A navigable generated world is not a world model
Naval pushes back on how the term world model is being used. Generating something that looks like a world you can wander around in is not a world model. A world model is an agent carrying an internal model of the world that lets it act, predict the consequences of its actions and adjust its behaviour from what happened, in a reinforcement-learning loop. He also grades current AI as jagged and weak at multimodal reasoning.
- Common confusion: visual navigable output mistaken for an internal model.
- Real test is predict, act, observe, adjust.
- Naval calls today's AI jagged in intelligence and poor at multimodal reasoning.
- New kinds of models, agents and intelligence are emerging, including Yann LeCun's recent work.
“The AI that I'm seeing at has jagged intelligence. It's also pretty bad at multimodal reasoning.”
“A world model is when you have an agent that has a model of the world inside its head, which allows it to take actions…”
