SRU++ Base
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.

What the numbers mean
About this model
SRU++ Base was published by ASAPP, in the country recorded as United States of America, during February 2021. The category the publisher falls under is industry.
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
Producing it required arithmetic totalling around 2.6 × 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.
Answers
SRU++ Base — common questions
SRU++ Base— how much compute was used to train it?
Training consumed around 2.6 × 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.
SRU++ Base— 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.
SRU++ Base— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
SRU++ Base— how many parameters does it have?
It has a parameter count of 148M. 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.
SRU++ Base— who created it?
It was published by ASAPP, based in United States of America, an organisation categorised as industry.
SRU++ Base— when was it released?
It was published in February 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.
SRU++ Base— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling. These are the areas it was designed around; they describe intent rather than a hard boundary.
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.
