen accounts so between all of them i get about as many tokens as i would a single paid account. 

 I started doing it first with Cursor AI, and i still use that too, but now googles Anti-gravity gives access to Claude and the usage limits are separate from the limits for Gemini. With all of it combined I have more then enough usage to do whatever i want without paying any of the corps a dime.
