1X World Model
No estimate
No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean
Where it came from
1X World Model was published by 1X, in United States of America, in September 2024. The organisation is categorised as industry.
It works in Robotics, Video, and is recorded as doing robotic manipulation, Video generation, Animal (human/non-human) imitation.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
1X World Model — common questions
Is 1X World Model open source?
No. 1X World Model has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does 1X World Model have?
No parameter count has been published for 1X World Model, which is why no memory or speed figure appears on this page.
Who created 1X World Model?
1X World Model was published by 1X, based in United States of America, categorised as industry.
When was 1X World Model released?
1X World Model was published in September 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is 1X World Model used for?
1X World Model works in Robotics, Video, and is recorded as handling robotic manipulation, Video generation, Animal (human/non-human) imitation. These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run 1X World Model?
None. 1X World Model is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
