What the numbers mean

Where it came from

Luminous Sparse was published by Aleph Alpha,Graphcore, in Germany, in November 2022. The organisation is categorised as industry,Industry.

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

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

Luminous Sparse — common questions

01

When was Luminous Sparse released?

Luminous Sparse was published in November 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.

02

What is Luminous Sparse used for?

Luminous Sparse works in Language, and is recorded as handling language modeling/generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

03

What GPU do I need to run Luminous Sparse?

None. Luminous Sparse 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.

04

Is Luminous Sparse open source?

No. Luminous Sparse has not had its weights published, so it exists only as a service controlled by its owner.

05

How many parameters does Luminous Sparse have?

Luminous Sparse has 2.6B 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.

06

Who created Luminous Sparse?

Luminous Sparse was published by Aleph Alpha,Graphcore, based in Germany, categorised as industry,Industry.
