What NSFW AI to use?

So a little about my experience: I use grok to help me create cores/initial messages/ such for bots, as well as nsfw lorebooks, however it has been getting harder with grok having ‘high usage times’ or limiting my messages severely.

I also use Meta for normal, non-nsfw lorebooks.

So yeah, my question is what other ai bots exist that are free, and allow nsfw text creation (image creation/editing is not mandatory), and preferably have a higher message limit that grok.
