Amid notable new merchandise just like the Apple Silicon Mac Professional and the Apple Imaginative and prescient Professional revealed at Monday’s WWDC 2023 keynote occasion, Apple presenters by no means as soon as talked about the time period “AI,” a notable omission on condition that its opponents like Microsoft and Google have been closely specializing in generative AI in the mean time. Nonetheless, AI was part of Apple’s presentation, simply by different names.
Whereas “AI” is a really ambiguous time period nowadays, surrounded by each astounding developments and excessive hype, Apple selected to keep away from that affiliation and as an alternative targeted on phrases like “machine studying” and “ML.” For instance, in the course of the iOS 17 demo, SVP of Software program Engineering Craig Federighi talked about enhancements to autocorrect and dictation:
Autocorrect is powered by on-device machine studying, and over time, we’ve continued to advance these fashions. The keyboard now leverages a transformer language mannequin, which is cutting-edge for phrase prediction, making autocorrect extra correct than ever. And with the facility of Apple Silicon, iPhone can run this mannequin each time you faucet a key.
Notably, Apple talked about the AI time period “transformer” in an Apple keynote. The corporate particularly talked a couple of “transformer language mannequin,” which suggests its AI mannequin makes use of the transformer structure that has been powering many latest generative AI improvements, such because the DALL-E picture generator and the ChatGPT chatbot.
A transformer mannequin (an idea first launched in 2017) is a kind of neural community structure utilized in pure language processing that employs a self-attention mechanism, permitting it to prioritize completely different phrases or components in a sequence. Its potential to course of inputs in parallel has led to important effectivity enhancements and powered breakthroughs in pure language processing (NLP) duties resembling translation, summarization, and question-answering.
Apparently, Apple’s new transformer mannequin in iOS 17 permits sentence-level autocorrections that may end both a phrase or a whole sentence if you press the area bar. It learns out of your writing type as effectively, which guides its strategies.

All this on-device AI processing is pretty simple for Apple due to a particular portion of Apple Silicon chips (and earlier Apple chips, beginning with the A11 in 2017) referred to as the Neural Engine, which is designed to speed up machine studying purposes. Apple additionally mentioned that dictation “will get a brand new transformer-based speech recognition mannequin that leverages the Neural Engine to make dictation much more correct.”

Through the keynote, Apple additionally talked about “machine studying” a number of different occasions: whereas describing a brand new iPad lock display characteristic (“When you choose a Dwell Photograph, we use a sophisticated machine studying mannequin to synthesize extra frames”); iPadOS PDF options (“Because of new machine studying fashions, iPadOS can establish the fields in a PDF so you need to use AutoFill to shortly fill them out with info like names, addresses, and emails out of your contacts.”); an AirPods Adaptive Audio characteristic (“With Personalised Quantity, we use machine studying to grasp your listening preferences over time”); and an Apple Watch widget characteristic referred to as Sensible Stack (“Sensible Stack makes use of machine studying to indicate you related info proper if you want it”).
Apple additionally debuted a brand new app referred to as Journal that enables private textual content and picture journaling (type of like an interactive diary), locked and encrypted in your iPhone. Apple mentioned that AI performs an element, nevertheless it didn’t use the time period “AI.”
“Utilizing on-device machine studying, your iPhone can create personalised strategies of moments to encourage your writing,” Apple mentioned. “Strategies shall be intelligently curated from info in your iPhone, like your pictures, location, music, exercises, and extra. And also you management what to incorporate if you allow Strategies and which of them to save lots of to your Journal.”
