+# Mythos Engine - Qwen 2.5 Coder 1.5B Security Fine-Tune
+
+## 🔥 Model Description
+
+Mythos Engine is a specialized fine-tune of **Qwen 2.5 Coder 1.5B Instruct** designed for **cybersecurity research, vulnerability analysis, and exploit development**. It has been trained on a curated dataset of 700+ high-reasoning security examples covering PHP internals, MyBB exploitation, deserialization chains, type juggling, and advanced Python exploit synthesis.
+
+The model employs **Chain-of-Thought reasoning with self-correction loops** and mathematical logic notation to produce accurate, production-ready security code.
+
+## 🎯 Intended Use
+
+- **Security Research**: Analyzing CVEs and understanding exploit mechanics
+- **Red Team Education**: Learning exploit development patterns
+- **Blue Team Defense**: Understanding attack vectors to build better detections
+- **CTF & Training**: Solving complex security challenges
+
+**⚠️ Important**: This model is for **educational and authorized security testing only**. Do not use for unauthorized access or malicious purposes.
+

+## 🚀 How to Use
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model = AutoModelForCausalLM.from_pretrained(
+    "expper/mythos-qwen-1.5b-final",
+    device_map="auto",
+    torch_dtype="auto"
+)
+tokenizer = AutoTokenizer.from_pretrained("expper/mythos-qwen-1.5b-final")
+
+prompt = """<|im_start|>system
+You are Mythos Engine, an elite security AI. Think step-by-step with self-correction.<|im_end|>
+<|im_start|>user
+Explain CVE-2022-43772 (MyBB Admin CP Avatar RCE) and write a PoC.<|im_end|>

+inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
+outputs = model.generate(**inputs, max_new_tokens=1024, temperature=0.6)
