Will GLM-4.5-Air run on my GPU?

106B parameters (mixture of experts, 12B active per token, but every expert must sit in memory), 131,072-token context, MIT. At Q4_K_M the weights come to about 59.2 GiB; add 1.5 GiB for the runtime and you need roughly 60.7 GiB of VRAM before context.

Headroom is what remains for the KV cache after weights and the 1.5 GiB reserve. How far it stretches depends on the architecture: grouped-query models are frugal, older dense models are not. If the table says tight, plan on a shorter context or a lower quant. Parameter count from the model's own card. The Buy column opens live Amazon listings; those links may earn us a commission.
