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

EGRU (PTB) was published by Ruhr University Bochum,Technische Universität Dresden,University of London, in Germany, in June 2022. It comes out of academia,Academia,Academia.

It works in Language, and is recorded as doing language modeling.

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

Training and provenance

The training set ran to roughly 1,238,667 tokens.

Answers

EGRU (PTB) — common questions

01

What is EGRU (PTB) used for?

EGRU (PTB) works in Language, and is recorded as handling language modeling. These are the areas it was designed around; they describe intent rather than a hard boundary.

02

What GPU do I need to run EGRU (PTB)?

None. EGRU (PTB) 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 EGRU (PTB) open source?

No. EGRU (PTB) has not had its weights published, so it exists only as a service controlled by its owner.

04

How many parameters does EGRU (PTB) have?

EGRU (PTB) has 55M parameters. Table 3. 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 EGRU (PTB)?

EGRU (PTB) was published by Ruhr University Bochum,Technische Universität Dresden,University of London, based in Germany, categorised as academia,Academia,Academia.

06

When was EGRU (PTB) released?

EGRU (PTB) 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.

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.
