About this model
Flux PuLID is an innovative image-to-image model that enables consistent face rendering across different styles, scenes, and contexts without requiring any model fine-tuning or training. By providing a reference portrait or facial image, PuLID generates new visuals that preserve your subject's identity with high fidelity while adapting to entirely new backgrounds, artistic styles, or compositional contexts. This enables powerful creative use cases—reimagining a person's appearance in different scenarios, styles, or roles without losing recognizable identity.
Flux PuLID is perfect for portrait artists, fashion photographers, personal branding, entertainment and gaming, and anyone creating identity-consistent visuals across multiple contexts. Accessible through muapi's unified API with simple per-generation pricing, it eliminates the friction of fine-tuning or complex identity preservation workflows.
