What the numbers mean

Background

Chirp was published by Google, in the country recorded as United States of America, during June 2023. 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 recognition (ASR), Speech-to-text.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

Chirp — common questions

01

Chirp— how many parameters does it have?

It has a parameter count of 2B. "On Google Vertex AI, you can access Chirp, a 2B-parameter speech model which achieved incredible accuracy improvements in speech recognition over several languages" (https://medium.com/google-cloud/getting-started-with-chirp-the-googles-universal-speech-model-usm-on-vertex-ai-f54edaf4da93). 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.

02

Chirp— who created it?

It was published by Google, based in United States of America, an organisation categorised as industry.

03

Chirp— when was it released?

It was published in June 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

04

Chirp— what is it used for?

It works in the domain of Speech, and is recorded as handling the task of speech recognition (ASR), Speech-to-text. These are the areas it was designed around; they describe intent rather than a hard boundary.

05

Chirp— 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.

06

Chirp— is it open source?

No. Its weights have not been published, so it exists only as a service controlled by its owner.

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.
