Chirp
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
Background
Chirp was published by Google, in United States of America, in June 2023. It comes out of industry.
It works in Speech, and is recorded as doing 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
How many parameters does Chirp have?
Chirp has 2B parameters. "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.
Who created Chirp?
Chirp was published by Google, based in United States of America, categorised as industry.
When was Chirp released?
Chirp 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.
What is Chirp used for?
Chirp works in Speech, and is recorded as handling speech recognition (ASR), Speech-to-text. These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run Chirp?
None. Chirp 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.
Is Chirp open source?
No. Chirp has not had its weights published, so it exists only as a service controlled by its owner.
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.
