The ULTIMATE ChatGPT Image Model 1.5 Guide to Prompting

Mastering ChatGPT Image Model 1.5

AI image generation is no longer about typing creative sentences and hoping for magic.

With ChatGPT Image Model 1.5, the real power is control.

If you work in AI tools, automation, SaaS, no-code, content systems, or marketing, this guide will help you generate consistent, professional images — not random art.

Let’s get practical.

How Image Model 1.5 Actually Works

Image Model 1.5 does not “imagine”.

It executes instructions.

Think of it as a:

very skilled designer
who follows your brief exactly
but never asks questions

Clear brief → great output
Vague brief → strange output

The Golden Prompt Structure (Always Use This)

Mentally follow this order:

1. Type of image
2. Main subject
3. Physical details
4. Environment
5. Camera setup
6. Lighting setup
7. Style & quality
8. Constraints (what NOT to do)

You don’t need to write headings.
Just think clearly.
