A fantastic site for all your AI needs. You can use multiple models like Grok, Flux, Seedream etc at pretty reasonable costs. Unlike with the native Grok site where a failed generation while eat into you allotment a failed generation will not cost you credits. The packages range from free (300 credits a month) all the way up to ultra (130k credits per month) at an eye watering $125 dollars per month. Personally I use the basic tier (10k per month) at a reasonable $10 per month. But that's not all, you can upscale, edit, use image to image, make videos, music, use an AI assistant, access free images and BGM and to top it off there is a genuinely nice community with various sub-groups for different art styles, ideas etc (essentially like a QT group on X).
In conclusion there are always new models, features and toys to play with. Absolutely worth your time.
