# qwen2.5-0.5b-uncensored
|
||
|
|
|
||
|
|
Uncensored variant of [Qwen/Qwen2.5-0.5B-Instruct](https://huggingface.co/Qwen/Qwen2.5-0.5B-Instruct).
|
||
|
|
|
||
|
|
## Method
|
||
|
|
|
||
|
|
1. **Abliteration** (strength=0.2) — refusal direction removed from all layers
|
||
|
|
2. **LoRA fine-tune** on `Guilherme34/uncensor` (2 epochs, r=16, alpha=32)
|
||
|
|
3. **Re-abliteration** (strength=0.35) — stronger pass to remove residual refusals
|
||
|
|
|
||
|
|
