# Claude Code with DeepSeek v3.1 API Tutorial ## 📋 Video Overview This video provides a comprehensive tutorial on integrating the DeepSeek V3.1 model (released on January 21, 2025) into Claude Code, enabling cost-effective and efficient AI-powered programming assistance. It's a complete integration guide designed for beginners and developers, demonstrating the entire process of flexible third-party API integration. --- ## 🎯 Key Content Points ### 1. **Prerequisites** **Obtaining DeepSeek API Key:** - Visit the DeepSeek Open Platform to apply for an API KEY - ⚠️ Important Note: API Keys are displayed only once, so immediately copy and save it to a text file - The demonstration key shown in the video will be deleted after recording **Setting Up Claude Code Environment:** - Deploy Claude Code runtime environment locally - Docker version is recommended for environment setup - Version used in the video: Claude Code 1.0.93 ### 2. **Critical Configuration Steps** **Important Notes for Existing Users:** - Check the `.claude` directory under your user directory - If a `settings.json` file exists, temporarily rename it (e.g., add a `_1` suffix) - Reason: This file contains Claude Code's default environment variables, and its presence can prevent certain commands from working - You can rename it back after use to continue with your previous settings ### 3. **Implementation Process** **Command Configuration:** 1. Copy the complete startup command from official documentation (single-line command) 2. Replace the TOKEN placeholder with your actual DeepSeek API Key (starts with "SK") 3. Navigate to your Claude Code project folder 4. Execute the modified command to start the service **First-Time Use Tips:** - Initial run will present some configuration options - These basic configurations are straightforward; simply follow the prompts ### 4. **Functionality Testing & Demonstration** **Test Case 1: Model Identification** - Question: What model are you? - Response: Confirmed as DeepSeek Chat model (i.e., DeepSeek V3.1) **Test Case 2: Practical Programming Task** - Task: Generate a user login page Layout (wireframe) - Results: - Successfully generated PC-end Layout - Included Chinese documentation - Automatically adapted mobile version - Excellent performance for basic programming tasks ### 5. **Cost Analysis** **Actual Usage Cost Reference:** - Number of requests: 6 - Token consumption: Approximately 60,000 - Total cost: ¥0.01 CNY (one Chinese cent) - **Conclusion: Extremely low cost, ideal for learning and development** --- ## 💡 Core Advantages Summary 1. **Flexible Third-Party Integration**: Claude Code supports flexible third-party API integration without excessive restrictions 2. **Ultra-Low Usage Cost**: DeepSeek V3.1 offers highly competitive pricing 3. **Stable Performance**: Suitable for handling basic to moderately complex programming tasks 4. **Beginner-Friendly**: Recommended as a starting point for learning AI programming --- ## 🎓 Target Audience - AI programming beginners - Individual developers seeking cost reduction - Tech enthusiasts learning and experimenting with AI-assisted programming - Development teams requiring stable and economical AI programming assistants --- ## 📚 Related Resources - Official documentation: dpit.lib00.com (search "3.1" for complete documentation) - Companion video: DeepSeek API Key application tutorial - Companion video: Docker-based Claude Code runtime environment setup - Coming soon: Claude Code practical series videos (for beginners) --- ## 🔧 SEO Keywords `DeepSeek V3.1`, `Claude Code`, `API Integration`, `AI Programming`, `Third-Party Model Integration`, `Low-Cost Development`, `Docker Deployment`, `Programming Assistant Tools`, `AI-Powered Development`, `Code Generation`, `Developer Tools`
