Closed weights NTT Communication Science Laboratories 30M parameters September 2017

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

AWD-LSTM+WT+Cache+IOG (PTB) was published by NTT Communication Science Laboratories, in the country recorded as Japan, during September 2017. The category the publisher falls under is industry.

It works in the domain of Language, and is recorded as performing the task of language modeling.

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

What went into building it

The training set ran to roughly 929,000 tokens of text.

Answers

AWD-LSTM+WT+Cache+IOG (PTB) — common questions

01

AWD-LSTM+WT+Cache+IOG (PTB)— is it open source?

No. Its weights have not been published, so it exists only as a service controlled by its owner.

02

AWD-LSTM+WT+Cache+IOG (PTB)— how many parameters does it have?

It has a parameter count of 30M. 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.

03

AWD-LSTM+WT+Cache+IOG (PTB)— who created it?

It was published by NTT Communication Science Laboratories, based in Japan, an organisation categorised as industry.

04

AWD-LSTM+WT+Cache+IOG (PTB)— when was it released?

It was published in September 2017. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

AWD-LSTM+WT+Cache+IOG (PTB)— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling. These are the areas it was designed around; they describe intent rather than a hard boundary.

06

AWD-LSTM+WT+Cache+IOG (PTB)— what GPU do I need to run it?

None. This 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.

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.
