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 | 3.8 GB | 4.5 GB | RTX 5060 Ti | 1 | $0.110/hr |
| FP8 (quantized) | 1.9 GB | 2.3 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 0.9 GB | 1.1 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 Qwen3-1.7B at its published (BF16) precision: 1× RTX 5060 Ti, at $0.110/hr per GPU ($0.110/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Qwen3-1.7B: common questions
How much VRAM does Qwen3-1.7B need?
4.5 GB at BF16, 2.3 GB at FP8 (quantized), 1.1 GB at INT4 (quantized). All of those sit under 6 GB, the smallest capacity this page reasons about, so VRAM is not what limits where this model runs. The 3.8 GB of weights plus inference overhead is the whole requirement.
How many copies of Qwen3-1.7B fit on one RTX 5060 Ti?
3, by VRAM alone. That card carries 16.0 GB and one copy needs 4.5 GB at BF16, on a live rate of $0.110/hr for the whole card. Throughput is not modelled here, so 3 copies is not 3 times the requests served.

Aquanode has no one-click deploy template for Qwen3-1.7B; 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 5060 Ti 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.
