| Which plan to pick | Start on Pro. It is enough to build a small site or tool in evenings and weekends. If you hit the limit most days, Max 5x is the next step; it costs five times as much but usually works out cheaper than paying for the API directly. Max also lets you spend up to half your weekly limit on Fable, which Pro only gets through paid credits. | Start on the free Individual tier; it is the whole point. If you hit the weekly limits and you also use Gemini for other things, Google AI Pro at $19.99 is a sensible step. Ultra only makes sense for full-time developers. | Pro at $20 is the place to start, and you get $20 off your first paid month when you upgrade. Use the Auto model to make credits last, and only move up a tier once you know your monthly usage. |
