>>2726137https://novelai.net/The image generator is a paid service, though.
The $10 subscription will give you 1000 Anlas (credits), which should be able to produce 200 images at default settings/resolution, but you will probably want to mess with the settings, and use some features that also cost credits. While you're subscribed, you will be able to purchase more Anlas at a lower price, however.
If you're planning to subscribe, I would recommend the $25 sub, it gives you unlimited generations, BUT only at default settings, while your subscription lasts, plus it gives you 10000 Anlas to spend on generations with altered settings, and the other features.
One last thing, it seems like their model has leaked, so if you have a PC with a good GPU, you might be able to run it for free, but I can't help you with that.
If you need help with anything else, feel free to ask.
