My limited understanding is that it would be a local model that exists only to determine a limited set of local information necessary to answer the user's request. This request and information would then be shared with the third party. Third parties would otherwise not have access into the local semantic model based on user personal data.
Does apple's own siri need to pass requests through their gatekeeper AI? I bet it doesn't. Personally, I'm generally happy with any answer apple comes up with so long as they're bound by the same set of restrictions as 3rd party companies. I feel like that's the only way to make sure apple won't "accidentally" hobble their competitors. (Like they did with their ridiculous 50c per app install fee for 3rd party app stores).
I want Claude and OpenAI to be able to compete with Siri on an equal footing. Just like Apple maps has to compete with google maps. Competition pushes companies to make better products.
Hm, I didn’t even consider that it could be an “agent” in the AI sense. I assumed this meant a service that runs on the device and interposes on requests to access privileged resources and enforces permissions checks on them. That is, the classical sense of the word agent in computing. Perhaps you’re right; in any case I don’t think there is really enough detail here to go off of.
