Gemini nano not available in Chrome

I have set the required flags as enabled in Chrome Flags. But I do not see Optimization Guide On Device Model in Chrome components or the model in on device internals.
This is my version:
Chrome Beta: 142.0.7444.53 (Official Build) beta (64-bit) (cohort: Beta)
Chrome Canary: 143.0.7495.0 (Official Build) canary (64-bit) (cohort: Clang-64)

I've signed up for the EPP

    Does https://developer.chrome.com/docs/ai/prompt-api#hardware-requirements help?

    Hi everyone
    Please note, I’ve followed all the setup steps from the discussion here (including enabling the required Chrome flags and using chrome version 143.0.7499.4 (Official Build) canary (64-bit) (cohort: Clang-64) ), but Gemini Nano is still not available.
    If it is possible can we have a quick session to go through the setup together? Any help or suggestions would be appreciated.

    What does the Model Status tab say in chrome://on-device-internals/?

    The model is showing as ready, however I have been trying all kind of troubleshoot the built in AI is not reachable (All the flags are appearing and I set them correctly even on the components I was able to download all necessary). Foundational Model

    This looks good to me. See https://developer.chrome.com/docs/ai/prompt-api#use_the_prompt_api for how to use Built-in AI APIs. Let me know if that helps

    Thank you François Beaufort, after some troubleshoot and restart I am able to get the APIs working
