What GPU do I need to run zai-org/GLM-5.3?
753.3B parameters, published in F8_E4M3. View on Hugging Face
GLM-5.3 is published by zai-org on Hugging Face, with 94,403 downloads and 1,440 likes to date. It's a GlmMoeDsaForCausalLM 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.
Weight-to-VRAM math, the fit rules, and how live prices are normalized: full methodology.
