BPE

Closed weights University of Edinburgh August 2015

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.

Translation

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

Training data
50,000,000 tokens

[WORDS] "We perform experiments on data from the shared translation task of WMT 2015. For English→German, our training set consists of 4.2 million sentence pairs, or approximately 100 million tokens. For English→Russian, the training set consists of 2.6 million sentence pairs, or approximately 50 million tokens" 100M tokens, around half will be in English, 0.75 words per token

What the numbers mean

Where it came from

BPE was published by University of Edinburgh, in United Kingdom of Great Britain and Northern Ireland, in August 2015. It comes out of academia.

It works in Language, and is recorded as doing translation.

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

How it was trained

Around 50,000,000 tokens went into training it.

The reason it appears in this catalogue at all is highly cited.

Answers

BPE — common questions

01

Who created BPE?

BPE was published by University of Edinburgh, based in United Kingdom of Great Britain and Northern Ireland, categorised as academia.

02

When was BPE released?

BPE was published in August 2015. 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 BPE used for?

BPE works in Language, and is recorded as handling translation. These are the areas it was designed around; they describe intent rather than a hard boundary.

04

What GPU do I need to run BPE?

None. BPE 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 BPE open source?

The licensing for BPE was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

06

How many parameters does BPE have?

No parameter count has been published for BPE, 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.
