Common Questions

Frequently asked

What does Flux PuLID cost per generation?

Flux PuLID costs $0.04 per generation on muapi. Each image generated—regardless of aspect ratio or complexity of style transfer—incurs a single charge. There are no subscription fees or per-pixel costs.

How accurate is the identity preservation across different styles?

PuLID uses advanced face encoding to maintain consistent facial features across varying art styles, lighting conditions, and contexts. While extreme stylization (e.g., cartoon or abstract) may naturally reduce photo-realism, facial identity markers remain recognizable and consistent.

Can I use PuLID for professional or commercial purposes?

Yes. PuLID-generated images can be used commercially in marketing, entertainment, personal branding, and other applications. Verify your image rights and muapi's terms of service for your specific use case.
