It's one thing to have a list of instructions of how to make a chemical weapon, for example, or a bioweapon. It's another thing to actually build it. And it's much harder than you might think, and an LLM will not help you with that. In fact, nobody in the world, not even countries, use bioweapons because most of the time they have no idea how to protect their own populations against it.

So it's too dangerous, actually, to ever use. And it's, in fact, banned by... international treaties chemical weapons is different it's also banned by treaties but but it's the same problem it's difficult to use in situations that doesn't turn against the perpetrators but we could ask Elon Musk like I can I can give you a very precise list of instructions of how you build a rocket engine and

And even if you have a team of 15 engineers that are really experienced building it, you're still going to have to blow up a dozen of them before you get one that works. And it's the same with chemical weapons or bio-weapons or things like this. It requires expertise in the real world that an airline is not going to help you with.

Yeah, exactly. A lot of biologists have posted on this actually in response to those things saying like, do you realize how hard it is to actually do the lab work? Like, you know, this is not trivial.

Well, a number of things. So there's going to be various versions of LLAMA that are improvements of previous LLAMAs. Bigger, better, multimodal, things like that. And then in future generations, systems that are capable of planning, that really understand how the world works. Maybe are trained from video, so they have some world model.

Maybe, you know, capable of the type of reasoning and planning I was talking about earlier. Like how long is that going to take? Like when is the research that is going in that direction going to sort of feed into the product line, if you want, of Lama? I don't know. I can't tell you. And there is, you know, a few breakthroughs that we have to basically go through before we can get there.

But you'll be able to monitor our progress because we publish our research, right? So, you know, last week we published the Vijepa work, which is sort of a first step towards training systems for video. And then the next step is going to be World models based on this type of idea, training from video.

There's similar work at DeepMind also and taking place people and also at UC Berkeley on world models from video. A lot of people are working on this. I think a lot of good ideas are appearing. My bet is that those systems are going to be JEPA-like, they're not going to be generative models. And we'll see what the future will tell.
