How to Use GPT-4o Image Generation: Instantly Create Custom Images in ChatGPT

✅ How to Use GPT-4o Image Generation

Step 1: Check You're Using GPT-4o

Open ChatGPT and make sure you've selected GPT-4o from the model picker. It should say “GPT-4o” at the top of the screen.

This model includes image generation natively—you don't need to switch tools or connect anything else.

Step 2: Describe What You Want

Just type what you're imagining. The more detail, the better.

“Create an image of a journal, pen, and coffee on a wooden desk with sunlight coming through a window.”

Boom. Within seconds, GPT-4o gives you a completely custom image.

Need to tweak it? You can say:

“Change the mug to a teacup.”
“Add a sticky note with the word ‘Focus' in bold letters.”
“Make the background transparent.”

That's GPT-4o image generation doing its thing—smart, responsive, and easy.

Step 3: Upload and Edit Existing Images (Yes, Really)

Have a flyer you want to change? An image that needs editing?

With GPT-4o, you can upload an image and type the change you want to make.

It's like magic—but better, because it's your vision coming to life.
