T2R + Random Init
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.

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.

"We train the model with a batch size of about 74K tokens with a total of 286K steps" 74000*286000 / 103000000 = 205.48 epochs
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

- How it was established
- Operation counting,Hardware
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 United States of America, in March 2021. academia,Industry,Industry,Research collective is the category the publisher falls under.
It works in Language, and is recorded as doing 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 NVIDIA V100. That figure describes the cost of creating it and has no bearing on how quickly it generates text.
The training set ran to roughly 103,000,000 tokens.
Answers
T2R + Random Init — common questions
What GPU do I need to run T2R + Random Init?
None. T2R + Random Init 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 T2R + Random Init open source?
No. T2R + Random Init has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does T2R + Random Init have?
T2R + Random Init has 450M parameters. 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.
Who created T2R + Random Init?
T2R + Random Init was published by University of Washington,Microsoft,DeepMind,Allen Institute for AI, based in United States of America, categorised as academia,Industry,Industry,Research collective.
When was T2R + Random Init released?
T2R + Random Init 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.
What is T2R + Random Init used for?
T2R + Random Init works in Language, and is recorded as handling 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.
How much compute was used to train T2R + Random Init?
Around 2.7 × 10¹⁹ FLOP, on 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.
