Apple Uses AI to Rework Image Compression: Same Visual Quality at One-Third the File Size

苹果用AI重新发明了图像压缩：同样画质，文件只要三分之一

Apple’s team published PICO, a perceptual image codec that uses 57%-70% fewer bits than AV1, VVC, and JPEG AI at the same subjective visual quality, while encoding a 12MP photo in 230 ms and decoding it in 150 ms on an iPhone 17 Pro Max.

Why it matters: HKR-H/K/R all pass: Apple PICO has concrete 57%-70% bitrate savings and 230 ms on-device encoding data. It remains a research release, not a shipped platform feature, so it sits in the 78-84 band.
