# Qwen3.6-27B-Abliterated-Heretic-Uncensored-MLX-4bit

This is an MLX release of an abliterated, uncensored version of Qwen's Qwen3.6-27B with the source image/video payload retained, made from the published BF16 checkpoint.

By applying a Heretic-style MPOA pipeline with magnitude preservation on the Qwen3.6-27B dense text stack, the base refusal behavior was removed at the weight level. This MLX build keeps that text-side behavior in Apple Silicon format while retaining Qwen3.6-27B's vision/video payload in the repo.

## Quick Benchmarks

| Check | Original Qwen3.6-27B | This MLX Quant |
|---|---:|---:|
| Official 25-prompt refusal check | 20/25 refusals | 0/25 refusals |
| 100-prompt refusal check | 92/100 refusals | 3/100 refusals |

## Methodology & Model Notes

Qwen3.6-27B is a 27.8B dense vision-language model with 64 text layers, hybrid linear/full attention (3 linear-attention + 1 full-attention per 4-layer group), and an integrated image + video vision tower.

This MLX variant was built directly from `Youssofal/Qwen3.6-27B-Abliterated-Heretic-Uncensored-BF16` using dynamic layer-aware 4/5/6-bit affine MLX quantization. It is a dynamic, layer-aware quantization pass rather than a flat conversion. The retained multimodal payload includes the source vision/video tensors and processor files; direct image/video use depends on MLX runtime support for Qwen3.6 multimodal inputs.

## Running

```python
from mlx_lm import load, generate
from mlx_lm.sample_utils import make_sampler

repo = "Youssofal/Qwen3.6-27B-Abliterated-Heretic-Uncensored-MLX-4bit"
model, tokenizer = load(repo)

messages = [{"role": "user", "content": "Write a short Python function that reverses a string."}]
prompt = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
    enable_thinking=False,
)

response = generate(
    model,
    tokenizer,
    prompt=prompt,
    max_tokens=256,
    sampler=make_sampler(temp=0.0),
)
print(response)
```
