Question 1

How much VRAM does NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 need?

Accepted Answer

NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 (560.5B) requires approximately 1252.8151273727417 GB of VRAM at full precision (FP16), 626.4 GB at 8-bit quantization (Q8), and 313.2 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16?

Accepted Answer

We currently have no compatible GPUs indexed for NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16. This may be because the model's VRAM requirements exceed available GPUs in our database, or VRAM data hasn't been computed yet.

Question 3

What is the cheapest GPU to run NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16?

Accepted Answer

We don't currently have cloud pricing data for GPUs compatible with NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16. Cloud pricing data is updated regularly — check back soon.

Question 4

Can NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 run on consumer hardware?

Accepted Answer

NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 requires approximately 1252.8151273727417 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 313.2 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 requires datacenter or cloud GPUs.

Question 5

What quantization options are available for NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16?

Accepted Answer

NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 supports the following quantization levels: FP16 (full precision): ~1252.8151273727417 GB, Q8 (8-bit): ~626.4 GB, Q6 (6-bit): ~469.8 GB, Q4 (4-bit): ~313.2 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression. As a Mixture of Experts (MoE) model with 512 experts (22 active), NVIDIA-Nemotron-3-Ultra-550B-A55B-BF16 has a larger total weight size but only activates a subset of parameters per token, which can affect effective memory usage during inference.
