13.5B parameters, published in BF16. View on Hugging Face
Set up Nemotron-Labs-Diffusion-14BNemotron-Labs-Diffusion-14B is published by nvidia on Hugging Face, with 12,540 downloads and 154 likes to date. It's a NemotronLabsDiffusionModel model built for text-generation, published natively in BF16.
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 | 25.2 GB | 30.2 GB | RTX 4080 Super | 1 | $0.338/hr |
| cheaper alt. | RTX 5060 Ti | 2 | $0.220/hr | ||
| FP8 (quantized) | 12.6 GB | 15.1 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 6.3 GB | 7.5 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 Nemotron-Labs-Diffusion-14B at its published (BF16) 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.
Nemotron-Labs-Diffusion-14B: common questions
Does Nemotron-Labs-Diffusion-14B fit on a 32 GB GPU?
Yes. At BF16 it needs 30.2 GB of VRAM, so a 32 GB card holds it with 1.8 GB to spare. A 24 GB card is not enough for it at BF16.
What is the least VRAM Nemotron-Labs-Diffusion-14B can run in?
7.5 GB, at INT4 (quantized), which fits an 8 GB card, against 30.2 GB at BF16. 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 Nemotron-Labs-Diffusion-14B lower the GPU bill?
Yes. At BF16 the cheapest live fit is one RTX 4080 Super at $0.338/hr. At FP8 (quantized) it drops to one RTX 5060 Ti at $0.110/hr, provided a quantized checkpoint exists for it.
