Set up TurboWan2.1…V-1.3B-DiffusersTurboWan2.1-T2V-1.3B-Diffusers is published by IPostYellow on Hugging Face, with 55,434 downloads and 0 likes to date. It's a unlisted-architecture model built for text-to-video, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for activation memory and allocator fragmentation. Diffusion and video models carry no KV-cache. The real driver of extra memory is output resolution and frame count, which this flat overhead does not model. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| BF16 | 2.6 GB | 3.2 GB | RTX 3070 | 1 | $0.088/hr |
| FP8 (quantized) | 1.3 GB | 1.6 GB | RTX 4070 | 1 | $0.121/hr |
| INT4 (quantized) | 0.7 GB | 0.8 GB | RTX 3070 | 1 | $0.088/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 TurboWan2.1-T2V-1.3B-Diffusers at its published (BF16) precision: 1× RTX 3070, at $0.088/hr per GPU ($0.088/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
TurboWan2.1-T2V-1.3B-Diffusers: common questions
How much VRAM does TurboWan2.1-T2V-1.3B-Diffusers need?
3.2 GB at BF16, 1.6 GB at FP8 (quantized), 0.8 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 2.6 GB of weights plus inference overhead is the whole requirement.
How many copies of TurboWan2.1-T2V-1.3B-Diffusers fit on one RTX 3070?
2, by VRAM alone. That card carries 8.0 GB and one copy needs 3.2 GB at BF16, on a live rate of $0.088/hr for the whole card. Throughput is not modelled here, so 2 copies is not 2 times the requests served.
