The porn / sex-chat one is really disappointing. It seems they've given up even pretending that they are trying to do something beneficial for society. This is just a pure society-be-damned money grab.
Tell that to the thousands of 18 year olds who'll be captured by this predatory service and get AI psychosis
So, it's not a matter of them not being able to do a good job of preventing the model from doing it, therefore giving up and instead encouraging it to do it (which anyways makes no sense), but rather them having chosen to train the model to do this. OpenAI is targetting porn as one of their profit centers.
I don't know about the former, but the latter absolutely has sexually explicit material that could make the model more likely to generate erotic stories, flirty chats, etc.
