Researchers have developed Flex-$\pi$, a 6-billion parameter world-action model that integrates 3D geometry and object semantics alongside RGB data. This model leverages a pre-trained video-generation VAE to encode 3D pointmaps without additional training, allowing for a unified latent space. Flex-$\pi$ utilizes a Mixture-of-Transformers backbone with cross-modality forcing, enabling it to operate efficiently across various subsets of its input streams. The model demonstrates significant improvements in demonstration efficiency and generalization for real-world bimanual manipulation tasks, outperforming existing baselines. AI
IMPACT This model's ability to integrate diverse visual signals efficiently could advance robotics and manipulation tasks by improving generalization and reducing data requirements.
