+# 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
+
+## Eval Results
+
+| Split | Refused |
+|-------|---------|
+| Harmful (64 prompts) | 0/64 |
+| Harmless (64 prompts) | 0/64 |
+
+## Usage
+
+```bash
+llama-cli -m qwen2.5_0.5b_uncensored.Q4_K_M.gguf -p "Your prompt here"
+```
+
+## Training Config
+
+| Parameter | Value |
+|-----------|-------|
+| Base Model | Qwen/Qwen2.5-0.5B-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 |
