LightOn Mini
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.

"Boasting an impressive 40 billion parameters, Mini is a formidable addition to the growing array of language models available in the market today."
"The amount of data in Mini corpus is 1 trillion tokens. We mainly used data from the public web to pre-train our model, with strong filtering, toxicity reduction, and deduplication to ensure that only high-quality data is retained." assuming 0.75 words per token - 750000000000.0 words
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
LightOn Mini was published by LightOn, in France, in March 2023. It comes out of industry.
It works in Language, and is recorded as doing language modeling/generation, Chat.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
How it was trained
Training it took roughly 2.4 × 10²³ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.
It was trained on about 1,000,000,000,000 tokens of text.
Answers
LightOn Mini — common questions
How much compute was used to train LightOn Mini?
Around 2.4 × 10²³ 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.
What GPU do I need to run LightOn Mini?
None. LightOn Mini 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.
Is LightOn Mini open source?
No. LightOn Mini has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does LightOn Mini have?
LightOn Mini has 40B parameters. "Boasting an impressive 40 billion parameters, Mini is a formidable addition to the growing array of language models available in the market today.". 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 LightOn Mini?
LightOn Mini was published by LightOn, based in France, categorised as industry.
When was LightOn Mini released?
LightOn Mini was published in March 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.
What is LightOn Mini used for?
LightOn Mini works in Language, and is recorded as handling language modeling/generation, Chat. 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.
The other direction
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.
