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.

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.

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

Where it came from

DALL-E was published by OpenAI, in United States of America, in January 2021. The organisation is categorised as 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.

What went into building it

Producing it required around 4.7 × 10²² FLOP of arithmetic, on NVIDIA Tesla V100 DGXS 16 GB, which is a statement about the training budget rather than about inference.

The training set ran to roughly 320,000,000,000 tokens.

Its inclusion criterion is significant use,Highly cited,Historical significance.

Answers

DALL-E — common questions

01

When was DALL-E released?

DALL-E was published in January 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

02

What is DALL-E used for?

DALL-E works in Image generation, and is recorded as handling text-to-image, Image generation. 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.

03

How much compute was used to train DALL-E?

Around 4.7 × 10²² FLOP, on NVIDIA Tesla V100 DGXS 16 GB. 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.

04

What GPU do I need to run DALL-E?

None. DALL-E 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 DALL-E open source?

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

06

How many parameters does DALL-E have?

DALL-E has 12B parameters. DALL·E is a 12-billion parameter version of GPT-3 trained to generate images from text descriptions. 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.

07

Who created DALL-E?

DALL-E was published by OpenAI, based in United States of America, categorised as industry.

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.
