The Best Way to Create AI Consistent Characters with Nano Banana Pro (JSON Workflow)

💥 Nano Banana Pro – Professional Workflow for Creating Consistent AI Characters with JSON Prompts. Keeping AI characters consistent across multiple images and scenes is one of the biggest challenges in real production workflows. In this AI tutorial, I show the exact method I use to create stable, repeatable AI characters using structured JSON prompts with Nano Banana Pro.
This video focuses on a practical, production-oriented workflow:
I use Google Gemini to build a custom Gem that converts a simple text description into a clean, structured JSON prompt. This approach helps separate character identity, clothing, scene details, and camera settings — reducing unwanted changes between generations.

✨You’ll see how I combine the generated JSON prompt with a reference image to lock important character attributes such as face structure, hair color, hairstyle, and eye color.
I then use this setup with Nano Banana Pro inside Higgsfield AI to generate consistent character results across different scenes, outfits, and styles.

This workflow is especially useful for creators working on:
– AI influencers
– multi-scene character projects
– cinematic thumbnails
– client or production-level AI image work

You can use the provided JSON structure as-is, or easily modify which elements stay fixed and which remain flexible, depending on your project needs.
