Transformer-XL DeFINE (141M)
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.
- Training compute
- 1.7 × 10¹⁸ FLOP
- How it was established
- Operation counting
6 FLOP / token / parameter * 141000000 parameters * 103000000 tokens * 20 epochs [assumption based on number of epochs for LSTMs] = 1.74276e+18 FLOP _______________ older estimation: 6.2 × 10^18 (no explantion how it was calculated)

What the numbers mean
Where it came from
Transformer-XL DeFINE (141M) was published by University of Washington,Allen Institute for AI, in United States of America, in November 2019. academia,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.
Training and provenance
Training it took roughly 1.7 × 10¹⁸ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.
The training set ran to roughly 103,000,000 tokens.
The reason it appears in this catalogue at all is sOTA improvement.
Answers
Transformer-XL DeFINE (141M) — common questions
How many parameters does Transformer-XL DeFINE (141M) have?
Transformer-XL DeFINE (141M) has 141M parameters. Table 2b. 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 Transformer-XL DeFINE (141M)?
Transformer-XL DeFINE (141M) was published by University of Washington,Allen Institute for AI, based in United States of America, categorised as academia,Research collective.
When was Transformer-XL DeFINE (141M) released?
Transformer-XL DeFINE (141M) was published in November 2019. 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 Transformer-XL DeFINE (141M) used for?
Transformer-XL DeFINE (141M) 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 Transformer-XL DeFINE (141M)?
Around 1.7 × 10¹⁸ 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.
What GPU do I need to run Transformer-XL DeFINE (141M)?
None. Transformer-XL DeFINE (141M) 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 Transformer-XL DeFINE (141M) open source?
No. Transformer-XL DeFINE (141M) has not had its weights published, so it exists only as a service controlled by its owner.
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.
