Local Transformer (WT103)

Closed weights Google Research March 2020

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.

Around 103,000,000 tokens went into training it.

Answers

Local Transformer (WT103) — common questions

01

Is Local Transformer (WT103) open source?

No. Local Transformer (WT103) has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does Local Transformer (WT103) have?

No parameter count has been published for Local Transformer (WT103), which is why no memory or speed figure appears on this page.

03

Who created Local Transformer (WT103)?

Local Transformer (WT103) was published by Google Research, based in United States of America, categorised as industry.

04

When was Local Transformer (WT103) released?

Local Transformer (WT103) was published in March 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.

05

What is Local Transformer (WT103) used for?

Local Transformer (WT103) works in Language, and is recorded as handling language modeling. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

What GPU do I need to run Local Transformer (WT103)?

None. Local Transformer (WT103) 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.
