NVIDIA-Nemotron-3-Super-120B-A12B-BF16-AutoRound-W4A16-draft

Draft AutoRound quantization of a Nemotron Super checkpoint.

Base model: nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-BF16

Draft status

This is a draft research release. It is published for inspection, reproducibility, and early runtime validation. It should not be treated as a final benchmarked production checkpoint.

How this was produced

We quantized the checkpoint with Intel AutoRound using the W4A16 scheme on the remote 8x RTX 3090 host. This lane is optimized for overnight completion and resumability rather than final accuracy tuning.

Settings used

• source checkpoint: /mnt/llm_models/NVIDIA-Nemotron-3-Super-120B-A12B-BF16
• source type: original base model
• quantizer: intel/auto-round 0.10.2
• scheme: W4A16
• format: auto_round
• calibration dataset: NeelNanda/pile-10k
• device_map: auto
• nsamples: 128
• iters: 50
• seqlen: 1024
• batch_size: 2
• nblocks: 1
• low_gpu_mem_usage: True
• output dir: /home/ser/nemotron-super/autoround_w4a16/original

Notes

• upstream provenance is preserved through the base model link above
• this repo is intentionally marked draft while quantization/runtime validation is still in progress
• donation link added per maintainer request
