are you telling me that this feature on the pixel 8 wont work in airplane mode or if I turn off wifi and cellular?
I'm sorry, you require a powerful GPU. You can't execute AI locally on a mobile device, max you can do is execute it online. At least for now. Have a look at https://alternativeto.net/software/stable-diffusion-web-ui/about/

I don't know, but I can tell you I need an M2 pro mac with 16Gb or RAM to be able to run basic models on my computer, and it is rather slow sometimes. I doubt that chip would be able to do much except probably some photo retouching or voice recognition. I don't think you can run a chatgpt equivalent there, or Stable Diffusion with full image generation.
have you seen the magic eraser feature? all done by "the phone"...
