Real Work AI Coding: Deepseek vs ChatGPT vs Claude

# Real Work AI Coding: Deepseek vs ChatGPT vs Claude ## Video Overview This video presents a real-world frontend development scenario where the author tests four mainstream AI coding assistants (GPT-4o-mini, Claude 3.5 Sonnet, Deepseek V3, and Deepseek R1) with identical code refactoring tasks while integrating Baidu Analytics into a Vue3 project. The comparison provides valuable insights into each AI's practical coding capabilities. --- ## Test Scenario & Task **Development Context**: The author needed to refactor scattered Baidu Analytics code from `main.ts` and `router/index.ts` into a centralized `tongji.ts` file for better maintainability. **Code Complexity Factors**: - Vue3 production environment detection - Global variable handling (`window._hmt`) - Async logic in route guards - Nested conditional statements - Redundant parameters and async keywords requiring optimization **Prompting Strategy**: The author used concise prompts without excessive details to test each AI's contextual understanding capabilities. --- ## Detailed AI Performance Analysis ### 🥇 GPT-4o-mini (1st Place) **Strengths**: - ✅ Successfully modularized code into three independent functions - ✅ Intelligently removed redundant if-nesting - ✅ Automatically optimized unnecessary async keywords and parameters - ✅ Correctly understood Vue Router navigation guard mechanisms - ✅ Even caught and corrected typos in the author's code (main.ts naming error) - ✅ Provided alternative solutions (`return true` vs `next()`) **Code Quality**: Well-structured, production-ready with minimal adjustments **Best For**: Production environment refactoring requiring high-quality output --- ### 🥈 Deepseek R1 (2nd Place) **Strengths**: - ✅ Similar to GPT-4o-mini in handling if-nesting optimization - ✅ Added TypeScript global variable declarations (`declare global`) - ✅ **Unique Advantage**: Displays complete reasoning process—extremely valuable for learners - ✅ Provided detailed code explanations and best practice recommendations **Areas for Improvement**: - ⚠️ Didn't remove redundant async and some parameters - ⚠️ Contains duplicate if-checks (already present in track page view) - ⚠️ Unnecessary blank lines in code **Special Feature**: Visible reasoning process ideal for learning and understanding AI logic --- ### 🥉 Claude 3.5 Sonnet (3rd Place) **Performance Characteristics**: - ✅ Code runs successfully with complete basic functionality - ⚠️ Didn't fully consolidate code as requested (routing logic remained in router/index.ts) - ⚠️ Preserved original if-nesting without optimization - ⚠️ Didn't remove redundant parameters and async keywords **Assessment**: Functionally adequate but lacks optimization compared to top performers --- ### 4️⃣ Deepseek V3 (4th Place) **Performance Characteristics**: - ⚠️ Extremely fast response (1-2 seconds) but compromised quality - ⚠️ Nearly copied original code with minimal refactoring - ⚠️ Failed to identify redundant parameters and logic issues - ⚠️ Didn't achieve proper code encapsulation and modularization **Assessment**: Not suitable for actual code refactoring work --- ## Key Findings & Recommendations ### Code Quality Ranking 1. **GPT-4o-mini** - Best choice, most comprehensive optimization 2. **Deepseek R1** - Close second, high learning value 3. **Claude 3.5** - Mid-tier, usable but requires manual optimization 4. **Deepseek V3** - Not recommended for production environments ### Deepseek R1's Unique Value Proposition - **Reasoning Visualization**: Complete inference chain transparency - **Educational Merit**: Helps beginners understand refactoring logic - **Debug-Friendly**: Makes AI logical gaps easily identifiable ### Usage Recommendations - **Production Environment**: Prioritize GPT-4o-mini - **Learning Scenarios**: Leverage Deepseek R1's reasoning process - **Rapid Prototyping**: Claude 3.5 is acceptable - **Avoid**: Deepseek V3 for code refactoring tasks --- ## Technical Stack Covered Vue3, TypeScript, Router Guards, Baidu Analytics Integration, Code Refactoring Patterns, AI-Assisted Development --- ## SEO Keywords AI coding comparison, ChatGPT vs Claude, Deepseek R1 review, Vue3 code refactoring, AI code assistant, frontend development tools, GPT-4o-mini, LLM programming capabilities, real-world development scenarios, AI pair programming, code optimization
