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.

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
2.7 × 10¹⁹ FLOP

6 FLOP / token / parameter * 450000000 parameters * 74000 tokens per batch * 286000 steps = 5.71428e+19 FLOP 125000000000000 [assumed bf16] * 98 GPU-hours * 3600 sec / hour * 0.3 [assumed utilization] = 1.323e+19 FLOP geometric mean: sqrt(5.71428e+19*1.323e+19) = 2.749544e+19

What the numbers mean

Background

T2R + Random Init was published by University of Washington,Microsoft,DeepMind,Allen Institute for AI, in the country recorded as United States of America, during March 2021. The category the publisher falls under is academia,Industry,Industry,Research collective.

It works in the domain of Language, and is recorded as performing the task of language modeling.

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

What went into building it

The training run consumed about 2.7 × 10¹⁹ FLOP, on hardware recorded as NVIDIA V100. That figure measures what producing the model cost, and has no bearing on how fast it answers.

The training set ran to roughly 103,000,000 tokens of text.

Answers

T2R + Random Init — common questions

01

T2R + Random Init— 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

T2R + Random Init— is it open source?

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

03

T2R + Random Init— how many parameters does it have?

It has a parameter count of 450M. 450M source: https://arxiv.org/pdf/2203.12644 table 3. 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

T2R + Random Init— who created it?

It was published by University of Washington,Microsoft,DeepMind,Allen Institute for AI, based in United States of America, an organisation categorised as academia,Industry,Industry,Research collective.

05

T2R + Random Init— when was it released?

It was published in March 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.

06

T2R + Random Init— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

07

T2R + Random Init— how much compute was used to train it?

Training consumed around 2.7 × 10¹⁹ FLOP, on hardware recorded as NVIDIA V100. 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.
