0:00 One of the big questions on people's minds these days is AI doing bad things. As someone that watches these models think and operate, why is it so hard to catch it thinking badly trying to deceive us? >> We trained Claude to be helpful, harmless, and honest. Is it the case that it's behaving well, but if you look inside, actually, it's like, oh, I'm only behaving well cuz Lenny's watching right now. >> People's full-time jobs is studying the model, how it thinks, how it operates. How long has this been a skill set in a job? One of the most important things to realize if you like use language models or think about them is just this like very bizarre fact that to make them is
0:30 not to understand them. All these models do is just a lot of mathematical operations on many numbers. If you look at it, it makes no sense. You just have a list of a 100 numbers. You know, the model's doing math and then you just try to see if there's patterns. >> You are figuring it out the same way we figure out how the brain works. Looking for patterns. You show this image. This part of the brain lights up and you're doing the exact same thing with AI. Wow, this is [laughter] so fascinating. >> There was this model we were training. It would go crazy. It would do some math. It would get to an answer. I think it was 12. It would immediately go back and say like, "Oh no, oh my god, the answer actually is for sure 36." It
