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.

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.

It was trained on O(1k) hours of audio
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
Movie Gen Audio was published by Meta AI, in United States of America, in October 2024. The organisation is categorised as industry.
It works in Audio, and is recorded as doing audio generation.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
How it was trained
The training run consumed about 1.4 × 10²³ FLOP, on NVIDIA H100 SXM5 80GB. That figure describes the cost of creating it and has no bearing on how quickly it generates text.
Answers
Movie Gen Audio — common questions
What is Movie Gen Audio used for?
Movie Gen Audio works in Audio, and is recorded as handling audio 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.
How much compute was used to train Movie Gen Audio?
Around 1.4 × 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 Movie Gen Audio?
None. Movie Gen Audio 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 Movie Gen Audio open source?
No. Movie Gen Audio has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Movie Gen Audio have?
Movie Gen Audio has 13B parameters. 13B. 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 Movie Gen Audio?
Movie Gen Audio was published by Meta AI, based in United States of America, categorised as industry.
When was Movie Gen Audio released?
Movie Gen Audio 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.
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.
