Scouting report

Worked out how to run and fine-tune large models in 8-bit and then 4-bit without wrecking them, shipped it as bitsandbytes, and followed with QLoRA — which put fine-tuning a 65B model on a single consumer GPU. His hardware guides are the reference for anyone deciding what to buy.

Curator’s note

Turned "you need a datacentre" into "you need one good GPU".
