I'm on Chrome 147 too and disabled:

"optimization-guide-on-device-model"

- Enables optimization guide on device

"prompt-api-for-gemini-nano"

- Prompt API for Gemini Nano

- Prompt API for Gemini Nano with Multimodal Input

and deleted weights.bin and the 2025.x folder in "OptGuideOnDeviceModel"

Will report if Chrome 148 downloads the model again.
