Nemotron-3-Nano-Omni-30B-A3B-Reasoning - TurboQuant MLX 3-bit

MLX 3-bit quantization of the text tower of Nemotron-3-Nano-Omni-30B-A3B-Reasoning (nvidia/Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16) with TurboQuant weight method. Apple Silicon native via mlx-lm.

This variant covers the LLM backbone only. Vision (CRADIO v4-H) + audio (Parakeet-TDT-0.6B-v2) encoders are NOT included — MLX-VLM Nemotron-Omni model class is pending upstream support (no PR observed as of 2026-05-04). For multimodal inference, use the GGUF variants with llama-mtmd-cli instead.

For the matched-KV stack — TurboQuant weights + TurboQuant KV-cache modifier — see majentik/Nemotron-3-Nano-Omni-30B-A3B-Reasoning-TurboQuant-MLX-3bit-TQ-KV. For the runtime KV-cache modifier itself, see majentik/Nemotron-3-Nano-Omni-30B-A3B-Reasoning-TurboQuant.

Modality matrix

Modality	Encoder	Quantization in this variant
Text	LLM backbone (Mamba-2 + Transformer hybrid Sparse MoE)	per the variant suffix
Image	CRADIO v4-H	BF16 (kept full-precision in every non-GGUF variant; GGUF uses mmproj-F16 split file)
Audio	Parakeet-TDT-0.6B-v2	BF16 (same rationale)
Video	Parakeet-TDT-0.6B-v2 + frame sampler	BF16 (≤ 2 min, 256 frames @ 2 FPS)

NVIDIA's official FP8 / NVFP4 recipe keeps both encoders + the cross-modal MLP projectors in BF16 to preserve multimodal accuracy. We follow that convention in every quantized variant we ship.

Runtime quirks

MLX-LM (text-only)

This variant covers the LLM backbone only. Vision + audio encoders are NOT included — MLX-VLM Nemotron-Omni model class is pending upstream support (no PR observed as of 2026-05-04).

Use the mlx_lm.generate API; enable_thinking is a runtime flag (see below).

Reasoning mode

enable_thinking defaults to True. To disable extended reasoning (e.g., for latency-sensitive cases), pass enable_thinking=False to the chat template / generate call. No separate "no-think" variant card exists — this is a runtime flag, not a model variant.
