KN-LM

Closed weights Google 21B parameters June 2007

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.

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

Where it came from

KN-LM was published by Google, in United States of America, in June 2007. It comes out of industry.

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.

Training and provenance

The training run consumed about 7.7 × 10¹⁷ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Around 31,000,000,000 tokens went into training it.

It is tracked in the underlying dataset for one reason in particular: training cost,Highly cited.

Answers

KN-LM — common questions

01

Who created KN-LM?

KN-LM was published by Google, based in United States of America, categorised as industry.

02

When was KN-LM released?

KN-LM was published in June 2007. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

03

What is KN-LM used for?

KN-LM 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.

04

How much compute was used to train KN-LM?

Around 7.7 × 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.

05

What GPU do I need to run KN-LM?

None. KN-LM 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.

06

Is KN-LM open source?

The licensing for KN-LM was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

07

How many parameters does KN-LM have?

KN-LM has 21B parameters. Table 2. 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.

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.
