Updated: June 26, 2026

Mastering ChatGPT Image Model 1.5

Most people type a vague description and hope for something usable.
This guide gives you 50+ proven prompt formulas — tested, structured,
and ready to copy — for every image type professionals actually need.

Photo portraits. Product shots. Illustrations. Logos. UI mockups.
Thumbnails. Diagrams. Backgrounds. Each formula tells Image Model 1.5
exactly what to produce — no guessing, no wasted credits, no
re-prompting 10 times to get one usable result.

With ChatGPT Image Model 1.5, the real power is control.
These formulas give you that control — from your very first prompt.


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.


Which Style Are You Generating? Start Here.

Before writing a single word, decide which of these 4 style
categories your image falls into. Each needs a different
approach in your prompt:

Photo / Photorealistic
For portraits, product shots, lifestyle images, office interiors.
Key words to include: “photorealistic”, lens size (35mm/85mm),
aperture (f/1.8), lighting source, skin texture detail.
Constraint to always add: “no beauty smoothing, no watermark”

Illustration / Flat Design
For blog images, SaaS hero sections, onboarding flows, diagrams.
Key words to include: “flat illustration”, “vector style”,
“minimalist”, color palette, “white background, no text”
Constraint to always add: “no realism, no gradients unless specified”

Logo / Icon
For brand marks, app icons, favicon-style graphics.
Key words to include: “logo design”, “minimal”, “single color”
or “two-color”, “clean lines”, “scalable icon style”
Constraint to always add: “no text, no gradients, no shadows”

UI / Mockup
For dashboards, app screens, landing page wireframes.
Key words to include: “UI mockup”, “flat UI style”, specific
layout description (sidebar, header, cards), accent color
Constraint to always add: “no lorem ipsum, no placeholder text”

Identify your category first → then use the matching prompt
formulas from the examples below.
