Apple have a long antagonist relationship with NVIDIA. If anything it is holding Apple back because they don’t want to go cap in hand to NVIDIA and say “please sir, can I have some more”.
We see this play out with the ChatGPT integration. Rather than hosting GPT-4o themselves, OpenAI are. Apple is providing NVIDIA powered AI models through a third party, somewhat undermining the privacy first argument.
Not really. They use ChatGPT as a last resort for a question that isn't related to the device or an Apple-related interaction. Ex: "Make a recipe out of the foods in this image" versus "how far away is my mom from the lunch spot she told me about". And in that instance they ask the user explicitly whether they want to use ChatGPT.
