Ok, so I started messing with Grok after this thread, and whilst I can get it to generate very big breasted models, and even some pretty decent BE, some of them won't even animate if it thinks they're too spicy, so I really have no idea how you're getting it to generate nipples.
Well, first I won't animate any image that shows vagina or even camel toe. That is an immediate censoring. Also, I don't mention nipples in my prompts. I keep them very PG and let Grok spice things up. The only time I even mention breasts in a prompt is for BE. I say "chest". Also, it seems once you generate enough that don't get censored, it is easier to get things through. I had 2 videos actually show vagina without being censored. I also didn't prompt for it and it wasn't in the original picture. Just a pleasant surprise.
Punchy
Turns out that wasn't even the issue. Most of my images (generating with the scrolling bit) were blurred out, and even pretty tame ones wouldn't even animate with the normal setting, just "Content moderated, choose another prompt".
The problem?
The UK government and it's fucking stupid online safety bill.
Our Grok is heavily censored (can still get some
excellent BE roleplay from it though) but the images are very hard to do anything with other than a bit of jiggling and
maaaybe some BE if you word it right (and not too big).
Solution?
VPN.
Put me in Netherlands and all of a sudden the girls I've saved in my favourites all can't wait to get their tits out, even in "normal" animation setting and
it is glorious.
All the scrolling image generation is completely uncovered, and I'm pained to think about what I've missed from previous prompts.
I've had perfectly good results using terms such as 'breasts', 'ass' and 'nipples', but being safe with terms such as 'swell', 'inflate' (banned in the UK that one) and 'increase'.
In fact, when modifying an already generated picture I simply wrote "increase breast size 5000%" pressed the normal generation button and she nearly fell over.
I'm also partial to some larger girls and it has no problem accepting higher weights (can only double weight in UK version)
What a powerful tool, good job you can use it one handed...

Oh, and hilariously, logging in to Grok without the VPN, still has the uncensored images in my favourites. Bet I won't be able to modify them though.
