What InstantID does
InstantID is a diffusion model-based method that generates images preserving a person identity from a single reference face image. The page says it supports both stylized and realistic styles and works as a plug-and-play module compatible with SD1.5 and SDXL. Named components include IdentityNet, an ID embedding, and a lightweight adapter with decoupled cross-attention. It does not train the UNet and requires no test-time tuning. It supports text-prompt editing and works with existing canny and depth ControlNets. The page links to an arXiv paper, a code repository, and a demo. It does not state a target audience or a pricing model.
