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.

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.

"To examine the effect of recurrence depth we train RHNs with fixed total parameters (32 M)"
"Batch size was fixed to 20, sequence length for truncated backpropagation to 35, learning rate to 0.2, learning rate decay to 1.02 starting at 20 epochs, weight decay to 1e-7 and maximum gradient norm to 10."
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
- 3.6 × 10¹⁵ FLOP
- How it was established
- Operation counting
6 FLOP / parameter / token * 32000000 parameters * 929000 tokens * 20 epochs = 3.56736e+15 FLOP

What the numbers mean
About this model
VD-RHN was published by ETH Zurich,IDSIA, in the country recorded as Switzerland, during July 2016. 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.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
Training and provenance
Training it took a computation budget of roughly 3.6 × 10¹⁵ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.
Training consumed a corpus of around 929,000 tokens of text.
Answers
VD-RHN — common questions
VD-RHN— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
VD-RHN— how many parameters does it have?
It has a parameter count of 32M. "To examine the effect of recurrence depth we train RHNs with fixed total parameters (32 M)". 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.
VD-RHN— who created it?
It was published by ETH Zurich,IDSIA, based in Switzerland, an organisation categorised as academia,Academia.
VD-RHN— when was it released?
It was published in July 2016. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
VD-RHN— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling. 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.
VD-RHN— how much compute was used to train it?
Training consumed around 3.6 × 10¹⁵ 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.
VD-RHN— 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.
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.
