NAS+ESS (156M)
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 batch size was 128 and the number of hidden units was 300"
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
- 2.9 × 10¹⁸ FLOP
- How it was established
- Operation counting
6 FLOP / token / parameter * 156 * 10^6 parameters * 103000000 tokens * 30 epochs = 2.89224e+18 FLOP
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

What the numbers mean
What this model is
NAS+ESS (156M) was published by Northeastern University (China),Chinese Academy of Sciences,NiuTrans Research,Kingsoft, in China, in May 2020. The organisation is categorised as academia,Academia,Industry.
It works in Language, and is recorded as doing neural Architecture Search - NAS, Language modeling.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Training and provenance
Producing it required around 2.9 × 10¹⁸ FLOP of arithmetic, on NVIDIA GeForce GTX 1080 Ti, which is a statement about the training budget rather than about inference.
The training set ran to roughly 103,000,000 tokens.
Answers
NAS+ESS (156M) — common questions
What GPU do I need to run NAS+ESS (156M)?
None. NAS+ESS (156M) 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 NAS+ESS (156M) open source?
No. NAS+ESS (156M) has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does NAS+ESS (156M) have?
NAS+ESS (156M) has 156M parameters. 156M (Table 2). 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 NAS+ESS (156M)?
NAS+ESS (156M) was published by Northeastern University (China),Chinese Academy of Sciences,NiuTrans Research,Kingsoft, based in China, categorised as academia,Academia,Industry.
When was NAS+ESS (156M) released?
NAS+ESS (156M) was published in May 2020. 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 NAS+ESS (156M) used for?
NAS+ESS (156M) works in Language, and is recorded as handling neural Architecture Search - NAS, Language modeling. These are the areas it was designed around; they describe intent rather than a hard boundary.
How much compute was used to train NAS+ESS (156M)?
Around 2.9 × 10¹⁸ FLOP, on NVIDIA GeForce GTX 1080 Ti. 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.
