+# Qwen3-4B-2507-Instruct-Uncensored-HauhauCS-Aggressive
+Qwen3 4B 2507 Instruct uncensored by HauhauCS.
+## About
+No changes to datasets or capabilities. Fully functional, 100% of what the original authors intended - just without the refusals.
+These are meant to be the best lossless uncensored models out there.
+## Aggressive vs Balanced
+**Aggressive** applies stronger uncensoring. Use this when you need fewer refusals and don't mind occasional quirks.
+For agentic coding or reliability-critical tasks, use the Balanced variant instead (coming soon).

+## Specs
+- 4B parameters (dense)
+- 262K context
+- Based on [Qwen/Qwen3-4B-Instruct-2507](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507)
+## Recommended Settings
+From the Qwen team:
+**Thinking mode (default):**
+- `temperature=0.6`
+- `top_p=0.95`
+- `top_k=20`
+- `min_p=0`
+**Non-thinking mode:**
+- Add `/no_think` at the end of your prompt, or
+- `temperature=0.7`
+- `top_p=0.8`
+- `top_k=20`
+- `min_p=0`
+**Important:**
+- Use `--jinja` flag for proper chat template handling
+- Thinking mode produces `<think>...</think>` tags before responses
+## Usage
+Works with llama.cpp, LM Studio, Jan, koboldcpp, Ollama, etc.
+```bash
+# llama.cpp example
+./llama-cli -m Qwen3-4B-2507-Instruct-Uncensored-HauhauCS-Aggressive-Q4_K_M.gguf \
