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.

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

What this model is

Attend-Infer-Repeat was published by Google DeepMind, in United States of America, in August 2016. The organisation is categorised as industry.

It works in Vision, and is recorded as doing object recognition.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Training and provenance

Training it took roughly 6.4 × 10¹⁶ FLOP of computation, on NVIDIA Quadro K4000 — a measure of what producing the model cost, not of how fast it answers.

Answers

Attend-Infer-Repeat — common questions

01

How many parameters does Attend-Infer-Repeat have?

Attend-Infer-Repeat has 82.1M parameters. from appendix E: The convolutional neural network uses a 64×(5×5)-64×(5×5)-64×(5×5)-512 architecture. 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.

02

Who created Attend-Infer-Repeat?

Attend-Infer-Repeat was published by Google DeepMind, based in United States of America, categorised as industry.

03

When was Attend-Infer-Repeat released?

Attend-Infer-Repeat was published in August 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.

04

What is Attend-Infer-Repeat used for?

Attend-Infer-Repeat works in Vision, and is recorded as handling object recognition. These are the areas it was designed around; they describe intent rather than a hard boundary.

05

How much compute was used to train Attend-Infer-Repeat?

Around 6.4 × 10¹⁶ FLOP, on NVIDIA Quadro K4000. 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.

06

What GPU do I need to run Attend-Infer-Repeat?

None. Attend-Infer-Repeat 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.

07

Is Attend-Infer-Repeat open source?

The licensing for Attend-Infer-Repeat was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
