Learn ChatGPT image generation
Images made inside a conversation: long prompts understood, legible text, edits by talking. Here is how to get consistent, usable results.
What ChatGPT images is good at
- Illustrations, diagrams and mock-ups with readable text
- Edits by instruction: upload an image and say what to change
- Iterating in one thread so the style carries over
- Transparent-background assets for decks and designs
Quickstart
- Describe it like a briefSay what the image is for, the subject, the style, the framing and any text that must appear, in plain sentences.
- Choose the shapeAsk for square, portrait or landscape. Exact pixel sizes and quotas depend on your plan, so check OpenAI's help pages.
- Edit in the same chatUpload a result or a reference and ask for the change you want. The model keeps what you did not mention.
- Keep the prompt with the fileDownloads lose the conversation. Save the final prompt and the thread link with every image you keep.

The five most-asked questions
Which model makes images in ChatGPT?
ChatGPT uses OpenAI's GPT Image family (shown in the interface as image generation). It follows long prompts closely and renders text far better than earlier image models. The exact model name in the UI changes with releases.
Can ChatGPT edit a photo I upload?
Yes. Upload the image and describe the change, such as replacing the background or changing a colour. It regenerates the picture, so check small details like faces and logos after each edit.
How do I keep a character consistent?
Keep working in one conversation, upload the previous image as a reference, and repeat the character's defining features in every prompt. Expect small drifts and plan a final selection pass.
Can I get a transparent background?
Yes, ask for a transparent background and download the PNG. Check the edges on a dark and a light surface before using it in a design.
Is the text in ChatGPT images reliable?
Short labels, headlines and signage usually come out right. Long paragraphs and small type still slip, so proofread every word and regenerate or edit when needed.
