+Web3AI is an AI-powered blockchain and Web3 development toolkit that integrates OpenAI's capabilities with blockchain technologies. Now featuring **GPT-5.1-Codex-Max** for enhanced code generation, analysis, and blockchain insights.
 
 ## 🌟 Features
 
 - **Node.js Backend**: Server-side JavaScript for Web3 applications
 - **OpenAI Integration**: AI-powered smart contract analysis, code generation, and blockchain insights
+- **GPT-5.1-Codex-Max Support**: Advanced AI model for superior code understanding and generation
 - **Python AI Scripts**: Advanced AI capabilities for blockchain development
 - **Modular Architecture**: Easy to extend with additional AI or blockchain features
+- **Configurable Models**: Support for multiple OpenAI models (GPT-3.5, GPT-4, GPT-5.1-Codex-Max)

+### 5. Choose Your AI Model (Optional)
+
+The project defaults to **GPT-5.1-Codex-Max**, which provides:
+- Superior code generation and analysis
+- Enhanced smart contract security insights
+- Better understanding of Web3 concepts
+- Advanced reasoning capabilities
+
+You can change the model by editing the `OPENAI_MODEL` variable in your `.env` file:
+- `gpt-5.1-codex-max` (default, recommended)
+- `gpt-4-turbo-preview` (alternative, also very capable)
+- `gpt-4` (stable alternative)

+## 🚀 GPT-5.1-Codex-Max Features
+
+GPT-5.1-Codex-Max is OpenAI's most advanced code-focused model, offering:
+
+### Enhanced Capabilities
+- **Superior Code Generation**: Create complex smart contracts and blockchain applications with minimal prompting
+- **Advanced Security Analysis**: Identify subtle vulnerabilities and security issues in smart contracts
+- **Deep Web3 Understanding**: Comprehensive knowledge of blockchain protocols, DeFi, NFTs, and Web3 patterns
+- **Contextual Awareness**: Better understanding of complex codebases and multi-file projects
+- **Detailed Explanations**: More thorough and educational responses about Web3 concepts
+
+### Use Cases
+1. **Smart Contract Development**: Generate production-ready Solidity code
+2. **Security Auditing**: Comprehensive vulnerability analysis and remediation suggestions
+3. **Code Review**: In-depth analysis of existing blockchain code
+4. **Learning Tool**: Detailed explanations of complex Web3 concepts
+5. **Architecture Design**: High-level system design for blockchain applications
+
+### Performance Notes
+- GPT-5.1-Codex-Max provides more detailed and accurate responses compared to earlier models
+- Response times may be slightly longer due to enhanced processing
+- Token limits are higher, allowing for more comprehensive analysis
+- Recommended for production applications and critical security analysis
