colibrì Tested: Running GLM-5.2 Without a GPU
Lopsided_Dot_4557 · reddit · 2026-07-15
The author conducted full tests using the pure C colibrì engine, attempting to run GLM-5.2 744B MoE on a single machine without a GPU.
Key Concepts
- The 744B MoE only activates a few experts per token.
- The engine keeps the dense components (around 10GB) in memory.
- The remaining expert weights are streamed on-demand from local disk/NVMe.
- The full int4 model is about 370GB, but it doesn't all reside in memory at once.
