Chatterbox Multilingual
No estimate
No hardware requirements for this model
This model's weights are open, but no parameter count has been published for it. Every memory and speed figure starts from that number, so we would rather show nothing than a fabricated estimate.
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.

Answers
Chatterbox Multilingual — common questions
Chatterbox Multilingual— when was it released?
It was published in September 2025.
Chatterbox Multilingual— what is it used for?
It works in the domain of Speech, and is recorded as handling the task of text-to-speech (TTS), Speech synthesis. 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.
Chatterbox Multilingual— where can I download it?
Its weights are published on Hugging Face, under the organisation ResembleAI. We do not host model files — this site calculates what hardware is needed to run them.
Chatterbox Multilingual— what GPU do I need to run it?
We cannot say. It has open weights, but no parameter count has been published for it, and every memory and speed calculation starts from that number. We would rather show nothing than a fabricated estimate.
Chatterbox Multilingual— is it open source?
Its weights are published, so it can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.
Chatterbox Multilingual— how many parameters does it have?
No parameter count has been published for it, which is why no memory or speed figure appears on this page.
Chatterbox Multilingual— who created it?
It was published by Resemble AI, based in United States of America, an organisation categorised as industry.
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.
