OCTAVE 3B
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
What this model is
OCTAVE 3B was published by Hume, in the country recorded as United States of America, during December 2024. It comes out of an organisation categorised as industry.
It works in the domain of Speech, and is recorded as performing the task of speech synthesis, Text-to-speech (TTS).
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Answers
OCTAVE 3B — common questions
OCTAVE 3B— who created it?
It was published by Hume, based in United States of America, an organisation categorised as industry.
OCTAVE 3B— when was it released?
It was published in December 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.
OCTAVE 3B— what is it used for?
It works in the domain of Speech, and is recorded as handling the task of speech synthesis, Text-to-speech (TTS). Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
OCTAVE 3B— what GPU do I need to run it?
None. This 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.
OCTAVE 3B— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
OCTAVE 3B— how many parameters does it have?
It has a parameter count of 3B. 3B. 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.
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.
