The early models were uncensored, but people seeing early llms give meth recipes and how to make car bombs made them quickly get neutered before public release (additional controls, for pirvate info, nudity, swearing etc all come from additional guardrails and improvements of the protection they can offer the company and not end users)
Have an uncensored model loop through nypost articles and ask it to synthesize content from that. Nypost has tons of scandalous content and can easily get spun into erotica by an uncensored model.
It’s unsafe for that reason, so you absolutely needed both censored and uncensored. It wasn’t an accident.
> can easily get spun into erotica by an uncensored model.
A sexualized fine-tune yes, but that's because you have to make them overly horny to overcome the original censorship.
Nothing prevent them to train a model that will have an appropriate level of sexual content (that is, only upon user explicit request) the same way they train it not to have sexual content at all.
The reason they do that is because they are American companies, the same companies who also censored nude paintings and statues from European museums' pages.
Early models were censored, making uncensored releases have bad optics.
If the first models had been uncensored, no one would care if another was added.
