Model Quick Reference

Model	Best For
Nano Banana Pro	Overall best, text + icons, App Store icons
GPT Image 1.5

Conversational iteration, natural language |
| Ideogram | Perfect text rendering |
| Midjourney v7 | Artistic icons only (no text) |

iOS App Icons (Liquid Glass)

iOS 26 uses Liquid Glass design. Use this prompt structure:

Validation Loop (MANDATORY)

NEVER deliver without visual review. Every AI output must be inspected before sharing.

1. 1. Generate → 2. Look at the actual image → 3. Check for issues → 4. Fix or regenerate → 5. Repeat (max 5-7 attempts)

Common fixes:

• - Unwanted padding → Crop
• Elements cut off → Regenerate with "centered composition"
• Text garbled → Use Nano Banana/Ideogram or add manually
• Too complex → Simplify prompt

If 5-7 attempts fail, change model or strategy entirely.

Universal Truths

AI output is a starting point. Every AI logo needs vectorization, cleanup, and manual text refinement. Never use raw output as final.

Test at small sizes early. If it doesn't work at 32px, simplify. Most real-world usage is small.

Text handling varies. Only Nano Banana and Ideogram reliably render text. For Midjourney, generate icon-only.

Simple logos last. Nike, Apple, McDonald's. Complexity dates quickly and fails at small sizes.

Before Finalizing

• - [ ] Works in black and white
• [ ] Readable at 32px (favicon test)
• [ ] Vectorized (SVG), not just PNG
• [ ] All variants created (horizontal, stacked, icon-only)
• [ ] Text manually refined, not AI-generated
• [ ] Tested on dark and light backgrounds
