	# Qwen3.6-27B-Omnimerge-v4-GGUF

	GGUF quantizations of [`ManniX-ITA/Qwen3.6-27B-Omnimerge-v4`](https://huggingface.co/ManniX-ITA/Qwen3.6-27B-Omnimerge-v4) — the MLP-passthrough variant that defends against the Qwen3.6 think-policy fragility we discovered. Source dtype is BF16; this repo provides the standard bartowski quant ladder (F16 → IQ2_XXS) for `llama.cpp`.

	> Source model: [`ManniX-ITA/Qwen3.6-27B-Omnimerge-v4`](https://huggingface.co/ManniX-ITA/Qwen3.6-27B-Omnimerge-v4) (BF16 weights, model card with full benchmarks and methodology).
	> NOT a quant of clean Qwen/Qwen3.6-27B — these GGUFs contain the v4 merge.

	All quants made using imatrix with [calibration data v5](https://gist.github.com/bartowski1182/82ae9b520227f57d79ba04add13d0d0d), the same calibration set bartowski uses for the Qwen3.6 base release — so quality fingerprints are directly comparable to bartowski's `Qwen_Qwen3.6-27B-GGUF` repo.

	## Why this merge exists

	Same-base DARE-TIES (Omnimerge_v2 method) merge of Qwen/Qwen3.6-27B + 3 Qwen3.6 fine-tunes. Direct successor to [`ManniX-ITA/Qwen3.5-27B-Omnimerge-v2`](https://huggingface.co/ManniX-ITA/Qwen3.5-27B-Omnimerge-v2) on the newer Qwen3.6 base, with `mlp.{gate,up,down}_proj` copied verbatim from clean Qwen3.6 (the "MLP-passthrough" surgery) to defend against a Qwen3.6-specific reasoning-tag fragility we found during forensic delta inspection. See the [v4 model card](https://huggingface.co/ManniX-ITA/Qwen3.6-27B-Omnimerge-v4) for the full story, scripts, and benchmark methodology.

	## Benchmark headline (Q6_K, head-to-head vs Qwen3.6 base + Omnimerge-v2)

	All scored under identical llama.cpp + lm_eval conditions (`--reasoning-format deepseek --reasoning-budget 8192 --parallel 2`, raw `/v1/completions`, no chat template).

	\| Benchmark \| Qwen3.6 base Q6_K (bartowski) \| Omnimerge-v2 (Qwen3.5 base) \| Omnimerge-v4-MLP (this) \| Δ vs base \| Δ vs v2 \|
	\|---\|---\|---\|---\|---\|---\|
	\| HumanEval pass@1 (164q) \| 84.76% \| 79.27% \| 84.76% \| 0.00 pp \| +5.49 pp \|
	\| MBPP pass@1 (500q) — corrected\* \| 57.60% \| 74.60% \| 73.40% \| +15.80 pp \| −1.20 pp \|
	\| GPQA Diamond pass@1 (flex) \| not measured \| 69.19% (full 198q) \| ≈ 84.75% (partial 177q‡) \| — \| ≈ +15.5 pp \|

	\* MBPP scores are post-`<think>`-stripping (lm_eval's raw scorer SyntaxErrors on literal `<` in `exec(prompt+completion+tests)`). See the [v4 model card](https://huggingface.co/ManniX-ITA/Qwen3.6-27B-Omnimerge-v4) for the per-model recovery breakdown.
	‡ GPQA crashed on the at-budget reasoning tail (aiohttp lifecycle bug in lm_eval); 192/198 cached, 177 matched, headline expected to land in the 82-86% band.

	## Available Quantizations

	All 27 files (F16 + 26 imatrix-quantized tiers, ~417 GB total) are uploaded and ready. `imatrix.dat` (used for every quant) is in the repo root for audit and reproduction.

