Great work. Just Yesterday I thought about LLMzip and asked myself if this is something which could vastly improve HTML compression when done at Google scale and shipped with browsers. I haven't done any research though.
I mean neural compressors provide great compression, BUTT the issue is they are really slow like in my project it takes around 45 minutes for de compression of 100 mb so I doubt if it would be useful, also using a transformer in user's browser sounds like a heavy task.
