  • PICO is the first practical learned image codec optimized for the human visual system.
  • It achieved 2.3–3× bitrate savings over AV1, AV2, VVC, ECM, and JPEG-AI, and 20–40% savings over other learned codecs.
  • On an iPhone 17 Pro Max, it encodes 12MP images in 230ms and decodes in 150ms.
  • PICO includes cross-platform robustness guarantees, distinguishing it from most learned codecs.
