Author here. For additional context, please read https://github.com/ggerganov/llama.cpp/discussions/638#discu... The loading time performance has been a huge win for usability, and folks have been having the most wonderful reactions after using this change. But we don't have a compelling enough theory yet to explain the RAM usage miracle. So please don't get too excited just yet! Yes things are getting more awesome, but like all things in science a small amount of healthy skepticism is warranted.

Great work. Is the new file format described anywhere? Skimming the issue comments I have a vague sense that r/o matter was colocated somewhere for zero copy mmap or is there more to it?

That's something I'm working on presently.
