Microsoft open sourced an inference framework that runs a 100B parameter LLM on a single CPU.It's called BitNet. And it does what was supposed to be impossible.No GPU. No cloud. No $10K hardware setup. Just your laptop running a 100-billion parameter model at human reading speed.Here's how it works:Every other LLM stores weights in 32-bit or 16-bit floats.BitNet uses 1.58 bits.Weights are ternary just -1, 0, or +1. That's it. No floats. No expensive matrix math. Pure integer operations your CPU
