1X Establishes 1X World Model Lab to Research World Models for Fully Autonomous Humanoids

On June 4, 2026, 1X announced that it had established a new research organization, 1X World Model Lab, to accelerate the development of fully autonomous humanoids. The organization will focus on pretraining large-scale embodied world models, drawing on diverse data sources, including video, first-person human experiences, interaction data, simulations, robot data collected through teleoperation, and on-policy NEO data. Sam Sinha, a founding research scientist at Luma AI who led the scaling of multimodal generative video models, has joined as founding AI researcher and head of world models.

For humanoid researchers and developers of foundation models for robots, the significance is that 1X has outlined an approach that combines video, first-person human actions, simulation, robot data collected through teleoperation, and data from NEO operating on-policy from the outset of pretraining, rather than relying on later-stage fine-tuning. 1X says this approach enabled robots to perform unfamiliar tasks without additional prior training, specifying the data it aims to use to achieve generalization beyond individual tasks in static environments.
