you can bring your google api key to try it out, and google used to give $300 free when signing up for billing and creating a key.

when i signed up for billing via cloud console and entered my credit card, i got $300 "free credits".

i haven't thrown a difficult problem at gemini 3 pro it yet, but i'm sure i got to see it in some of the A/B tests in aistudio for a while. i could not tell which model was clearly better, one was always more succinct and i liked its "style" but they usually offered about the same solution.
