Since then a number of JPEG replacements have come and gone – including JPEG 2000 – but now Google reckons that it can improve JPEG with Jpegli, a new encoder and decoder library that promises ...

Then, the brain encoder learns to align the MEG signals to those image embeddings. Finally, the image decoder creates a plausible image based on those brain representations.

Such as the fact that it compressed images around 35% more than traditional JPEG codecs while preserving their visual quality. That alone is a huge win for online bandwidth.
