where is the Optimization Guide On Device Model component?

[Connie Leung]

Hi,

Chrome uses the Gemini Nano based on gemini-3n.

I opened chrome://components and could not find "Optimization Guide On Device Model".

How do I know the version of the model that I am using?

Thanks,

Connie

chrome://on-device-internals/

in the Model Status tab

Model Name: v3Nano
Version: 2025.06.30.1229

Thank you.

The documents are outdated.

https://developer.chrome.com/docs/ai/prompt-api states to go to chrome://on-device-internals

https://developer.chrome.com/docs/ai/get-started#troubleshoot_localhost states to visit chrome://components and look for "Optimization Guide....".

My memory also says to find the model info on chrome://components.

Hey all,

You are correct, the previously available chrome://component info on the optimization guide on device model was removed. This is what it looked like. It's now all in chrome://on-device-internals. I get the docs updated.

Cheers,

Tom
