10 LSTMS + KN-5 (OPTIMAL WEIGHTS)
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.

"The experiments are performed on the 1B Word Benchmark data set introduced by (Chelba et al., 2013), which is a publicly available benchmark for measuring progress of statistical language modeling. The data set contains about 0.8B words with a vocabulary of 793471 words, including sentence boundary markers."
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
10 LSTMS + KN-5 (OPTIMAL WEIGHTS) was published by Google Brain, in United States of America, in February 2016. The organisation is categorised as industry.
It works in Language, and is recorded as doing language modeling.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
How it was trained
Training it took roughly 8.8 × 10¹⁹ FLOP of computation, on NVIDIA Tesla K40s — a measure of what producing the model cost, not of how fast it answers.
Answers
10 LSTMS + KN-5 (OPTIMAL WEIGHTS) — common questions
How much compute was used to train 10 LSTMS + KN-5 (OPTIMAL WEIGHTS)?
Around 8.8 × 10¹⁹ FLOP, on NVIDIA Tesla K40s. 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 10 LSTMS + KN-5 (OPTIMAL WEIGHTS)?
None. 10 LSTMS + KN-5 (OPTIMAL WEIGHTS) 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 10 LSTMS + KN-5 (OPTIMAL WEIGHTS) open source?
The licensing for 10 LSTMS + KN-5 (OPTIMAL WEIGHTS) 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 10 LSTMS + KN-5 (OPTIMAL WEIGHTS) have?
10 LSTMS + KN-5 (OPTIMAL WEIGHTS) has 1B parameters. 1.04B (Table 1). 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 10 LSTMS + KN-5 (OPTIMAL WEIGHTS)?
10 LSTMS + KN-5 (OPTIMAL WEIGHTS) was published by Google Brain, based in United States of America, categorised as industry.
When was 10 LSTMS + KN-5 (OPTIMAL WEIGHTS) released?
10 LSTMS + KN-5 (OPTIMAL WEIGHTS) was published in February 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.
What is 10 LSTMS + KN-5 (OPTIMAL WEIGHTS) used for?
10 LSTMS + KN-5 (OPTIMAL WEIGHTS) works in Language, and is recorded as handling 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.
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.
