He literally has to EXPLICITLY tell it not to hypersexualize the high school kids it creates.

(At least it made them 18, but god damn...)

Him: "Grok, create two female high school girls that are close friends."
[ten seconds later]
Him: "Holy shit, what the f%$# Grok?!?"

Oh, and every female character created seems to have huge tits BY DEFAULT if you don't explicitly specify breast size.

And the characters it creates... uh... wow...

Put simply... and, in hindsight, this shouldn't surprise anyone... but Grok is SUPER HORNY.

He made a "girlfriend" mode (no scenario, just a "committed" partner)... and every character he created ends up wanting to screw like a porn star in less than a dozen prompts.

It tends to have the character the bot is roleplaying jump into sex readily and enthusiastically, even though there is no prompt anywhere and no driver steering it in that direction.

He says it worked surprisingly well... but, and this is not any of his doing by either what the system prompts are or but what the user says as part of the chat, but all the roleplaying scenarios tend to start veering off towards super-sexual situations.

So he saw that he has access to Grok 4 Fast (don't get me started on that), which is surprisingly reasonably priced and has a <10s response time even for being a reasoning model... so he thought he'd give it a shot and use that to drive the RP bots.
