Linear Transformer (small)
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
- Language
- Task
- Language modeling, Translation
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
- 40M
- Training data
- 103,000,000 tokens
- Epochs
- 120
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
- 1.7 × 10¹⁸ FLOP
- How it was established
- Operation counting
"For the small and medium configurations, we use batch sizes of 96 and 56 sequences, respectively, and train for about 120 and 70 epochs." Training compute: 6*40000000*70*103000000=1.7304e+18
The training run
What it physically took to train: which chips, how many, for how long, and what that drew from the wall.
- Training hardware
- NVIDIA V100
- Chips used

- Power draw
- 1.2 kW

What the numbers mean
Where it came from
Linear Transformer (small) was published by IDSIA,SUPSI, in the country recorded as Switzerland, during February 2021. The publishing organisation is categorised as academia,Academia.
It works in the domain of Language, and is recorded as performing the task of language modeling, Translation.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Training and provenance
Training it took a computation budget of roughly 1.7 × 10¹⁸ FLOP, on hardware recorded as NVIDIA V100. That figure measures what producing the model cost, and has no bearing on how fast it answers.
The training set ran to roughly 103,000,000 tokens of text.
Answers
Linear Transformer (small) — common questions
Linear Transformer (small)— how much compute was used to train it?
Training consumed around 1.7 × 10¹⁸ FLOP, on hardware recorded as NVIDIA V100. 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.
Linear Transformer (small)— what GPU do I need to run it?
None. This 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.
Linear Transformer (small)— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
Linear Transformer (small)— how many parameters does it have?
It has a parameter count of 40M. 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.
Linear Transformer (small)— who created it?
It was published by IDSIA,SUPSI, based in Switzerland, an organisation categorised as academia,Academia.
Linear Transformer (small)— when was it released?
It was published in February 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
Linear Transformer (small)— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling, Translation. 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.
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.
