unsloth/nvidia-nemotron-3-ultra-550b-a55b-nvfp4

NVIDIA released the Nemotron-3-Ultra-550B-A55B-NVFP4 model, a 550-billion-parameter large language model with 55 billion active parameters using NVFP4 quantization, under the OpenMDW-1.1 license. The model, hosted externally on ModelScope and indexed by Hugging Bay, requires multi-GPU or high-RAM hardware and is pending safety and license review.
