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.

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.

What the numbers mean

Where it came from

DLRM-2021 was published by Meta AI, in the country recorded as United States of America, during July 2020. It comes out of an organisation categorised as industry.

It works in the domain of Recommendation, and is recorded as performing the task of recommender system.

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

How it was trained

The training run consumed about 3 × 10²⁰ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.

Answers

DLRM-2021 — common questions

01

DLRM-2021— what GPU do I need to run it?

None. This 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.

02

DLRM-2021— is it open source?

No. Its weights have not been published, so it exists only as a service controlled by its owner.

03

DLRM-2021— how many parameters does it have?

It has a parameter count of 1T. Figure 1 https://arxiv.org/abs/2104.05158. 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.

04

DLRM-2021— who created it?

It was published by Meta AI, based in United States of America, an organisation categorised as industry.

05

DLRM-2021— when was it released?

It was published in July 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.

06

DLRM-2021— what is it used for?

It works in the domain of Recommendation, and is recorded as handling the task of recommender system. These are the areas it was designed around; they describe intent rather than a hard boundary.

07

DLRM-2021— how much compute was used to train it?

Training consumed around 3 × 10²⁰ FLOP. 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.
