> The company that manages to produce a well-labeled, porn-tuned AI image model is going to absolutely clean up.

For anime/non-photographic content that essentially exists (Pony, then Illustrious, then probably some new-fangled thing by now that I don't even know about), thanks to the meticulously tagged booru image corpus. However, as strong as these models are on matters of anatomy and kinks, they're limited in other ways due to the hugely biased dataset and dependence on tag soup prompts rather than natural language (many find the latter a plus, not a minus, though).

I haven't heard of any proprietary/cloud-based NSFW model that would be massively better than what's available for free. There are many NSFW-friendly services, but by and large they're just frontends to models trained by other people.
