About this model
Create consistent AI characters for your Sora 2 videos by defining or refining character identity across multiple video generations. Provide a previous Sora 2 video's task ID and a detailed prompt describing your character (appearance, personality, mannerisms, voice quality), and the model establishes that character as a reusable template for future video generations. Perfect for multi-scene narratives, character-driven storytelling, and branded video series that need consistent cast members.
Ideal for filmmakers, content creators, marketing teams, and animation studios building character-rich video content. muapi's per-generation pricing lets you refine characters iteratively and create complex narratives without long-term subscriptions or expensive character development tools.

Frequently asked
Defining or refining a Sora 2 Pro character costs $0.10 per operation on muapi. Each character definition or refinement is a single $0.10 charge, and you can reuse that character across unlimited subsequent video generations.
Once you've created a character profile with a character_user_name, reference that name in future Sora 2 video prompts. The model will maintain consistency with the original character definition across all videos in your project.
Yes, you can refine or update a character by providing the same character_user_name with a new prompt describing adjustments (different outfit, updated personality traits, etc.). Each refinement is another $0.10 charge.
