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.

from Table 3 RNMT+
"We train our models on the standard WMT’14 En→Fr and En→De datasets that comprise 36.3M and 4.5M sentence pairs, respectively" "For RNMT+, we use sentence-level cross entropy loss."
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.

- Hardware,Operation counting
32 * 9.3 TFLOPS * (120 * 3600) * 0.3 = 3.86e19 (number of gpus) * (peak flops) * (seconds) * (assumed utilization rate) "All models were trained with synchronous training. RNMT+ and ConvS2S were trained with 32 NVIDIA P100 GPUs", training time is 120h from Table 1. Alternatively, typical inference is 2.81e10 FLOP, there are 36.3M examples in the dataset, and they train for 8.5 epochs: 2.81e10 * 36.3M * 8.5 = 8.7e18 Geometric mean: sqrt(3.86e19 * 8.7e18) = 1.83e19

What the numbers mean
About this model
RNMT+ was published by Google AI, in United States of America, in April 2018. It comes out of industry.
It works in Language, and is recorded as doing translation.
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 1.8 × 10¹⁹ FLOP of computation, on NVIDIA P100 — a measure of what producing the model cost, not of how fast it answers.
Answers
RNMT+ — common questions
What GPU do I need to run RNMT+?
None. RNMT+ 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 RNMT+ open source?
No. RNMT+ has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does RNMT+ have?
RNMT+ has 378.9M parameters. from Table 3 RNMT+. 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.
Who created RNMT+?
RNMT+ was published by Google AI, based in United States of America, categorised as industry.
When was RNMT+ released?
RNMT+ was published in April 2018. 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 RNMT+ used for?
RNMT+ works in Language, and is recorded as handling translation. These are the areas it was designed around; they describe intent rather than a hard boundary.
How much compute was used to train RNMT+?
Around 1.8 × 10¹⁹ FLOP, on NVIDIA P100. 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.
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.
