Set up NVIDIA-Nemo…a-550B-A55B-BF16NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 is published by nvidia on Hugging Face, with 287,095 downloads and 337 likes to date. It's a NemotronHForCausalLM 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.
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.
NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16: common questions
Can NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 run on a single GPU?
Not on a desktop card. At BF16 it needs 1252.9 GB of VRAM, more than a single 32 GB desktop card holds. No card currently listed on the marketplace both supports BF16 and has enough VRAM for it, so how many it would take is not something this page can answer today.
