| Which plan to pick | 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. | Personal. If you have Claude Pro, run Claude Code inside Zed and you are done. Pro only makes sense if you want Zed's built-in assistant and edit predictions without setting up API keys. |
