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.

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

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

Background

Luminous-extended was published by Aleph Alpha, in Germany, in August 2022. industry is the category the publisher falls under.

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.

Training and provenance

Producing it required around 1 × 10²³ FLOP of arithmetic, on NVIDIA A100 SXM4 40 GB, which is a statement about the training budget rather than about inference.

The training set ran to roughly 460,000,000,000 tokens.

Answers

Luminous-extended — common questions

01

Is Luminous-extended open source?

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

02

How many parameters does Luminous-extended have?

Luminous-extended has 30B parameters. ~30B (~42B with multi-modality). 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 Luminous-extended?

Luminous-extended was published by Aleph Alpha, based in Germany, categorised as industry.

04

When was Luminous-extended released?

Luminous-extended was published in August 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.

05

What is Luminous-extended used for?

Luminous-extended works in Language, and is recorded as handling language modeling/generation. 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

How much compute was used to train Luminous-extended?

Around 1 × 10²³ FLOP, on NVIDIA A100 SXM4 40 GB. 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.

07

What GPU do I need to run Luminous-extended?

None. Luminous-extended 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.
