Q: How fast is GLM-5.3-Flash (Ox Alpha) on the Apple M1?

~5.9–7.4 tok/s (active-expert estimate) on the Apple M1. computed roofline: 68.25 GB/s × 0.80–1.00 efficiency window / 9.2GB (Q4_K_M) — bands, never points. MoE: file is 164GB (that decides fit) but only ~18B of experts activate per token (~9.2GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
