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.

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.

What the numbers mean

Background

4 layer Densely Connected LSTM 14M (PTB) was published by Ghent University, in Belgium, in July 2017. It comes out of 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.

How it was trained

The training run consumed about 7.8 × 10¹⁵ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Answers

4 layer Densely Connected LSTM 14M (PTB) — common questions

01

Is 4 layer Densely Connected LSTM 14M (PTB) open source?

No. 4 layer Densely Connected LSTM 14M (PTB) has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does 4 layer Densely Connected LSTM 14M (PTB) have?

4 layer Densely Connected LSTM 14M (PTB) has 14M parameters. 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

Who created 4 layer Densely Connected LSTM 14M (PTB)?

4 layer Densely Connected LSTM 14M (PTB) was published by Ghent University, based in Belgium, categorised as academia.

04

When was 4 layer Densely Connected LSTM 14M (PTB) released?

4 layer Densely Connected LSTM 14M (PTB) was published in July 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

What is 4 layer Densely Connected LSTM 14M (PTB) used for?

4 layer Densely Connected LSTM 14M (PTB) works in Language, and is recorded as handling language modeling. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

06

How much compute was used to train 4 layer Densely Connected LSTM 14M (PTB)?

Around 7.8 × 10¹⁵ FLOP. 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.

07

What GPU do I need to run 4 layer Densely Connected LSTM 14M (PTB)?

None. 4 layer Densely Connected LSTM 14M (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.

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.
