Absolutely not. It’s not “pro” at all, since you can only generate a single image at a time, and the modal that shows while you’re waiting says it can take up to a minute for that single generation.
I don’t do NSFW art with AI though, which seems to perhaps be their main claim to fame, with multiple models being available for that use. Maybe if that’s your intended use case, you might find a different value in it – but still it should offer up to 4 generations at a time like everyone else, or they just end up costing you 4x the amount of time spent waiting.
Plus the files that it outputs for you to download do not include the prompt in the filename, which is also quite annoying. Definite pass on this service.
