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.

Task
Language modeling, Neural Architecture Search - NAS

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.

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 × 10¹⁶ FLOP

Training on PTB: 6 FLOP / token / parameter * 24000000 parameters * 929000 tokens * 150 epochs = 2.00664e+16 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
NVIDIA GeForce GTX 1080 Ti

Availability

Whether you can obtain the model and run it on your own hardware, which is what decides if any of the graphics-card figures on this page apply.

What the numbers mean

Where it came from

ENAS was published by Google Brain,Carnegie Mellon University (CMU),Stanford University, in United States of America, in February 2018. industry,Academia,Academia is the category the publisher falls under.

It works in Language, and is recorded as doing language modeling, Neural Architecture Search - NAS.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

What went into building it

Producing it required around 2 × 10¹⁶ FLOP of arithmetic, on NVIDIA GeForce GTX 1080 Ti, which is a statement about the training budget rather than about inference.

Around 929,000 tokens went into training it.

Answers

ENAS — common questions

01

When was ENAS released?

ENAS was published in February 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.

02

What is ENAS used for?

ENAS works in Language, and is recorded as handling language modeling, Neural Architecture Search - NAS. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

03

How much compute was used to train ENAS?

Around 2 × 10¹⁶ 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.

04

What GPU do I need to run ENAS?

None. ENAS 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.

05

Is ENAS open source?

No. ENAS has not had its weights published, so it exists only as a service controlled by its owner.

06

How many parameters does ENAS have?

ENAS has 24M parameters. 24M 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.

07

Who created ENAS?

ENAS was published by Google Brain,Carnegie Mellon University (CMU),Stanford University, based in United States of America, categorised as industry,Academia,Academia.

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.
