Weight Decay
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.

Size
How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

"It was trained on 400 to 5000 random words from the data base of around 20.000 words,"
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
Weight Decay was published by its authors, in December 1991.
It works in Speech, and is recorded as doing speech synthesis.
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
Producing it required around 7.5 × 10¹⁰ FLOP of arithmetic, which is a statement about the training budget rather than about inference.
It was trained on about 25,000 tokens of text.
The reason it appears in this catalogue at all is highly cited,Historical significance.
Answers
Weight Decay — common questions
When was Weight Decay released?
Weight Decay was published in December 1991. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is Weight Decay used for?
Weight Decay works in Speech, and is recorded as handling speech synthesis. These are the areas it was designed around; they describe intent rather than a hard boundary.
How much compute was used to train Weight Decay?
Around 7.5 × 10¹⁰ 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.
What GPU do I need to run Weight Decay?
None. Weight Decay 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.
Is Weight Decay open source?
The licensing for Weight Decay was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
How many parameters does Weight Decay have?
Weight Decay has 8.4K parameters. 7*26*40+40+40*26+26=8386 "The network had 7 x 26 input units, 40 hidden units and 26 output units". 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.
