mimic-video: Video-Action Models for Generalizable Robot Control Beyond VLAs
The paper introduces mimic-video, a novel class of Video-Action Models (VAMs) that significantly advance robot control by integrating pre-trained internet-scale video models with flow matching-based action decoders. Unlike traditional Vision-Language-Action (VLA) models that learn physical dynamics from scratch, mimic-video leverages the inherent visual dynamics encoded in video backbones to achieve superior sample efficiency (10x faster) and faster convergence (2x faster) on dexterous manipulation tasks, both in simulation and real-world environments. This approach decouples long-horizon planning to the video backbone and simplifies low-level control, making robot learning more efficient and robust.

Robotics & AI
This research in Robotics & AI presents a significant leap forward in robot control methodologies. By leveraging the rich, dynamic information embedded in pre-trained video models, mimic-video addresses fundamental limitations of traditional Vision-Language-Action (VLA) models that struggle with inherent physical understanding. This innovation is crucial for developing robots that can perform complex manipulation tasks with unprecedented efficiency and generalization in dynamic, real-world environments. The decoupling of high-level planning from low-level control, facilitated by video backbones, streamlines the learning process, making AI-driven robotics more accessible and robust for enterprise applications.
VAM
A new class of robot policies that grounds control directly in latent representations of pre-trained generative video models.
Decoupled Learning for Enhanced Robot Control
The mimic-video approach introduces Decoupled Learning, a paradigm that separates complex, long-horizon planning from low-level control. The pre-trained video backbone, rich in visual dynamics, handles the high-level visual planning. Subsequently, a lightweight action decoder functions as an Inverse Dynamics Model (IDM) to generate precise low-level motor commands from these visual plans. This clear separation allows each component to specialize, leading to more robust and sample-efficient policy learning, unlike traditional VLA models that attempt to learn all dynamics from scarce robot data.
Partial Denoising
Extracts semantic features from intermediate flow states of the video model without full pixel reconstruction, mitigating distribution shift and accelerating inference.

Real-World Impact: Dexterous Bimanual Manipulation
The paper demonstrates mimic-video's performance on a real-world bimanual robot setup with Franka Emika Panda arms and custom dexterous hands. For tasks like 'Package sorting' and 'Measuring Tape Stowing', mimic-video achieves state-of-the-art success rates (72.0% for Packing, 93.0% for Package handover) even with extremely scarce task-specific data (1-2 hours of demonstrations). This highlights its ability to bridge visual uncertainty due to occlusions and learn robust policies efficiently by leveraging the generative video prior.
