Closed weights Google Research 3B parameters November 2021

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.

How it is classified

Labels the source dataset applies when tracking notable models, and how confident it is in the entry.

Why it is tracked
SOTA improvement

"For example, it achieves 82.5% accuracy on the challenging ObjectNet test set [1], outperforming the previous state-of-the-art method [46] by 10.2%."

What the numbers mean

Background

ViT-G/14 (LiT) was published by Google Research, in United States of America, in November 2021. The organisation is categorised as industry.

It works in Vision, and is recorded as doing image classification.

Its starting point was ViT-G/14 — most models at this scale are adapted from an existing base rather than built from nothing.

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

What went into building it

It was trained on about 1,040,000,000,000 tokens of text.

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

Answers

ViT-G/14 (LiT) — common questions

01

What is ViT-G/14 (LiT) used for?

ViT-G/14 (LiT) works in Vision, and is recorded as handling image classification. These are the areas it was designed around; they describe intent rather than a hard boundary.

02

What GPU do I need to run ViT-G/14 (LiT)?

None. ViT-G/14 (LiT) 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.

03

Is ViT-G/14 (LiT) open source?

No. ViT-G/14 (LiT) has not had its weights published, so it exists only as a service controlled by its owner.

04

How many parameters does ViT-G/14 (LiT) have?

ViT-G/14 (LiT) has 3B parameters. Table 7. 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.

05

Who created ViT-G/14 (LiT)?

ViT-G/14 (LiT) was published by Google Research, based in United States of America, categorised as industry.

06

When was ViT-G/14 (LiT) released?

ViT-G/14 (LiT) was published in November 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.

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.
