| Which plan to pick | 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. | There's nothing to buy. Use it free, and pay for whichever assistant comes out best for your work. | Start free and see how often you hit the Pro search limit. If you research most days, Pro pays for itself in saved tabs. Its 4,000 bonus Computer credits are a one-off and run out after about 30 days, so don't count them as a monthly allowance. Max only makes sense if you're using the Computer agent heavily enough to burn through the credits. |
