A complete tutorial on building a functional web application from scratch in Canvas, utilizing Thinking Mode for more complex coding logic.
Thinking Mode vs Fast Mode
GPT-5 in 'Thinking Mode' generates significantly higher-quality code (up to 800+ lines) compared to 'Fast Mode' or GPT-4o, which typically produce only 80-170 lines. This reduces the risk of UI bugs and broken buttons.
Visual Display Tips
By default, the AI might generate a plain UI. You can enhance the visual quality by requesting custom CSS or specific color themes in your follow-up prompt.
Benefits of React in Canvas
Use the React framework when asking the AI to build applications in Canvas, as the Canvas system is optimized to render React components flawlessly in real-time.
