3 SIGMA CODE [3σ]

Engineering the Exception.

### 👁️ ABOUT THE CHANNEL **3 Sigma Code** is a repository of high-signal engineering demonstrations. I deconstruct "Black Box" AI systems and rebuild them from scratch in Python. **Core Philosophy:** * **No Hype:** If I can't build it, I don't talk about it. * **Code First:** Theory is optional. Implementation is mandatory. * **Systems Thinking:** It's not just about the model. It's about the pipeline. --- ### 📡 TOPICS I COVER | Category | What We Build | | :--- | :--- | | **🧠 LLM Internals** | Transformers, Attention Mechanisms, Tokenizers | | **📚 RAG Systems** | Vector DBs, Hybrid Search, Context Window Optimization | | **🤖 Agents** | Tool Use, Planning Loops, Multi-Agent Orchestration | | **⚖️ Evaluation** | LLM-as-a-Judge, Cosine Similarity, Automated Red-Teaming | | **⚙️ MLOps** | Model Serving, Quantization, Fine-Tuning (LoRA/QLoRA) | --- ### 🛠️ THE STACK
