Fuyu-Heavy
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 it does
The problem areas the model was built for. A model can carry several of each.
- Domain
- Multimodal, Language, Vision
- Task
- Chat, Language modeling/generation, Visual question answering, System control
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
- 100B
- Training data
- tokens
"Fuyu-Heavy is the world’s third-most-capable multimodal model, behind only GPT4-V and Gemini Ultra, which are 10-20 times bigger" So possibly around ~100B params, though GPT-4/Gemini params aren't public

What the numbers mean
Background
Fuyu-Heavy was published by Adept, in United States of America, in January 2024. It comes out of industry.
It works in Multimodal, Language, Vision, and is recorded as doing chat, Language modeling/generation, Visual question answering, System control.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Answers
Fuyu-Heavy — common questions
What GPU do I need to run Fuyu-Heavy?
None. Fuyu-Heavy 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.
Is Fuyu-Heavy open source?
No. Fuyu-Heavy has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Fuyu-Heavy have?
Fuyu-Heavy has 100B parameters. "Fuyu-Heavy is the world’s third-most-capable multimodal model, behind only GPT4-V and Gemini Ultra, which are 10-20 times bigger" So possibly around ~100B params, though GPT-4/Gemini params aren't public. 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.
Who created Fuyu-Heavy?
Fuyu-Heavy was published by Adept, based in United States of America, categorised as industry.
When was Fuyu-Heavy released?
Fuyu-Heavy was published in January 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 Fuyu-Heavy used for?
Fuyu-Heavy works in Multimodal, Language, Vision, and is recorded as handling chat, Language modeling/generation, Visual question answering, System control. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
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.
