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
1.4 × 10¹⁷ FLOP

What the numbers mean

Where it came from

ONLSTM-SYD was published by Westlake University,Institute for Advanced Study,McGill University,Mila - Quebec AI (originally Montreal Institute for Learning Algorithms),CIFAR AI Research,University of Montreal / Université de Montréal, in China, in May 2020. It comes out of academia,Academia,Academia,Academia,Research collective,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.

Training and provenance

Training it took roughly 1.4 × 10¹⁷ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.

Around 912,344 tokens went into training it.

Answers

ONLSTM-SYD — common questions

01

How many parameters does ONLSTM-SYD have?

ONLSTM-SYD has 25M parameters. 25M Table 1. 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.

02

Who created ONLSTM-SYD?

ONLSTM-SYD was published by Westlake University,Institute for Advanced Study,McGill University,Mila - Quebec AI (originally Montreal Institute for Learning Algorithms),CIFAR AI Research,University of Montreal / Université de Montréal, based in China, categorised as academia,Academia,Academia,Academia,Research collective,Academia.

03

When was ONLSTM-SYD released?

ONLSTM-SYD was published in May 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

04

What is ONLSTM-SYD used for?

ONLSTM-SYD works in Language, and is recorded as handling language modeling. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

05

How much compute was used to train ONLSTM-SYD?

Around 1.4 × 10¹⁷ 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.

06

What GPU do I need to run ONLSTM-SYD?

None. ONLSTM-SYD 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.

07

Is ONLSTM-SYD open source?

No. ONLSTM-SYD has not had its weights published, so it exists only as a service controlled by its owner.

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.
