Mixture of linear models
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.

What it does
The problem areas the model was built for. A model can carry several of each.
- Domain
- Vision
- Task
- Image classification
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.
- Parameters
- 384K
- Training data
- 1,792,000 tokens
“In the example we describe, 7000 training images are sufficient to fit 384,000 parameters“
"7000 training images are sufficient"
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.
- Training compute
- 4.5 × 10¹¹ FLOP
- How it was established
- Hardware
0.3*12*60*60*35000000=453600000000=4.54e11 Assuming a utilization of 0.3 and interpreting "overnight" as 12 hours. “the training procedure is fast enough to do the fitting overnight on an R4400-based machine. “ R4400 has 35MFLOPS (“Compare this to the 200MHz R4400 which is rated at about 35MFLOPS”, http://www.sgidepot.co.uk/perf.html)
The training run
What it physically took to train: which chips, how many, for how long, and what that drew from the wall.
- Wall-clock time
- 12 hours
"the training procedure is fast enough to do the fitting overnight on an R4400-based machine."

What the numbers mean
Background
Mixture of linear models was published by its authors, in December 1994.
It works in Vision, and is recorded as doing image classification.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
How it was trained
Training it took roughly 4.5 × 10¹¹ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.
Around 1,792,000 tokens went into training it.
Its inclusion criterion is historical significance.
Answers
Mixture of linear models — common questions
When was Mixture of linear models released?
Mixture of linear models was published in December 1994. 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 Mixture of linear models used for?
Mixture of linear models works in Vision, and is recorded as handling image classification. 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.
How much compute was used to train Mixture of linear models?
Around 4.5 × 10¹¹ 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 Mixture of linear models?
None. Mixture of linear models 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 Mixture of linear models open source?
The licensing for Mixture of linear models 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 Mixture of linear models have?
Mixture of linear models has 384K parameters. “In the example we describe, 7000 training images are sufficient to fit 384,000 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.
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.
