I bumped into this on the Internet and, finding there was no mention of it here yet, thought it needed its own thread

"As of today, WaveOne image compression outperforms all commercial codecs and research approaches known to us on standard datasets where comparison is available. Furthermore, with access to a GPU our codec runs orders of magnitude faster than other recent ML-based solutions: for example, we typically encode or decode the Kodak dataset at over 100 images per second."
