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.

Amazon Nova Sonic— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
Amazon Nova Sonic— 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.
Amazon Nova Sonic— who created it?
It was published by Amazon, based in United States of America, an organisation categorised as industry.
Amazon Nova Sonic— when was it released?
It was published in April 2025.
Amazon Nova Sonic— what is it used for?
It works in the domain of Speech, and is recorded as handling the task of speech-to-text, Speech recognition (ASR), Speech synthesis, Speech-to-speech, Audio question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
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.
