Segatron -XL base, M=150 + HCP
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.

Table 1 reports WikiText results, Table 2 arxiv. WikiText experiments use the larger model of the two.
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
About this model
Segatron -XL base, M=150 + HCP was published by Microsoft Research,University of Waterloo, in United States of America, in March 2022. The organisation is categorised as industry,Academia.
It works in Language, and is recorded as doing language modeling.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
What went into building it
The training run consumed about 1.7 × 10¹⁸ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.
Around 103,000,000 tokens went into training it.
Answers
Segatron -XL base, M=150 + HCP — common questions
What GPU do I need to run Segatron -XL base, M=150 + HCP?
None. Segatron -XL base, M=150 + HCP 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 Segatron -XL base, M=150 + HCP open source?
No. Segatron -XL base, M=150 + HCP has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Segatron -XL base, M=150 + HCP have?
Segatron -XL base, M=150 + HCP has 151M parameters. Table 1 reports WikiText results, Table 2 arxiv. WikiText experiments use the larger model of the two. 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 Segatron -XL base, M=150 + HCP?
Segatron -XL base, M=150 + HCP was published by Microsoft Research,University of Waterloo, based in United States of America, categorised as industry,Academia.
When was Segatron -XL base, M=150 + HCP released?
Segatron -XL base, M=150 + HCP was published in March 2022. 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 Segatron -XL base, M=150 + HCP used for?
Segatron -XL base, M=150 + HCP works in Language, and is recorded as handling language modeling. These are the areas it was designed around; they describe intent rather than a hard boundary.
How much compute was used to train Segatron -XL base, M=150 + HCP?
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.
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.
