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.

What the numbers mean

What this model is

SparseOPT-13B was published by Institute of Science and Technology Austria (ISTA), in Austria, in January 2023. academia is the category the publisher falls under.

It works in Language, and is recorded as doing language modeling/generation, Question answering.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

Answers

SparseOPT-13B — common questions

01

Is SparseOPT-13B open source?

No. SparseOPT-13B has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does SparseOPT-13B have?

SparseOPT-13B has 13B parameters. 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.

03

Who created SparseOPT-13B?

SparseOPT-13B was published by Institute of Science and Technology Austria (ISTA), based in Austria, categorised as academia.

04

When was SparseOPT-13B released?

SparseOPT-13B was published in January 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

What is SparseOPT-13B used for?

SparseOPT-13B works in Language, and is recorded as handling language modeling/generation, Question answering. 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.

06

What GPU do I need to run SparseOPT-13B?

None. SparseOPT-13B 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.

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.
