According to God of Prompt (@godofprompt), a direct comparison was conducted between ChatGPT, DeepSeek, and Gemini using the prompt 'Build an ecommerce site for premium laptop and mobile accessories using HTML5.' The test found that all three AI models could generate functional ecommerce UIs, but ChatGPT delivered the most visually appealing and user-friendly layout, with modern design elements and responsive features. DeepSeek produced clean code with strong structure but lacked advanced stylistic touches, while Gemini excelled at generating mobile-friendly interfaces. This analysis highlights the growing capabilities of generative AI in automating web UI development, offering new business opportunities for agencies and startups to rapidly prototype and launch ecommerce solutions using AI-generated code.
