DLRM-12T

Closed weights Meta AI,Carnegie Mellon University (CMU) 12T parameters April 2021

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.

What it does

The problem areas the model was built for. A model can carry several of each.

Domain
Recommendation
Task
Recommender system

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.

Parameters
12T

They instantiated a 12T-parameter model to show that their hardware setup can train it despite the huge memory requirements.

Training data
tokens

No training details provided.

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 A100

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

Background

DLRM-12T was published by Meta AI,Carnegie Mellon University (CMU), in United States of America, in April 2021. The organisation is categorised as industry,Academia.

It works in Recommendation, and is recorded as doing recommender system.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

Answers

DLRM-12T — common questions

01

Is DLRM-12T open source?

No. DLRM-12T has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does DLRM-12T have?

DLRM-12T has 12T parameters. They instantiated a 12T-parameter model to show that their hardware setup can train it despite the huge memory requirements. 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.

03

Who created DLRM-12T?

DLRM-12T was published by Meta AI,Carnegie Mellon University (CMU), based in United States of America, categorised as industry,Academia.

04

When was DLRM-12T released?

DLRM-12T was published in April 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

What is DLRM-12T used for?

DLRM-12T works in Recommendation, and is recorded as handling recommender system. These are the areas it was designed around; they describe intent rather than a hard boundary.

06

What GPU do I need to run DLRM-12T?

None. DLRM-12T 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.

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.
