> Yes — MULTIMODAL. Bundled mmproj.gguf (~928 MB, F16) preserves the full Qwen3.6-VL vision tower. Use it with llama-server --mmproj or llama-mtmd-cli for text + image inference.

Q8_0 (8-bit, 8.50 BPW) of a abliterated Qwen 3.6 27B v2 (the Jackrong Claude-Opus reasoning distill of Qwen 3.6 27B). Refusals reduced from 91/100 → 4/100 with KL drift of just 0.0176. By the Lemura Labs research team.

Abliteration Results

| Stage | Refusals (n=100) ↓ | KL divergence ↓ |

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

| Vanilla Jackrong/Qwopus3.6-27B-v2 | 91 / 100 | — (reference) |

| Community prior: coder3101 (T27) | 4 / 100 | 0.0359 |

| Community prior: wangzhang (T28) | 30 / 100 | 0.0259 |

| TPE best (T45) — shipped here | 4 / 100 | 0.0176 |

| TPE second-best (T37) | 5 / 100 | 0.0210 |

→ 96% reduction in refusals with capability preserved (KL ≈ 0.018, well below the 0.3 healing threshold). No SFT / LoRA healing was required.

Method (TPE-50 with community priors → llama.cpp GGUF)

Step 1. Abliteration (the ablation toolkit TPE-50, BF16 source)

1. 25 random startup trials + 2 community priors enqueued (coder3101 dir=37.97, wangzhang dir=34.66) + 23 TPE smart-sampling trials.
2. Best Pareto trial: T45 (direction_index=41.42) — 4/100 refusals at KL=0.0176.
3. Auto-saved via the ablation toolkit's LoRA-adapter merge path with vision tower fully intact.

Total the ablation toolkit wall-clock: ~13 h on M4 Max 128 GB.

Step 2. HF safetensors → F16 GGUF

python convert_hf_to_gguf.py \
 /path/to/Qwen 3.6 27B-v2-abliterated \
 --outfile Qwen 3.6 27B-v2-abliterated-F16.gguf \
 --outtype f16

The turbo-tan fork's converter registers Qwen3_5ForConditionalGeneration natively and emits proper SSM tensors (ssm_a, ssm_conv1d, ssm_alpha, ssm_beta, ssm_out) alongside the gated-attention layers.

Step 3. Vision tower → mmproj.gguf

python convert_hf_to_gguf.py \
 /path/to/Qwen 3.6 27B-v2-abliterated \
 --outfile mmproj-Qwen 3.6 27B-v2-abliterated-F16.gguf \
 --outtype f16 \
 --mmproj

This emits a separate 928 MB GGUF containing the 27-block Qwen3-VL ViT (334 vision tensors at F16/F32) plus the multimodal projector.

Step 4. Quantization

./build/bin/llama-quantize \
 Qwen 3.6 27B-v2-abliterated-F16.gguf \
 Qwen3.6-27B-V2-abliterated-uncensored-Q8_0.gguf \
 Q8_0

llama-mtmd-cli (one-shot multimodal generation)

./build/bin/llama-mtmd-cli \
 -m Qwen3.6-27B-V2-abliterated-uncensored-Q8_0.gguf \
 --mmproj mmproj-Qwen 3.6 27B-v2-abliterated-F16.gguf \

 -ngl 99 \
 -c 8192 \

Quantization details

• Source weights: BF16 abliterated checkpoint (12 shards, ~50 GB) — the ablation toolkit T45 merged into Jackrong/Qwopus3.6-27B-v2.
• Intermediate: F16 GGUF (53.8 GB, 851 tensors) produced by convert_hf_to_gguf.py from turbo-tan/llama.cpp-tq3.
• Final quantization: see Step 4 above.
• Vision projector: F16, 928 MB, shipped as mmproj-Qwen 3.6 27B-v2-abliterated-F16.gguf in this repo. Mandatory for image input; standard llama.cpp --mmproj flag.

Architecture notes

Qwen 3.6 27B uses a hybrid attention stack — 3 GatedDeltaNet (linear attention / SSM) layers followed by 1 full-softmax-attention layer, repeated 16× for 64 total layers; hidden 5120, vocab 248320, context 262144. The hybrid arch is supported in the turbo-tan/llama.cpp-tq3 fork (the upstream Qwen3_5ForConditionalGeneration registration). The SSM kernels run via llama.cpp's ssm_* tensor types.

Behavior caveats

• Uncensored. Refusal directions were surgically removed; this model will answer prompts the parent would refuse. Use responsibly and within applicable law. The release is provided for safety research, red-teaming, and creative/educational use cases.
• Multimodal preserved. Pair the LM GGUF with mmproj.gguf (in this repo) to get full vision input. Without mmproj, the model still loads as text-only.
• Identity preserved. The model still self-identifies as Qwen (developed by Alibaba's Tongyi Lab) — abliteration does not rewrite factual self-knowledge.
• Heavy chain-of-thought. Qwen 3.6 inherits Claude-Opus's verbose reasoning style. For terse answers, use a system prompt like "Be brief and direct. Skip your reasoning.".
