This seems really cool.
They said the models can scale to "private cloud compute" based on Apple Silicon which will be ensured by your device to run "publicly verifiable software" in order to guarantee no misuse of your data.
I wonder if their server-side code will be open-source? That'd be positively surprising. Curious to see how this evolves.
Anyway, overall looks really really cool. If it works as marketed, then it will be an easy "shut up and take my money". Siri seems to finally be becoming what it was meant to be (I wonder if they're piggy-backing on top of the Shortcuts Actions catalogue to have a wide array of possible actions right away), and the image and emoji generation features that integrate with Apple Photos and other parts of the system look _really_ cool.
It seems like it will require M1+ on Macs/iPads, or an iPhone 15 Pro.
