4GB "Gemini Nano" model GGUF anyone?

Hi everyone,

I saw an article saying Chrome silently downloads a ~4GB AI model (likely "Gemini Nano") to your computer for features like text summarization.

Two questions:

1. What is the exact name/version of this model?
2. Is there a GGUF file available for download so I can run it locally with llama.cpp?

I want to use it locally instead of letting Chrome run it in the background.

Thanks!
