+
+## 🎯 What is This?
+
+This is **DeepSeek-Coder 6.7B Instruct** fine-tuned on the **SecureCode v2.0 dataset** - a code model specifically designed for **security analysis and vulnerability detection**.
+
+DeepSeek-Coder was trained on **2 trillion tokens** with a unique focus on code understanding and generation. Combined with SecureCode training, this model excels at:
+
+✅ **Identifying subtle security flaws** in complex codebases
+✅ **Generating hardened implementations** optimized for security
+✅ **Explaining vulnerability chains** with step-by-step attack demonstrations
+✅ **Providing remediation guidance** with defense-in-depth patterns
+
+**The Result:** A security-first code model that balances performance with specialized vulnerability detection capabilities.
+
+**Why Deep Seek-Coder?** This model offers:
+- 🔍 **Excellent code comprehension** - Trained specifically for understanding code structure
+- 🛡️ **Security-aware architecture** - Pre-training included security-focused code
+- ⚡ **Efficient inference** - Compact 6.7B size with strong performance
+- 🎯 **Balanced trade-off** - Better than 3B models, more efficient than 13B+
+- 💰 **Cost-effective** - Optimal performance-per-parameter ratio
+
+---
+
+## 🚨 The Problem This Solves
+
+**AI coding assistants produce vulnerable code in 45% of security-relevant scenarios** (Veracode 2025). DeepSeek-Coder SecureCode Edition addresses this by combining deep code understanding with security expertise.
+
+**Real-world impact:**
+- Equifax breach (SQL injection): **$425 million**
+- Capital One (SSRF): **100 million** records exposed
+- SolarWinds (auth bypass): **18,000** orgs compromised
+
+This model was specifically fine-tuned to prevent these vulnerability classes.
