"By default, all models are trained on paired image-text data used in [16], consisting of 3.6B images and alt-texts scraped from the web. For large LIMoE-H/14 experiment, we also co-train with JFT-4B [17]." "The largest scale model is trained at batch size 21502, with resolution 288 and text sequence length 16." "The model was trained for 700k steps pre-cooldown. There was one cooldown of length 125k steps from the final step, and 3 of length 40k steps starting from step 650k" 21502*288*70000…

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.

Assume C = 6*N*D. C = 6*675e6*21.5e3*1e6*(16+(288/14)**2)/2 = 1.8e22 This is broadly consistent with ViT-H/14's c…

What the numbers mean

About this model

LIMoE-H/14 was published by Google, in United States of America, in June 2022. The organisation is categorised as industry.

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

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

Training and provenance

Training it took roughly 1.8 × 10²² FLOP of computation, on Google TPU v2,Google TPU v3,Google TPU v4 — a measure of what producing the model cost, not of how fast it answers.

The training set ran to roughly 4,575,625,612,000 tokens.

Answers

LIMoE-H/14 — common questions

01

When was LIMoE-H/14 released?

LIMoE-H/14 was published in June 2022. 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 LIMoE-H/14 used for?

LIMoE-H/14 works in Multimodal, Vision, Language, and is recorded as handling image classification. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

03

How much compute was used to train LIMoE-H/14?

Around 1.8 × 10²² FLOP, on Google TPU v2,Google TPU v3,Google TPU v4. 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 LIMoE-H/14?

None. LIMoE-H/14 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 LIMoE-H/14 open source?

No. LIMoE-H/14 has not had its weights published, so it exists only as a service controlled by its owner.

06

How many parameters does LIMoE-H/14 have?

LIMoE-H/14 has 5.6B parameters. Section 1: "We scale this up to a large 5.6B parameter LIMoE-H/14". 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 LIMoE-H/14?

LIMoE-H/14 was published by Google, based in United States of America, categorised as industry.
