In most ways this is good and inevitable: Siri is one of the world's most widely-used voice agents, and it would be good if it didn't suck. The idea that Apple would boost its capabilities with frontier models wasn't so much ... Continue reading The future of Siri, or: why private inference isn't private enough ->
