        ### 🏗️ Architecture Overview

        

        **🧠 Intelligent Routing System**

        - Domain detection based on prompt analysis

        - Dynamic encoder selection optimized for content type

        - Load balancing across specialized encoder pools

        

        **🔧 Production Features**

        - Comprehensive error handling and fallback modes

        - Real-time performance monitoring and statistics

        - Memory optimization and CUDA support

        - Detailed logging and debugging capabilities

        

        **📊 Specialized Domains**

        - **Medical & Healthcare** • **Legal & Regulatory** • **Code & Technical**

        - **Science & Research** • **Creative Writing** • **Business & Finance**

        

        Built with ❤️ using Gradio, PyTorch, and the Mamba architecture
