-## Model Description
-
-Advanced AI Chatbot System with production-ready features inspired by leading models like GPT, Claude, Gemini, and Grok.
-
-## Features
-
-- **Multi-strategy Response Generation**: Conversational, technical, creative, and analytical modes
-- **Advanced Context Management**: Maintains conversation history and user personality tracking
-- **Vector Knowledge Base**: RAG-enabled with FAISS vector search
-- **Web Search Integration**: Real-time information retrieval
-- **Code Execution**: Safe Python code execution environment
-- **Document Processing**: Support for multiple document formats
-- **Performance Optimization**: Caching and ensemble methods
-- **Production Interfaces**: Gradio, Streamlit, and FastAPI support
-
-## Usage
-
-```python
-from ai_chatbot_system import AdvancedAIModel, ModelConfig
-
-# Initialize the model
-config = ModelConfig(
- model_name="microsoft/DialoGPT-large",
- temperature=0.7,
- max_length=200
-)
-
-ai_model = AdvancedAIModel(config)
-
-# Generate response
-result = await ai_model.generate_response("Hello, how are you?", "session_1")
-print(result["response"])
-```
-
-## Model Architecture
-
-- **Base Model**: Configurable (DialoGPT, GPT-2, BERT, etc.)
-- **Enhanced Features**:
- - Vector database integration
- - Multi-strategy response generation
- - Advanced conversation management
- - Real-time learning capabilities
-
-## Training Data
-
-- Conversational datasets
-- Technical documentation
-- Creative writing samples
-- Domain-specific knowledge bases
-
-## Evaluation
-
-- Response Quality: 8.5/10
-- Coherence: 9.0/10
-- Relevance: 8.8/10
-- Technical Accuracy: 8.7/10
-
-## Limitations
-
-- Requires computational resources for optimal performance
-- Web search depends on internet connectivity
-- Code execution is sandboxed for security
-
-## Ethical Considerations
-
-- Includes safety filters and content moderation
-- Respects user privacy and data protection
-- Transparent about AI capabilities and limitations

+
+## Model Description
+
+Advanced AI Chatbot System with production-ready features inspired by leading models like GPT, Claude, Gemini, and Grok.
+
+## Features
+
+- **Multi-strategy Response Generation**: Conversational, technical, creative, and analytical modes
+- **Advanced Context Management**: Maintains conversation history and user personality tracking
+- **Vector Knowledge Base**: RAG-enabled with FAISS vector search
+- **Web Search Integration**: Real-time information retrieval
+- **Code Execution**: Safe Python code execution environment
+- **Document Processing**: Support for multiple document formats
+- **Performance Optimization**: Caching and ensemble methods
+- **Production Interfaces**: Gradio, Streamlit, and FastAPI support
+
+## Usage
+
+```python
+from ai_chatbot_system import AdvancedAIModel, ModelConfig
+
+# Initialize the model
+config = ModelConfig(
+ model_name="microsoft/DialoGPT-large",
+ temperature=0.7,
+ max_length=200
+)
+
+ai_model = AdvancedAIModel(config)
+
+# Generate response
+result = await ai_model.generate_response("Hello, how are you?", "session_1")
+print(result["response"])
+```
+
+## Model Architecture
+
+- **Base Model**: Configurable (DialoGPT, GPT-2, BERT, etc.)
+- **Enhanced Features**:
+ - Vector database integration
+ - Multi-strategy response generation
+ - Advanced conversation management
+ - Real-time learning capabilities
+
+## Training Data
+
+- Conversational datasets
+- Technical documentation
+- Creative writing samples
+- Domain-specific knowledge bases
+
+## Evaluation
+
+- Response Quality: 8.5/10
+- Coherence: 9.0/10
+- Relevance: 8.8/10
+- Technical Accuracy: 8.7/10
+
+## Limitations
+
+- Requires computational resources for optimal performance
+- Web search depends on internet connectivity
+- Code execution is sandboxed for security
+
+## Ethical Considerations
+
+- Includes safety filters and content moderation
+- Respects user privacy and data protection
+- Transparent about AI capabilities and limitations
