Does one need to train an AI model on specific hardware, or can a model be trained in one place and then used somewhere else? Seems like Apple could just run their fine tuned model called Siri on each device. Seems to me like asking for training on Apple devices is missing the strategy. Unless of course, it's just for purely scientific $reasons like "why install Doom on the toaster?" vs doing it for a purpose.
It doesn’t require specific hardware; you can train a neural net with pencil and paper if you have enough time. Of course, some pieces of hardware are more efficient than others for this.
