110.5B parameters, published in BF16. View on Hugging Face
Set up GLM-4.5-AirGLM-4.5-Air is published by unsloth on Hugging Face, with 106,386 downloads and 8 likes to date. It's a Glm4MoeForCausalLM model built for text-generation, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for KV-cache, activations, and fragmentation. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| BF16 | 205.8 GB | 246.9 GB | RTX A6000 | 6 | $2.18/hr |
| FP8 (quantized) | 102.9 GB | 123.5 GB | RTX 5060 Ti | 8 | $0.880/hr |
| INT4 (quantized) | 51.4 GB | 61.7 GB | A100 | 1 | $1.21/hr |
| cheaper alt. | RTX 5060 Ti | 4 | $0.440/hr |
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run GLM-4.5-Air at its published (BF16) precision: 6× RTX A6000, at $0.363/hr per GPU ($2.18/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
GLM-4.5-Air: common questions
Can GLM-4.5-Air run on a single GPU?
No. At BF16 it needs 246.9 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest capable card in the live feed is a 48.0 GB RTX A6000, and it takes 6 of them.
How many GPUs do I need to run GLM-4.5-Air?
6 at BF16. It needs 246.9 GB of VRAM and the cheapest capable live offer is a 48.0 GB RTX A6000, so 6 of them come to $2.18/hr in total.
Does quantizing GLM-4.5-Air lower the GPU bill?
Yes. At BF16 the cheapest live fit is 6 RTX A6000 cards at $2.18/hr. At FP8 (quantized) it drops to 8 RTX 5060 Ti cards at $0.880/hr, provided a quantized checkpoint exists for it.
