Quantizing LLM to GGML or GUFF Format: A Comprehensive Guide

[SiraHaruethaipree]

I would like to know about the detail, How to quantize LLM to GGML or GUFF format. Currently, I found few referent that describe about this e.g. https://github.com/rustformers/llm/blob/main/crates/ggml/README.md. In constant GPTQ have the referent paper that explain about the detail.
So have any website,blog suggest that describe about technique quantize GGML format.
Thank you for your help. :)
