Ideogram’s Character Reference model enables consistent character generation using just one reference image. Upload a clear character portrait—and you can place that character in unlimited scenes, styles, poses, or narratives with visual fidelity maintained across all outputs.
About this model
Ideogram's Character Reference model solves the consistency problem in character-driven workflows. Upload a single clear character portrait, and the model learns that character's face, features, clothing, and overall appearance. You can then place that character in unlimited new scenes, styles, poses, and narratives—maintaining visual fidelity and recognizability across every generation.
Perfect for illustrators, comic creators, game developers, and storytellers who need consistent characters across multiple images. With muapi's per-generation pricing and no subscription, you can generate dozens of character variations and story scenes at low cost, paying only for the images you create.
