Apple unveils its first foldable iPhone and a sensor that signs every pixel to counter AI images
In his first keynote as head of Apple, on Wednesday 9 September, John Ternus presented the iPhone Duo, the brand's first foldable phone, alongside the iPhone 18 Pro and the Apple Watch Series 12 and Ultra 4 fitted with new health sensors.
The novelty that matters for AI is called Apple Reference Image: arriving with the iPhone 18 Pro, this feature uses the camera sensor to "sign every pixel" at the moment of capture, to certify that a shot was neither generated nor retouched by an AI. Apple stresses its on-device models (which run on the device, not in the cloud) in the name of privacy.
The watches, by contrast, introduce always-listening features, such as Siri Recap and Live Rewind, able to transcribe and summarise ambient conversations; Apple says it does not keep the raw audio, but the promise reopens questions of consent the moment a device can, in principle, always listen.
Two directions coexist at Apple that day: proving the authenticity of an image, and normalising objects that capture continuously.
