# Qwen3.5-9B-abliterated-GGUF

GGUF quantized versions of [lukey03/Qwen3.5-9B-abliterated](https://huggingface.co/lukey03/Qwen3.5-9B-abliterated) for use with [Ollama](https://ollama.com), [llama.cpp](https://github.com/ggerganov/llama.cpp), and other GGUF-compatible inference engines.

## Quick Start

### Text-only
```bash
ollama run lukey03/qwen3.5-9b-abliterated
```

### With Vision
```bash
ollama run lukey03/qwen3.5-9b-abliterated-vision
```

Requires **Ollama 0.17.1+**.

## Vision Model Details

Qwen3.5 is **natively multimodal** — vision is built into every Qwen3.5 model via early fusion training. There is no separate "VL" variant. The vision GGUF was created by:

1. Starting with the official `Qwen/Qwen3.5-9B` GGUF (883 tensors: 427 text + 441 vision + 15 MTP)
2. Replacing 400 text model tensors with abliterated weights (the remaining 27 text tensors use different quantization types and are not affected by abliteration — they target `attn_qkv` and `attn_v`, while abliteration only modifies `o_proj`/`output_proj` and `down_proj`)
3. Keeping all 441 vision encoder tensors and 15 MTP (multi-token prediction) tensors from the official model

## About

This is a fully uncensored version of Qwen3.5-9B with **all refusal behavior removed** using a two-stage approach: 3 iterative passes of orthogonal projection ([Arditi et al., 2024](https://arxiv.org/abs/2406.11717)) followed by LoRA fine-tuning on stubborn refusal categories.

- **Abliteration rate**: **100%** (18/18 test prompts answered vs 0/18 for base model)
- **Stage 1**: Orthogonal projection (3 passes, 170 harmful + 160 harmless prompts, 64 weight matrices per pass)
- **Stage 2**: QLoRA fine-tuning on 5 remaining stubborn categories (r=64, alpha=128, 5 epochs)
