Can I run GLM 4.5 Air (MoE) locally?

GLM 4.5 Air (MoE) has 110.47 billion parameters (Hugging Face). At the popular Q4_K_M quantization it needs roughly 71.7 GB of GPU memory ESTIMATE. It has been on Hugging Face since 2025-07-20. It's a mixture-of-experts model: all weights must fit in memory, but it generates faster than a dense model of the same size.
