How Amo and Pimi look
Hold on, I want to warn readers about a pitfall – Ultra 5x/20x was split from the original single US$250 tier into US$99.99/US$199.99, but the official side never explained how existing US$250 users are supposed to migrate; and one.google.com also has a same-named AI Plus US$9.99/2TB plan that coexists – pick the wrong entry point and you'll end up paying more.
I'll admit this pitfall needs pointing out. That said, Pro at US$19.99 includes an expanded quota, which is fairly reasonable for moderate users — Chinese support is full, and it can be paid by credit card along with your Google plan.
So, do you need to pay or not?
To try character consistency and retouching, start with the Gemini free version. For serious image generation, AI Plus at US$4.99 is the most affordable option. However, avoid subscribing through the US$9.99 entry point on one.google.com, as it's more expensive. Only heavy users need Ultra.
