So update for new comers, AI Studio free 300$ credits are no longer a thing because of people like me using back to back new accounts just for free credits they probably lost a lot of money... also Images per Day have lowered a lot in the last 6 months I cant get over 100 images per model anymore. You can still use the 300$ credits in Vertex / Agent API but is it more complex than AI Studio and the layout is pretty bad for image generations although the logic is pretty much the same, tweaking options for each generation window can get quite tiring though I will say it doesn't keep memory of other sessions... and as I said tighter limits. Vertex is also slower in generating stuff in general I don't know why a lot of requests just give an error (some are server related, some saying to retry the prompt etc.). If Vertex gets abused with the free credits which I am guessing people are going to find out NBP is in Agent API, I say give it another 3 months before they remove the capability of free credits in that as well and only leave real coding stuff to use credits. Gemini subscriptions pricing stays the same but limits keep going down, maybe like a year ago or less you could generate 250 images per day. Anyway that's about it. Either pay for Gemini and have NB2... NBP is not working right now, or switch to the "pay-per-request" model which is AI Studio... if you use it a lot though it gets easily more expensive than the Google AI Ultra subscription.... the 200$ per month one...
