Use Cases

• Professional Design: Create high-quality visuals for commercial projects
• Marketing & Advertising: Generate premium imagery for campaigns
• Digital Art: Produce gallery-quality digital artwork
• Product Concepts: Visualize product ideas and prototypes
• Editorial Content: Create unique illustrations for articles and publications

Tips for Best Results

1. Detailed Prompts: DALL-E 3 excels with comprehensive descriptions

   • Good: "A serene Japanese garden in autumn with red maple leaves falling onto a stone path, traditional wooden bridge over a koi pond, soft morning light filtering through bamboo"
   • Avoid: "A garden"

2. Quality vs Speed: Choose based on your needs

   • Standard: Faster generation, good for drafts and iterations
   • HD: Superior detail and clarity, ideal for final production

3. Style Selection:

   • Vivid: Perfect for creative, artistic, and eye-catching content
   • Natural: Better for realistic, documentary, or subtle imagery

4. Aspect Ratios: Match your use case

   • 1024x1024: Social media posts, avatars, balanced compositions
   • 1792x1024: Banners, headers, landscape photography
   • 1024x1792: Portraits, mobile-first content, vertical compositions

5. Prompt Enhancement: DALL-E 3 automatically enhances prompts

   • The model expands and improves your description
   • Check the revised_prompt in the response to see enhancements

Notes

• DALL-E 3 generates only 1 image per request (unlike DALL-E 2's multiple image capability)
• The model automatically enhances prompts for better results
• HD quality takes longer but provides significantly more detail
• Best suited for high-quality, professional image generation
• Excels at understanding and depicting complex scenes and concepts
