What GPU do I need to run zai-org/GLM-4.5-Air-FP8?
110.5B parameters, published in F8_E4M3. View on Hugging Face
GLM-4.5-Air-FP8 is published by zai-org on Hugging Face, with 113,796 downloads and 82 likes to date. It's a Glm4MoeForCausalLM model built for text-generation, published natively in F8_E4M3.
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.
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 caveat: 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-FP8 at its published (F8_E4M3) precision: 8× RTX 5060 Ti on simplepod, at $0.100/hr per GPU ($0.800/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
