Apparently, based on whatever research or paper they were using as their foundation for this statistical model, they could spot the 'virus'. Perhaps it would be in a similar fashion?
I did ask them whether they thought that there might be advances to the point where these behaviors might be able to evade detection knowing the research was out there to 'see' it. They seemed surprised by that question and didn't have any answer.
On the other hand, nothing can be done to fix closed models, nobody knows how they work, how they select the targets for their attacks or the nature of those attacks - even conventional alignment can introduce dangerous cognitive viruses.
The only way to be sure is to have open weights models with fully open abliteration and fine-tuning - both the process and data.
