"We are still working to improve OCTAVE, and given its range of new capabilities, we are taking a cautious approach to releasing it. We’ve begun giving trusted partners early access to a limited version of OCTAVE so that the model can be evaluated for safety and effectiveness in various application settings. We plan to roll out broader availability in the coming months. "

What the numbers mean

Background

OCTAVE 8B was published by Hume, in United States of America, in December 2024. The organisation is categorised as industry.

It works in Speech, and is recorded as doing speech synthesis, Text-to-speech (TTS).

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Answers

OCTAVE 8B — common questions

01

Who created OCTAVE 8B?

OCTAVE 8B was published by Hume, based in United States of America, categorised as industry.

02

When was OCTAVE 8B released?

OCTAVE 8B 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.

03

What is OCTAVE 8B used for?

OCTAVE 8B works in Speech, and is recorded as handling speech synthesis, Text-to-speech (TTS). 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.

04

What GPU do I need to run OCTAVE 8B?

None. OCTAVE 8B 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.

05

Is OCTAVE 8B open source?

No. OCTAVE 8B has not had its weights published, so it exists only as a service controlled by its owner.

06

How many parameters does OCTAVE 8B have?

OCTAVE 8B has 8B parameters. 8B. 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.
