AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB)

Closed weights Salesforce Research 24M parameters August 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.

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

About this model

AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) was published by Salesforce Research, in United States of America, in August 2017. It comes out of industry.

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

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

What went into building it

Training it took roughly 1 × 10¹⁷ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.

Answers

AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) — common questions

01

When was AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) released?

AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) was published in August 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.

02

What is AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) used for?

AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) works in Language, and is recorded as handling language modeling/generation. 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 AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB)?

Around 1 × 10¹⁷ 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.

04

What GPU do I need to run AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB)?

None. AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (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.

05

Is AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) open source?

No. AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) has not had its weights published, so it exists only as a service controlled by its owner.

06

How many parameters does AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) have?

AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) has 24M 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.

07

Who created AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB)?

AWD-LSTM - 3-layer LSTM (tied) + continuous cache pointer (PTB) was published by Salesforce Research, based in United States of America, categorised as industry.
