Codex AI social media design prompts are structured visual briefs that work — but there's one thing to understand first: Codex AI is a code generation tool. It produces prompts, not images. To actually render these visuals you need to pair these prompts with an AI image generation platform. Below you'll learn how to generate the images, save the best prompts as reusable Skills, and get all 10 formats that perform best in 2026.
How to Generate Images from These Prompts
These prompts are ready to use with any AI image generation tool. The fastest workflow: copy a prompt below, open iMini AI, select an image model such as Seedream 4.0 or Nano Banana Pro, and generate in under 30 seconds.
Step-by-step:
- Copy a prompt from the list below
- Go to iMini AI and open Image Generation
- Paste the prompt into the input field
- Set the output aspect ratio for your platform (1:1 for Instagram, 9:16 for TikTok, 16:9 for YouTube)
- Generate — refine the wording and regenerate until the result matches your vision
Save Any Prompt as a Skill for Instant Reuse
Once a prompt consistently delivers strong results, save it as a Skill in iMini AI. Skills turn any prompt into a one-click template — so your weekly LinkedIn visual or monthly campaign header takes seconds instead of starting from scratch.
To create a Skill: run the prompt in iMini AI → open the Canvas panel → click Save as Skill → name it (e.g. "LinkedIn Thought Leadership Visual") → access it anytime from your Skill library.
