Qwen3.6-27B-A3B-Niwaki-2bit-GGUF

**GGUF builds of Qwen3.6-27B-A3B-Niwaki-2bit-mlx —

Qwen3.6-35B-A3B pruned to 19B total / 3.3B active parameters — for

llama.cpp and everything built on it.**

Niwaki (庭木): every routed expert individually width-pruned to the neurons

its own routed tokens actually use, reconstructed to compensate, then briefly distilled from the full model, and

stored at low precision. A paper with the full method is coming soon.

Files

| file | size | wt2 ppl (llama.cpp, 512-ctx) |

|---|---|---|

| Qwen3.6-27B-A3B-Niwaki-2bit-UD-Q3K.gguf (recommended) | 13.5 GB | 10.41 ±0.07 |

| Qwen3.6-27B-A3B-Niwaki-2bit-Q4_K_M.gguf | 17.8 GB | 10.51 ±0.07 |

Reference Qwen3.6-35B-A3B at Q8_0 measures 6.95 under the identical

protocol (llama-perplexity, WikiText-2 test, 512-token windows). These

llama.cpp numbers are not directly comparable to the MLX repo's 2048-window

benchmarks; the relative standings match across both.

Generation battery (measured on the canonical MLX weights; reference scores 0.89 / 0.78): bigram-diversity avg/min = 0.89 / 0.79 across an 8-prompt code/reasoning/chat/creative battery.

The recommended UD-Q3K build is quantized structure-aware (importance matrices calibrated on the same mixed web/code/chat/reasoning corpus as the model itself), mirroring the

artifact's native allocation: the always-active backbone (attention, shared

experts, embeddings) is kept at high precision (Q6_K) while the pruned routed

experts ride a compact carrier (q3_k, imatrix-guided). It matches or beats

uniform Q4_K_M quality at ~20% fewer bytes on this model family.
