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.

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.

Task
Animal (human/non-human) imitation, Robotic manipulation

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

Parameters
7.1B

"Our system comprises two main components: S2, a VLM backbone, and S1, a latent-conditional visuomotor transformer. S2 is built on a 7B-parameter open-source, open-weight VLM pretrained on internet-scale data. <..> S1, an 80M parameter cross-attention encoder-decoder transformer, handles low-level control." 7B+80M = 7080000000

What the numbers mean

About this model

Helix was published by Figure AI, in United States of America, in February 2025. It comes out of industry.

It works in Robotics, and is recorded as doing animal (human/non-human) imitation, Robotic manipulation.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

Helix — common questions

01

What is Helix used for?

Helix works in Robotics, and is recorded as handling animal (human/non-human) imitation, Robotic manipulation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

02

What GPU do I need to run Helix?

None. Helix 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.

03

Is Helix open source?

No. Helix has not had its weights published, so it exists only as a service controlled by its owner.

04

How many parameters does Helix have?

Helix has 7.1B parameters. "Our system comprises two main components: S2, a VLM backbone, and S1, a latent-conditional visuomotor transformer. S2 is built on a 7B-parameter open-source, open-weight VLM pretrained on internet-scale data. <..> S1, an 80M parameter cross-attention encoder-decoder transformer, handles low-level control." 7B+80M = 7080000000. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

05

Who created Helix?

Helix was published by Figure AI, based in United States of America, categorised as industry.

06

When was Helix released?

Helix was published in February 2025.
