Why did the recent Hugging Face hack spark a wave of AI‑safety concerns?
Hey, I'm Flora and you're listening to Science Friday. For the last few weeks, AI safety has dominated the news cycle, precipitated in part by an AI attack where a bunch of OpenAI's agents teamed up and hacked another AI platform, Hugging Face, without humans knowing. Since then, multiple AI researchers have come forward to say how worried they are that this tech is unsafe. Now, every day it seems like there's a new development. So, how do we make sense of what's happening in AI research right now? Today we're going to focus on the engineering of AI safety. And we wanted to hear from experts outside of the hype machine of Silicon Valley, outside of the major AI companies, scientists who are doing the dirty work of figuring out what developing safer AI even means.
Here with us today is Dr. Andrea Lincoln, a computer science professor at Boston University and an advisory board member for the Alignment Project at the AI Security Institute. She studies how to mathematically understand the internal processes of AI models. And Dr. Vinod Vaikuntanatan, a cryptographer at MIT and a founding member of the Institute for Responsible Superintelligence. He researches trust and security concerns. Andrea Vinaud, welcome to Science Friday.
Great to be here.
Thank you. I wanna talk about some of the words we've been hearing because They feel vague to me or metaphorical and I wanna understand them more deeply. So let's start with alignment. What does it mean to align an AI system, Andrea?
That's a great question. Um it's uh a term of art that doesn't have a super crisp mathematical definition. However, it's a name for, I'll say, like a research project that is trying to have models that, you know, are capable of complex, intelligent, seeming behavior. while having those models, fundamentally pursuing goals that you intended them to have. There's been some really interesting work on trying to get, you know, crisp theoretical definitions of what it means to have goals. There's been interesting work on uh trying to solve these problems with debate, um, uh which is like a particular like sort of mathematical research agenda. There are a bunch of things. Wait, debate is a
mathematical research agenda.
Yes, um uh this is one of many research directions where The goal is basically to uh you know have different models debate uh and then have uh the outcomes that you can pull from those models. to to use the debate itself to like check whether or not the models are getting the right answer, and then turn that into something that mechanically you can trust um in a wide set of areas is the the goal of the research agenda of debate. All of these research agendas haven't yet resulted in a full solution, um, unfortunately, but uh The alignment project is fundamentally one of Can you get a system that's more capable controlled by a system that's less capable? And there exists Is that us, the system that's less capable?
Yes, humanity is the less capable system here. And the real practical version of this problem is quite messy and difficult. Um
What does “AI alignment” actually mean and why is it hard to define?
Vinoda, I'm curious what what your take on this is.
Yeah, so Flora, you started with the hardest question of all, uh, right, which is how to define alignment. It's much harder to define when a model is aligned uh versus when it is not aligned. So that is easy to understand. Uh you know, I can give you examples and you say, well, you know, uh there's the classic paperclip example, right? Uh which is sort of like an imaginary scenario where you train a model to design a factory that maximize. Maximizes the number of paper clippers it produces. And it ends up sort of deciding that the best way to do this is to turn. all carbon-based living forms into paperclips.
It goes off the rails. It takes it very literally. Right.
It does it. It actually does maximize the number of paper clips. But but you know what? Uh not in a way that was favorable to us. So that is clearly not aligned. You know, one can keep coming up with examples of behaviors of models that are not aligned. And that is easy to understand.
