It sure seems like this is two different techniques/technologies at work. There is a CSAM deterctor using a known database and then, it looks like, there is a separate model in messages for detecting pornographic content without a known database.

It doesn't sound like it can "detect pornographic content" since the difference between pornography and nudity is not going to be reducible to a coefficient matrix.
