Closed weights OpenAI February 2024

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

Background

Sora was published by OpenAI, in United States of America, in February 2024. The organisation is categorised as industry.

It works in Video, Vision, and is recorded as doing video generation, Text-to-video, Image-to-video, Video-to-video.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

How it was trained

The reason it appears in this catalogue at all is sOTA improvement.

Answers

Sora — common questions

01

Who created Sora?

Sora was published by OpenAI, based in United States of America, categorised as industry.

02

When was Sora released?

Sora was published in February 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.

03

What is Sora used for?

Sora works in Video, Vision, and is recorded as handling video generation, Text-to-video, Image-to-video, Video-to-video. These are the areas it was designed around; they describe intent rather than a hard boundary.

04

What GPU do I need to run Sora?

None. Sora 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.

05

Is Sora open source?

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

06

How many parameters does Sora have?

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

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.
