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

What this model is

ESRGAN was published by Chinese University of Hong Kong (CUHK),Chinese Academy of Sciences,Nanyang Technological University, in Hong Kong, in September 2018. It comes out of academia,Academia,Academia.

It works in Vision, Image generation, and is recorded as doing image super-resolution.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Answers

ESRGAN — common questions

01

Is ESRGAN open source?

The licensing for ESRGAN was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

02

How many parameters does ESRGAN have?

No parameter count has been published for ESRGAN, which is why no memory or speed figure appears on this page.

03

Who created ESRGAN?

ESRGAN was published by Chinese University of Hong Kong (CUHK),Chinese Academy of Sciences,Nanyang Technological University, based in Hong Kong, categorised as academia,Academia,Academia.

04

When was ESRGAN released?

ESRGAN was published in September 2018. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

What is ESRGAN used for?

ESRGAN works in Vision, Image generation, and is recorded as handling image super-resolution. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

What GPU do I need to run ESRGAN?

None. ESRGAN 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.

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.
