GigaGAN
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.

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

- Task
- Text-to-image, Image generation
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.

Training compute
The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

What the numbers mean
About this model
GigaGAN was published by POSTECH,Carnegie Mellon University (CMU),Adobe, in Korea (Republic of), in June 2023. The organisation is categorised as academia,Academia,Industry.
It works in Image generation, and is recorded as doing text-to-image, Image generation.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Training and provenance
Producing it required around 3.9 × 10²² FLOP of arithmetic, which is a statement about the training budget rather than about inference.
Around 1,960,000,000 tokens went into training it.
Answers
GigaGAN — common questions
How much compute was used to train GigaGAN?
Around 3.9 × 10²² FLOP. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.
What GPU do I need to run GigaGAN?
None. GigaGAN 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 GigaGAN open source?
No. GigaGAN has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does GigaGAN have?
GigaGAN has 1B parameters. 1B (Table 2). 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 GigaGAN?
GigaGAN was published by POSTECH,Carnegie Mellon University (CMU),Adobe, based in Korea (Republic of), categorised as academia,Academia,Industry.
When was GigaGAN released?
GigaGAN was published in June 2023. 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 GigaGAN used for?
GigaGAN works in Image generation, and is recorded as handling text-to-image, Image generation. 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.
