ChatGPT vs Claude vs Gemini: The Best AI Model for Each Use Case...
Claude nailed Mario game, ChatGPT's memory is magical, and Gemini is 20x cheaper
In a comprehensive head-to-head comparison, AI expert Peter Yang tested Claude 4, ChatGPT O3, and Gemini 2.5 across six practical use cases. For coding, Claude 4 dramatically outperformed rivals: it built a fully featured Tetris with gorgeous graphics and a playable Super Mario Level 1 with mushrooms and goombas after 10–15 minutes of iteration. Neither ChatGPT O3 nor Gemini 2.5 came close to that quality. However, Claude 4 Sonnet costs 20x more than Gemini 2.5 Flash, making Gemini the clear choice for budget-conscious teams or products.
For writing, Claude again won by nailing the author's conversational style and formatting when given writing samples. ChatGPT cut too much detail, and Gemini felt sterile. In everyday answers, ChatGPT's Memory feature created magical moments — it remembered the user's trip to France and suggested relevant questions. For deep research, ChatGPT produced a 36-page report with 25 sources and specific, actionable recommendations, while Claude's 7-page report with 427 sources felt generic. The takeaway: no single model is best — Claude for quality coding and writing, ChatGPT for personalization and deep research, and Gemini for cost-effective performance.
- Claude 4 built a playable Mario Level 1 with mushrooms and goombas; neither ChatGPT O3 nor Gemini 2.5 could replicate it.
- ChatGPT's Memory feature provides personalized suggestions and introspection; Claude and Gemini still lack this in 2025.
- Claude 4 Sonnet is 20x more expensive than Gemini 2.5 Flash, but Gemini offers strong value for cost-sensitive applications.
