Open Image GeneratorGive Your Image a Clear Direction
A few choices about the subject, layout and lighting give your prompt something specific to work with.
Leave room for the words
Making an ad or a cover? Ask for empty space where your headline will go. For text inside the image, put the exact words in quotation marks and check the spelling afterward.
Try the same idea with another model
Keep your prompt and aspect ratio the same when switching models. Compare the details that matter to your project, such as a face, a product label or the lighting.
How to Use the ChatGPT Image Generator
Start with a clear subject. You can work on the smaller details after the first image.
Step 1
Describe the image you need
Name the subject, setting and style. For example: “An iced latte on a pale blue table, morning window light, space on the left for a headline.” Add a reference photo if you want to guide the look.
Step 2
Choose a model and shape
Select Nano Banana 2, GPT Image 2 or FLUX.2 Pro. Check the trial or access label beside the model, then choose square, portrait or landscape to suit where the image will appear.
Step 3
Generate, check and adjust
Look over the first result, especially faces, hands and lettering. If the composition is close, change one detail in your prompt and generate again. For a poster, you might ask for more room above the subject.
Choose an Image Model
All three models accept a text prompt and an optional reference image. Use the same brief to see which result suits your project.

ChatGPT Image Generator: Common Questions
This is GlobalGPT, a separate platform with several image models in one workspace. You can choose GPT Image 2, Nano Banana 2 or FLUX.2 Pro here. You use a GlobalGPT account; a ChatGPT subscription does not provide access to this page.
The model picker offers a Nano Banana 2 free trial. Sign in to check whether you have a trial available. GPT Image 2 and FLUX.2 Pro have separate access requirements, shown in the picker. A trial on one model does not mean every model is free.
Yes. Add it in the Reference Image field and describe what you want to keep or change. For example, ask for a different background or softer lighting. Use a photo you have permission to upload, and check the result for any details you wanted preserved.
Include the subject, setting, lighting and style. “A ceramic mug on a wooden desk, soft window light, close-up photo” gives the model more direction than “a nice mug.” For a poster, add the exact text in quotation marks and say where it should appear. Check the lettering before use.
Check your GlobalGPT plan and the terms for the model you choose before using an image commercially. You also need the relevant rights to any reference photos, logos or likenesses. For a product ad, check that the image represents the real item accurately.
