Nemotron-4 15B
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
Where it came from
Nemotron-4 15B was published by NVIDIA, in United States of America, in February 2024. It comes out of industry.
It works in Language, and is recorded as doing language modeling/generation, Code generation, Question answering, Translation, Quantitative reasoning.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
How it was trained
Producing it required around 7.5 × 10²³ FLOP of arithmetic, on NVIDIA H100 SXM5 80GB, which is a statement about the training budget rather than about inference.
Answers
Nemotron-4 15B — common questions
What is Nemotron-4 15B used for?
Nemotron-4 15B works in Language, and is recorded as handling language modeling/generation, Code generation, Question answering, Translation, Quantitative reasoning. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
How much compute was used to train Nemotron-4 15B?
Around 7.5 × 10²³ FLOP, on NVIDIA H100 SXM5 80GB. 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 Nemotron-4 15B?
None. Nemotron-4 15B 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 Nemotron-4 15B open source?
No. Nemotron-4 15B has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Nemotron-4 15B have?
Nemotron-4 15B has 15B parameters. 15b. 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 Nemotron-4 15B?
Nemotron-4 15B was published by NVIDIA, based in United States of America, categorised as industry.
When was Nemotron-4 15B released?
Nemotron-4 15B was published in February 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
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.
