What hardware runs GLM 4.5 Air?

GLM 4.5 Air is a 110.47B-parameter mixture-of-experts model with 14.96B active parameters (mit license). The community's favorite big MoE: agentic coding chops and genuinely good prose in one 12B-active package.

All figures assume an f16 KV cache, a 0.6 GB display reserve on the GPU, and 64 GB of DDR5 system RAM for the offload tiers. Tune these in the calculator.

Quant guidance

Our floor for GLM 4.5 Air is Q3_K_M — below that, quality degrades faster than the VRAM savings are worth (large models tolerate low bpw better than small ones, which is why the floor is lower here). Prefer the highest quant that still lands "Fits on GPU" or “Expert offload” at your context length in the table above.
