744B Model Runs Locally on a Laptop
WesEklund · x · 2026-07-11
Colibri runs GLM-5.2 744B MoE on a laptop using pure C with zero dependencies, requiring only 25GB of RAM according to the author.
The core ideas:
- Each token activates only about 40B parameters, allowing the dense part to stay in memory
- Expert parameters are streamed from disk on demand, not loaded all at once
- The entire implementation is roughly 2400 lines of C code, no GPU, BLAS, or Python needed at runtime
This demonstrates a more aggressive approach to running large MoEs locally on CPU.
