Excited to introduce Dreamer 4, an agent that learns to solve complex control tasks entirely inside of its scalable world model! 🌎🤖 Dreamer 4 pushes the frontier of world model accuracy, speed, and learning complex tasks from offline datasets. co-led with @wilson1yan

Proud to share that I've been recognized as one of the 35 Innovators under 35 by MIT Technology Review! Developing world models has been an incredible journey over the past 8 years, both training the world models and leveraging them for imagination training and motor control 🌎

Really enjoyed this conversation on the BuzzRobot podcast! 🤖⚡ We covered a lot of ground on the future of the field: - the path from frontier models to AGI - discovering instead of distilling reasoning - continual learning - scalable objectives - how to solve robotics

Key points from my recent conversation with @danijarh - Architecture doesn’t matter to achieve AGI. What is missing: algorithmic advances and objective function improvements. More compute still matters. - AI shouldn’t be limited by human reasoning. It will be able to go beyond
