GPT Image 1.5 Prompt Guide

What Makes a Good Prompt#

GPT Image 1.5 understands natural language. You don't need special syntax or magic words. But specific prompts get better results than vague ones.

Bad prompt: "A nice picture" Good prompt: "Product photo of wireless headphones on white background, studio lighting, sharp focus"

Three rules:

  1. Be specific - describe what you see in your mind

  2. Add context - lighting, style, mood, camera angle

  3. Iterate - first try won't always be perfect
