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.

What the numbers mean

About this model

AWD-FWM (PTB) was published by IDSIA,Microsoft Research, in Switzerland, in November 2020. The organisation is categorised as academia,Industry.

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

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

Answers

AWD-FWM (PTB) — common questions

01

What is AWD-FWM (PTB) used for?

AWD-FWM (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.

02

What GPU do I need to run AWD-FWM (PTB)?

None. AWD-FWM (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 AWD-FWM (PTB) open source?

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

04

How many parameters does AWD-FWM (PTB) have?

AWD-FWM (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.

05

Who created AWD-FWM (PTB)?

AWD-FWM (PTB) was published by IDSIA,Microsoft Research, based in Switzerland, categorised as academia,Industry.

06

When was AWD-FWM (PTB) released?

AWD-FWM (PTB) was published in November 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
