| Which plan to pick | The free plan is now good enough to use properly, so stay on it until the image, voice or research limits annoy you. Plus is the sensible upgrade. Only look at Pro if you run Codex or deep research all day, and read the current tier details first: Pro 200 now comes with a smaller allowance than it did before 29 September. | Skip the free plan for anything serious now that it's Flash-Lite only. AI Pro (US$19.99, or A$32.99 in Australia) is the one to buy: it's the cheapest way to get Gemini 4 Argon plus Gemini in Docs and Gmail, and the 5 TB of storage offsets a Google One bill. Ultra is for people generating video all day. | Try the free plan to see the agent's output. If you like it, Plus at $19 is the sensible plan, and the yearly price drops it to $15. Only move up if you keep running out of credits, which long Swarm jobs do quickly. |
