SkyReels-A1
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
SkyReels-A1 was published by Kunlun Inc., in the country recorded as China, during February 2025. It comes out of an organisation categorised as industry.
It works in the domain of Video, and is recorded as performing the task of video generation, Image-to-video.
It builds on CogVideoX. Most models at this scale are adapted from an existing base rather than built from nothing.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
SkyReels-A1 — common questions
SkyReels-A1— how many parameters does it have?
No parameter count has been published for it, which is why no memory or speed figure appears on this page.
SkyReels-A1— who created it?
It was published by Kunlun Inc., based in China, an organisation categorised as industry.
SkyReels-A1— when was it released?
It was published in February 2025.
SkyReels-A1— what is it used for?
It works in the domain of Video, and is recorded as handling the task of video generation, Image-to-video. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
SkyReels-A1— what GPU do I need to run it?
None. This 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.
SkyReels-A1— is it open source?
The licensing was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
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.
