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
What this model is
Luminous-base was published by Aleph Alpha, in Germany, in August 2022. It comes out of 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.
How it was trained
Producing it required around 3.2 × 10²² 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 402,000,000,000 tokens.
Answers
Luminous-base — common questions
Is Luminous-base open source?
No. Luminous-base has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Luminous-base have?
Luminous-base has 13B parameters. ~13B (~15B 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.
Who created Luminous-base?
Luminous-base was published by Aleph Alpha, based in Germany, categorised as industry.
When was Luminous-base released?
Luminous-base 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.
What is Luminous-base used for?
Luminous-base 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.
How much compute was used to train Luminous-base?
Around 3.2 × 10²² 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.
What GPU do I need to run Luminous-base?
None. Luminous-base 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.
