In today's WWDC presentation, there were a few small examples of Siri improvements, such as an ability to maintain context, e.g., 'Add her flight arrival time to my calendar,' wherein Siri knows who "her" refers to.
In my day-to-day experience with Siri, it's clear Siri doesn't have the kind of ability to understand language that LLMs provide. It still feels like clever son-of-Eliza hacks with stock phrases. If your utterance doesn't match with a pre-programmed stock phrase, it doesn't work. The other day I said something like "Play the song you played before the one I asked you to skip," and Siri didn't seem to know what I wanted. OTOH, GPT4o can easily handle statements like that.
Does anyone know to what extent Siri's underlying language models are being upgraded?
