Well, so no, you will have to build a specific architecture to allow for hierarchical planning. So hierarchical planning is absolutely necessary if you want to plan complex actions. If I want to go from, let's say, from New York to Paris, it's the example I use all the time, and I'm sitting in my office at NYU, my objective that I need to minimize is my distance to Paris at a high level.

a very abstract representation of my location, I would have to decompose this into two sub-goals. First one is go to the airport. Second one is catch a plane to Paris. Okay, so my sub-goal is now going to the airport. My objective function is my distance to the airport. How do I go to the airport? Well, I have to go in the street and hail a taxi, which you can do in New York.

Okay, now I have another sub-goal. Go down on the street. What that means, going to the elevator, going down the elevator, walk out the street. How do I go to the elevator? I have to... Stand up from my chair, open the door of my office, go to the elevator, push the button. How do I get up from my chair?

Like, you know, you can imagine going down, all the way down to basically what amounts to millisecond by millisecond muscle control. Okay. And obviously you're not going to plan your entire trip from New York to Paris in terms of millisecond by millisecond muscle control. First, that would be incredibly expensive.

But it will also be completely impossible because you don't know all the conditions of what's going to happen. How long it's going to take to catch a taxi or to go to the airport with traffic. You would have to know exactly the condition of everything to be able to do this planning. And you don't have the information.

So you have to do this hierarchical planning so that you can start acting and then sort of replanning as you go. And nobody really knows how to do this in AI. Nobody knows how to train a system to learn the appropriate multiple levels of representation so that hierarchical planning works.

Right, so there's a lot of questions that are actually implied by this, right? So the first thing is, LLMs will be able to answer some of those questions down to some level of abstraction. under the condition that they've been trained with similar scenarios in their training set.
