1X turns its video world model into a robot policy for NEO
On 2026-01-12 1X showed the 1X World Model (1XWM) acting as NEO's policy: a 14B video model imagines the next ~5 s from a text prompt and an inverse-dynamics model turns that video into robot actions, letting the home humanoid attempt some objects and motions absent from its robot training data.
Key facts
- Backbone: 14B generative video model fine-tuned for NEO; ~11 s per rollout (multi-GPU inference with Verda)
- Data: ~900 h egocentric human video + ~70 h NEO data; 400 h unfiltered robot data for the inverse-dynamics model
- Grasping ~80% success; pouring 0%; best-of-8 generation lifted 'pull tissue' from 30% to 45%
- Earlier 1XWM (June 2025) was used only to evaluate policies
What happened
1X published a world-model-based policy for its NEO home humanoid. Instead of mapping pixels directly to actions, the model generates a short future video of the task and extracts actions from it. 1X presents this as its path to reducing reliance on teleoperation.
Why it matters
It is one of the first deployments of a large video-generation model as a humanoid control policy, part of the 2026 shift toward learning robot skills from human video. Slow inference and weak dexterous results show the limits.

Summary
In this official video from 1X Technologies, team members Jack Monas and Christina Yu introduce the 1X World Model, a deep generative neural network acting as a digital twin of the physical world. They explain how the model simulates real-world physics and robot interactions to evaluate and improve autonomous policies for the humanoid robot NEO without requiring endless physical trials.
What is shown
- [00:00] Intro sequence featuring a humanoid robot (NEO) standing before a curved bank of CRT monitors displaying camera feeds.
- [00:28] Jack Monas in an outdoor forest setting explaining the challenge of evaluating general-purpose robotics models.
- [00:33] Real-world clips of NEO handing a beverage bottle to a person and unloading clothes from a washing machine.
- [00:54] Side-by-side comparison on a monitor marked "REAL" versus "GENERATION" predicting robot viewpoints during washing machine interaction.
- [01:06] Christina Yu discussing data collection alongside video feeds showing household tasks.
- [01:14] Visualizations labelled "WORLD MODEL GENERATION" demonstrating modeled physics: cloth manipulation, cabinet collisions, and sink counter interactions.
- [01:36] An accuracy vs. dataset size scaling graph showing steady performance gains as training data increases.
- [01:51] Policy evaluation comparison across three monitors (Policy A with WM score 0.21, Policy B with 0.65, Policy C with 0.98).
- [02:29] Demonstration of NEO’s compliant design as an engineer leans against and touches the robot's torso.
- [02:41] Conceptual animation depicting the world model integrated into NEO’s cognitive architecture for real-time planning.
Claims & numbers
- Jack Monas claims traditional physical evaluation of general-purpose robotics models corresponds to "a lifetime of experience in the real world" that the world model compresses into "an instant."
- Christina Yu states the 1X World Model is trained on "thousands of hours of robot interaction captured from raw sensory data."
- The presenters state the model accurately simulates delicate object grasping, rigid body collisions, and deformable object manipulation.
- Jack Monas notes that evaluating foundation models like Redwood via the world model cuts iteration cycle times from "weeks to minutes."
- Christina Yu highlights that while web video, first-person human video, and teleoperation were tested, autonomous robot exploration (including failure modes) proved to be the most vital training data.
Notable quotes
- [00:43] Jack Monas: "That's why we built the 1X World Model, which serves as a bridge between atoms and bits."
- [01:03] Christina Yu: "The 1X World Model tackles the complexity of the real world by learning directly from thousands of hours of robot interaction captured from raw sensory data."
- [01:59] Jack Monas: "The world model lets us evaluate its capabilities with measurable results, shortening our iteration speed from weeks to minutes."
Assessment
This is an official announcement and architecture overview video from 1X Technologies. It mixes real-world footage of NEO manipulating domestic objects with retro-styled CRT visual effects and model generation clips; while benchmark scores and scaling curves are presented, full algorithmic and technical verification details are left to accompanying documentation.
