DLRM-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.

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 United States of America, in July 2020. It comes out of industry.
It works in Recommendation, and is recorded as doing 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 describes the cost of creating it and has no bearing on how quickly it generates text.
Answers
DLRM-2021 — common questions
What GPU do I need to run DLRM-2021?
None. DLRM-2021 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 DLRM-2021 open source?
No. DLRM-2021 has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does DLRM-2021 have?
DLRM-2021 has 1T parameters. 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.
Who created DLRM-2021?
DLRM-2021 was published by Meta AI, based in United States of America, categorised as industry.
When was DLRM-2021 released?
DLRM-2021 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.
What is DLRM-2021 used for?
DLRM-2021 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.
How much compute was used to train DLRM-2021?
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.
