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.

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
NVLM-X 72B was published by NVIDIA, in United States of America, in October 2024. industry is the category the publisher falls under.
It works in Vision, Language, and is recorded as doing language modeling/generation, Vision-language generation, Question answering, Code generation, Translation, Quantitative reasoning.
Its starting point was Qwen2-72B,InternViT-6B — most models at this scale are adapted from an existing base rather than built from nothing.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Training and provenance
Training it took roughly 3 × 10²⁴ FLOP of computation, on NVIDIA H100 SXM5 80GB — a measure of what producing the model cost, not of how fast it answers.
The training set ran to roughly 45,875,200,000 tokens.
It is tracked in the underlying dataset for one reason in particular: training cost.
Answers
NVLM-X 72B — common questions
Is NVLM-X 72B open source?
No. NVLM-X 72B has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does NVLM-X 72B have?
NVLM-X 72B has 72B parameters. 72B. 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 NVLM-X 72B?
NVLM-X 72B was published by NVIDIA, based in United States of America, categorised as industry.
When was NVLM-X 72B released?
NVLM-X 72B was published in October 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.
What is NVLM-X 72B used for?
NVLM-X 72B works in Vision, Language, and is recorded as handling language modeling/generation, Vision-language generation, Question answering, Code generation, Translation, Quantitative reasoning. 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.
How much compute was used to train NVLM-X 72B?
Around 3 × 10²⁴ 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 NVLM-X 72B?
None. NVLM-X 72B 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.
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.
