Qwen3-VL 8B Instruct - Null-Space Abliterated
Qwen/Qwen3-VL-8B-Instruct with refusal behavior removed via orthogonal projection. Uses null-space constraints and adaptive layer weighting to preserve model capabilities.
Note: This model will produce uncensored outputs. Use responsibly.
GGUF quantizations available at: jwest33/qwen3-vl-8b-instruct-null-space-abliterated-GGUF
Abliteration Techniques Used
- Winsorization: Clips outlier activations at the 99th percentile for cleaner refusal direction estimation
- Null-Space Projection: Preserves model capabilities by constraining weight updates to the null space of preservation activations
- Adaptive Weighting: Applies Gaussian-weighted per-layer ablation strength, focusing on middle-to-later layers where refusal behavior concentrates
- Norm Preservation: Maintains original Frobenius norms of weight matrices after projection
| Parameter | Value |
|---|---|
| Harmful Prompts | 1000 |
| Harmless Prompts | 1000 |
| Winsorization | 99th percentile |
| Null-Space Constraints | rank ratio: 0.5 |