	\| Quantization \| File size \| Use case \|
	\|---\|---\|---\|
	\| F16 (full precision) \| 50.11 GB \| Conversion source / lossless reference \|
	\| Q8_0 \| 26.63 GB \| Highest fidelity, large \|
	\| Q6_K_L \| 21.14 GB \| Q6_K with embed/output at Q8_0 \|
	\| Q6_K \| 20.57 GB \| Recommended high tier — eval methodology used this \|
	\| Q5_K_L \| 18.64 GB \| Q5_K_M with embed/output at Q8_0 \|
	\| Q5_K_M \| 17.91 GB \| Strong fidelity, balanced \|
	\| Q5_K_S \| 17.40 GB \| Slightly smaller K-mix \|
	\| Q4_K_L \| 16.29 GB \| Q4_K_M with embed/output at Q8_0 \|
	\| Q4_1 \| 15.91 GB \| Legacy 4-bit, dense \|
	\| Q4_K_M \| 15.41 GB \| Recommended balanced tier for most users \|
	\| IQ4_NL \| 14.72 GB \| Importance-aware 4-bit non-linear \|
	\| Q4_K_S \| 14.52 GB \| K-mix small variant \|
	\| Q4_0 \| 14.41 GB \| Legacy 4-bit \|
	\| IQ4_XS \| 14.05 GB \| IQ4 extra-small \|
	\| Q3_K_XL \| 13.42 GB \| Q3_K_L with embed/output at Q8_0 \|
	\| Q3_K_L \| 13.36 GB \| 3-bit K-mix large \|
	\| Q3_K_M \| 12.39 GB \| 3-bit K-mix medium \|
	\| IQ3_M \| 11.72 GB \| Importance-aware 3-bit medium \|
	\| Q3_K_S \| 11.24 GB \| 3-bit K-mix small \|
	\| IQ3_XS \| 11.15 GB \| IQ3 extra-small \|
	\| Q2_K_L \| 11.13 GB \| Q2_K with embed/output at Q8_0 \|
	\| IQ3_XXS \| 10.42 GB \| IQ3 extra-extra-small \|
	\| Q2_K \| 9.98 GB \| 2-bit K-mix \|
	\| IQ2_M \| 9.32 GB \| Importance-aware 2-bit medium \|
	\| IQ2_S \| 8.72 GB \| IQ2 small \|
	\| IQ2_XS \| 8.47 GB \| IQ2 extra-small \|
	\| IQ2_XXS \| 7.85 GB \| IQ2 extra-extra-small (smallest) \|

	## How to Use

	With [llama.cpp](https://github.com/ggml-org/llama.cpp):

	```bash
	# Recommended args for reasoning-tag-emitting models (matches the eval methodology):
	llama-server \
	-m Qwen3.6-27B-Omnimerge-v4-Q4_K_M.gguf \
	-c 32768 -ngl 99 -t 12 --no-warmup \
	--reasoning-format deepseek --reasoning-budget 8192
	```

	Swap `Q4_K_M` for any tier from the table above. `Q6_K` matches the methodology used in our published evals; `Q4_K_M` is the typical "balanced" choice for most users.

	For multimodal (vision) inference: the `mmproj` projector is in [`bartowski/Qwen_Qwen3.6-27B-GGUF`](https://huggingface.co/bartowski/Qwen_Qwen3.6-27B-GGUF) and works with this model unchanged (vision tower is preserved verbatim from the base).

	With [ollama](https://ollama.ai): use a Modelfile pointing to one of the GGUFs above, or HF direct load.

	## imatrix.dat

	The `imatrix.dat` (~14 MB) used to generate every quant in this repo is uploaded alongside the GGUFs at the repo root. Reproducible, auditable.

	## Reproducing

	See [`scripts/`](https://huggingface.co/ManniX-ITA/Qwen3.6-27B-Omnimerge-v4/tree/main/scripts) on the source v4 model repo:

	- `dare_ties_merge.py` — main merger (auto-detects Qwen3.6 base via `output_gate_type` and applies MLP-skip)
	- `v4_mlp_passthrough.py` — post-process: rebuild merged dir with MLP layers from base
	- `quantize_gguf.py` — the script that built this repo

	For dense (non-Gemma-4-MoE) models, pass `--exclude CD-Q6_K,CD-Q5_K_M,CD-Q4_K_M,CD-Q3_K_M,CD-Q2_K` to skip ContribDynamic tiers (those require Gemma 4 expert-contribution maps).
