GPT-4o Image — OpenAI 4o Image Generation Online
The model behind ChatGPT’s 2025 image wave: precise instruction following, faithful style transfer, readable text.
GPT-4o Image is OpenAI’s native image generation inside GPT-4o, the model that powered ChatGPT’s image launch in March 2025 and the restyled-photo wave that followed. You can run GPT-4o Image here on any Premium or Pro plan for 30 credits per image, with up to four reference photos for edits and style transfers. No ChatGPT account is required.
What is GPT-4o Image?
GPT-4o generates images natively rather than calling a separate diffusion model: the same network that reads your words renders the pixels, token by token. That is why it binds attributes to objects so reliably. Ask for a green triangle to the left of a red cube and that is what you get, in the order you asked for.
It reached the mainstream in March 2025, when ChatGPT users restyled family photos into consistent art styles and flooded every social feed. The strengths behind that trend still hold up: GPT-4o Image keeps the content of a source photo intact while changing its style, and it renders readable text in posters, comics, and labels. OpenAI later exposed the same capability to developers under the API name gpt-image-1.
Honest caveat: this is the slowest model on our platform. A generation usually takes three to five minutes because the model renders autoregressively. We poll for up to six minutes and the wait is normal, not a bug. If you want most of the quality in a fraction of the time, GPT Image 2 is the newer, faster option.
GPT-4o Image outputs at 1K in three formats: square 1:1, landscape 3:2, and portrait 2:3. It accepts up to four reference images. At 30 credits per image, a Premium plan covers about 133 generations a month.
GPT-4o Image features
Instruction following
Counts, positions, and attribute bindings land as written. Prompts with several explicit constraints are where 4o earned its reputation.
Style transfer that preserves content
Upload a photo and name a style. Faces, poses, and composition survive the restyle, which is exactly what made it go viral in 2025.
Readable in-image text
Posters, comics, and labels come out with correct spelling far more often than diffusion models of the same generation.
Reference-image editing
Up to four reference photos per generation for edits, combinations, and character-consistent series.
GPT-4o Image examples with prompts
Real, unretouched images generated with GPT-4o Image (OpenAI GPT-4o). The caption under each image is the exact prompt used.
GPT-4o Image: before and after
The left image was generated with GPT-4o Image, then edited by GPT-4o Image itself using this prompt: “Change the perfume bottle to frosted emerald green glass and switch the marble surface to dark slate, keep the same composition and lighting”.
How to use GPT-4o Image

What GPT-4o Image is best at
Photo restyling
Turn portraits and family photos into consistent illustration styles while keeping faces and poses recognizable.
Multi-constraint prompts
Scenes with exact object counts, positions, and colors. 4o follows the brief instead of averaging it away.

Panel layouts and poster copy with readable text, generated in one pass.
Character series
Reuse reference photos across generations to keep a character consistent through a whole set.
GPT-4o Image FAQ
What is GPT-4o Image?
GPT-4o Image is OpenAI’s image generation built natively into GPT-4o. It launched in ChatGPT in March 2025 and is known for following instructions precisely and restyling photos while keeping their content. On Nano Banana AI it costs 30 credits per 1K image.
Is GPT-4o Image the same as gpt-image-1?
Yes. gpt-image-1 is the API name OpenAI gave the same GPT-4o image capability when it opened to developers in April 2025. Product pages usually call it 4o Image or GPT-4o Image.
Why does GPT-4o Image take so long?
The model renders images token by token inside the language model instead of using a fast diffusion pass. Three to five minutes per image is normal. If you need results in seconds, use GPT Image 2 or Nano Banana instead.
Is GPT-4o Image free?
No. Nano Banana AI has no free tier. GPT-4o Image is available on Premium ($19.99/month, 4,000 credits) and Pro ($29.99/month, 10,000 credits) at 30 credits per image.
What aspect ratios does GPT-4o Image support?
Three: 1:1 square, 3:2 landscape, and 2:3 portrait, all at 1K. There is no 16:9 option; 3:2 is the closest. For 16:9 or 4K, use GPT Image 2.
Can GPT-4o Image edit my photos?
Yes. Attach up to four reference photos and describe the change or the target style. Content preservation during restyles is the model’s signature strength.
GPT-4o Image vs GPT Image 2: which is better?
GPT Image 2 is newer, much faster, sharper on text, and reaches 4K with eight aspect ratios. GPT-4o Image remains worth using for its style-transfer character and strict instruction following at 1K. Both cost about the same here (30 credits at 1K).
Do I need a ChatGPT Plus subscription?
No. Nano Banana AI runs the model through its own integration. Any Premium or Pro plan here includes GPT-4o Image alongside the rest of the catalog.
