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) |
|---|---|---|---|---|---|
| FP8 (native) | 25.9 GB | 31.0 GB | RTX 4080 Super | 1 | $0.338/hr |
| cheaper alt. | RTX 5060 Ti | 2 | $0.220/hr | ||
| INT4 (quantized) | 12.9 GB | 15.5 GB | RTX 5060 Ti | 1 | $0.110/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 Qwen3.8-27B-FP8 at its published (F8_E4M3) precision: 1× RTX 4080 Super, at $0.338/hr per GPU ($0.338/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Qwen3.8-27B-FP8: common questions
Does Qwen3.8-27B-FP8 fit on a 32 GB GPU?
Yes. At FP8 (native) it needs 31.0 GB of VRAM, so a 32 GB card holds it with 1.0 GB to spare. A 24 GB card is not enough for it at FP8 (native).
Is Qwen3.8-27B-FP8 already quantized?
Yes. It is published in FP8, one byte per parameter, so the 31.0 GB figure is already a quantized footprint rather than a full-precision one. Only INT4 goes below it, at 15.5 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.
What is the least VRAM Qwen3.8-27B-FP8 can run in?
15.5 GB, at INT4 (quantized), which fits a 16 GB card, against 31.0 GB at FP8 (native). That row assumes an INT4 checkpoint has actually been published for this model, so check its Hugging Face page before planning around it.
Does quantizing Qwen3.8-27B-FP8 lower the GPU bill?
Yes. At FP8 (native) the cheapest live fit is one RTX 4080 Super at $0.338/hr. At INT4 (quantized) it drops to one RTX 5060 Ti at $0.110/hr, provided a quantized checkpoint exists for it.
How to run Qwen3.8-27B-FP8
Run Qwen3.8-27B-FP8 with vLLM
Generic example, not from the model's own docs: adjust flags (quantization, context length, parallelism) for your setup.

Aquanode has no one-click deploy template for Qwen3.8-27B-FP8; you install the inference engine yourself with the commands below. Aquanode sells GPU pods billed per second, not a hosted inference API.
- Launch a bare GPU pod sized to the requirement above (1× RTX 4080 Super or larger).
- Open a terminal on the pod, or save one of the commands above as a startup script so it runs automatically the first time the pod boots.
- Run the command and connect to the resulting endpoint.
