| Which plan to pick | The app is free, so the only decision is whether the privacy trade-off is acceptable for what you're asking. If you need the model inside your own software, have a developer use the API or run the open model through a provider that keeps your data in Australia. | 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. |
