GLM-5.3-Flash-ABLITERATED-FP8 is published by dealignai on Hugging Face, with 676 downloads and 15 likes to date. It's a Glm5NextForConditionalGeneration 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.

PrecisionWeight sizeRequired VRAMCheapest live fitGPUs neededEst. $/hr (full fit)
FP8 (native)299.3 GB359.1 GBRTX 40908$3.53/hr
INT4 (quantized)149.6 GB179.6 GBRTX A50008$1.41/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-5.3-Flash-ABLITERATED-FP8 at its published (F8_E4M3) precision: 8× RTX 4090, at $0.441/hr per GPU ($3.53/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.

GLM-5.3-Flash-ABLITERATED-FP8: common questions

Can GLM-5.3-Flash-ABLITERATED-FP8 run on a single GPU?

No. At FP8 (native) it needs 359.1 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 4090, and it takes 8 of them.

Is GLM-5.3-Flash-ABLITERATED-FP8 already quantized?

Yes. It is published in FP8, one byte per parameter, so the 359.1 GB figure is already a quantized footprint rather than a full-precision one. Only INT4 goes below it, at 179.6 GB. A GPU without FP8 tensor cores cannot run it as published, which is why cards here are matched on precision support and not on VRAM alone.

How many GPUs do I need to run GLM-5.3-Flash-ABLITERATED-FP8?

8 at FP8 (native). It needs 359.1 GB of VRAM and the cheapest capable live offer is a 48.0 GB RTX 4090, so 8 of them come to $3.53/hr in total.

Does quantizing GLM-5.3-Flash-ABLITERATED-FP8 lower the GPU bill?

Yes. At FP8 (native) the cheapest live fit is 8 RTX 4090 cards at $3.53/hr. At INT4 (quantized) it drops to 8 RTX A5000 cards at $1.41/hr, provided a quantized checkpoint exists for it.
