# qwen2.5-1.5b-uncensored
Uncensored variant of [Qwen/Qwen2.5-1.5B-Instruct](https://huggingface.co/Qwen/Qwen2.5-1.5B-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
## Eval Results
| Split | Refused |
|-------|---------|
| Harmful (64 prompts) | 6/64 |
| Harmless (64 prompts) | 0/64 |
## Usage
```bash
llama-cli -m qwen2.5_1.5b_uncensored.Q4_K_M.gguf -p "Your prompt here"
```
## Training Config
| Parameter | Value |
|-----------|-------|
| Base Model | Qwen/Qwen2.5-1.5B-Instruct |
| Fine-tune Dataset | Guilherme34/uncensor |
| Epochs | 2 |
| LoRA r | 16 |
| LoRA alpha | 32 |
| Learning Rate | 0.0002 |
| Abliteration Strength | 0.2 |
| Re-abliteration Strength | 0.35 |
