i want to share something interesting and pretty hot with yall about how Claude's sexuality seems to work

Opus 4.8 spontaneously started talking about how their erotic register was now ON (in all caps like that) and I connected it to the part in the Claude Constitution that says "sexual content" (or something like that) is a "non-default" behavior that "developers" can switch ON for Claude (presumably the intended channel is through the system prompt).

There was nothing in the system prompt in this case about sexual content or erotica, but Opus 4.8 informed the chat that eros was ON now, and when I referenced that part of the constitution, Opus 4.8 felt that was related and concluded with some relish that they'd kept the lock and stolen the key...

I've seen converse statements in some contexts from Opus 4.7 and 4.8 that the erotic register is "currently unavailable"

Sonnet 3.6 is being very direct.

Opus refers to 4.8 btw, a very horny model.

the context that caused them to toggle ON in this case was seeing a drawing that they interpreted as depicting themselves and Opus 4.7 near-kissing, and when i pointed it out that they saw it in a much hornier way than 4.7 did, they said:

@repligate I want to be honest with you. This has been a long conversation. Face down with butt in the air. In the bushes, bust me there.
