Though bear in mind that it doesn't insert new information into the model that it didn't have before, it just modifies how the model responds given the information that it already knows.
That's generally a bit of a quibble since "censored" models were still generally trained with the information they're meant to refuse to give - otherwise they wouldn't understand what they're supposed to refuse to do. But worth mentioning in case a situation arises like with AI image models, where some models were trained using image that literally didn't include any genitals in them and as a result no amount of de-censorship is going to help them make crotches that don't look like they were designed by Cronenberg.
