Can the NVIDIA B200 run GLM-4.5-Air?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Q8 yes 211k 55.1-65.7 t/s ~0.3-0.3 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA B200 run GLM-4.5-Air?โ–ถ

Yes. At Q4 it generates ~98.4-117.3 tok/s and fits up to 353k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.5-0.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 353k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
