Nemotron-3.5-Lightning-30B-A3B-MLX-6bit

MLX 6bit (affine, group size 64) quantized variant of nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16 for Apple silicon via mlx-lm.

Provenance

Source: nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16 @ revision d468880b6ad3c6e0d21377ce7242adaea4cc884d (OpenMDW v1.1 — see LICENSE in this repo).
Quantized with mlx_lm.convert (mlx-lm 0.31.3): affine, 6-bit, group size 64.

Smoke gate

Before upload this pack passed a deterministic coherence gate: greedy 48-token chat generation loaded through mlx_lm.load, judged for emptiness, repetition loops, multi-script gibberish, and special-token debris. Verdict: ok.

Usage

pip install mlx-lm
mlx_lm.generate --model majentik/Nemotron-3.5-Lightning-30B-A3B-MLX-6bit --prompt "Hello"
