1-bit LLMs

Representing model weights in ~1.58 bits (ternary {-1,0,1}) so matrix multiplies collapse to additions, letting large models run on commodity CPUs with a fraction of the memory and bandwidth.

grounded in: latest-trends theme: community fixated on squeezing large LLMs onto old CPUs and efficient weight storage rather than renting GPUs (HN front page, 2026-07-16)
