Apple's Neural Engine debuts (2017)
Apple's A11 Bionic chip in the iPhone 8 and iPhone X added a Neural Engine, dedicated hardware for AI tasks like face recognition. It ran those jobs on the phone rather than in the cloud.
Face ID and photo features worked instantly and offline. Rivals rushed to add similar AI blocks to their chips.
On-device AI hardware became standard in flagship phones, setting the stage for today's on-device language models.
Google's Tensor G6 extends that same idea, running a full Gemini AI model locally instead of a single narrow task.
