Make a brand visual kit with ChatGPT Images 2.6
Make a matching hero banner, social posts and YouTube thumbnail from one brand brief with ChatGPT Images 2.6, in about 25 minutes.

What you need
Step 1: Set up a brand project
4 minA project keeps your brand brief and files in every chat, so you never paste them again.
- In the ChatGPT sidebar, select New project and name it after your brand.
- Open the more options menu (•••), select Project settings, and paste the brief below as the instructions.
- Add your logo and one past image to the project as files.
Your brand briefYou make images for [BRAND NAME], a [WHAT IT IS] for [WHO IT'S FOR]. Colors: [HEX 1] main, [HEX 2] accent, [HEX 3] background. Use only these. Tone: [3 WORDS, e.g. calm, bold, friendly]. Style: [e.g. flat illustration with clean shapes, or bright product photos]. Type: [e.g. heavy rounded sans-serif headings, plain sans-serif body]. Rules: render any text in quotes exactly as written, once. Add no other text, no watermarks and no other brands' logos. Leave clear space around text.
You should see your brand project in the sidebar, with the brief saved in its settings.
New chats ignore the brief?
Start each chat from inside the project, not from the main chat list. Project instructions apply only to chats in that project.
Have a mascot? Upload it and ask ChatGPT to save it as a reference with a name. Then type @ and that name in any later chat.
Step 2: Make the hero banner
5 minThe hero sets the look, and every other asset in the kit copies it.
- Open a new chat inside your brand project.
- Paste the prompt below, fill in the brackets, and send it.
- Wait for the image. It can take a minute or more, and you can keep chatting meanwhile.
Your promptCreate a wide 16:9 hero banner for our website home page. Show [SUBJECT, e.g. a hand holding our product on a clean desk] on the right. Put the headline "[YOUR TAGLINE]" on the left in large type, with clear space around it. Use the brand colors and style from this project. No other text.
You should see one wide banner in your colors, with your tagline on the left.
A word in the tagline is misspelled?
Reply with the right word in quotes, spelled out letter by letter. Ask ChatGPT to change only that word and keep everything else the same.
Step 3: Refine it one change at a time
4 minSmall, single edits stop the parts you like from drifting.
- Select the banner to open the editor, choose Select, and highlight the area to change.
- Describe one change, such as "make this area darker", and say what must stay the same.
- Repeat until it's right, then choose Save in the editor.
You should see the same banner, with only the area you picked changed.
The edit changed parts you didn't select?
Highlights aren't always exact. Choose Undo, select a smaller area, and add "keep the layout, text and colors the same" to your request.
Step 4: Make the social posts
5 minBuilding from the approved hero keeps colors, type and style the same across every size.
- In the same chat, paste the prompt below to make a square post.
- Open the new image in the editor, choose Aspect ratio, and pick a tall shape for a story version.
- Do the same for any other size you post in.
Your promptUsing the approved hero banner as the style guide, make a 1:1 square social post about [TOPIC]. Headline: "[SHORT HEADLINE]". Same colors, type and illustration style as the banner. Keep all text inside the frame with a margin on every side.
You should see a square post and a tall story version that clearly belong with the banner.
The tall version cuts off the headline?
Ask ChatGPT to keep the headline fully inside the frame with a margin on every side. Shorter headlines fit square and tall shapes more easily.
Step 5: Make a YouTube thumbnail
4 minThumbnails show up small on phones, so they need bigger words and fewer parts than the hero.
- In the same chat, paste the prompt below with your video title and a few big words.
- Zoom out in your browser to check the thumbnail at a small size.
Your promptMake a 16:9 YouTube thumbnail for a video called "[VIDEO TITLE]". Show only these words, very large: "[3 TO 5 WORDS]". One clear subject on the right, high contrast, our brand colors and style. It must read clearly at a small size. No other text.
You should see a bold thumbnail with a few large words you can read even when it's tiny.
It's too busy to read at a small size?
Ask ChatGPT to remove everything except the subject and the words, and to make the words twice as large.
Step 6: Save the kit and reuse it
3 minA folder of approved files is your kit, and the project keeps the look for next time.
- Open each approved image and select Save to download it.
- Name each file by asset and size, such as hero-16x9.png, and keep them in one folder.
- For the next campaign, start a new chat in the same project. Your brief and logo are already there.
You should see one folder with your banner, social posts and thumbnail, all in the same style.
ChatGPT also keeps every image under Images in the sidebar. Deleting the chat that made an image removes it from there too.
You get
A matching set of brand images, from hero banner to thumbnail, plus a project that keeps your look for the next one
