InstantCharacter is a personalized character image generation workflow for ComfyUI, built on top of the FLUX Diffusion Transformer (DiT). Think of InstantCharacter as enabling high-fidelity character rendering from a single reference image and a text prompt—while preserving facial identity, pose adaptability, and creative styling through the InstantCharacter framework.
Whether you're generating stylized portraits, sequential keyframes, or imaginative poses in diverse environments, InstantCharacter gives creators precise control with unmatched consistency. The InstantCharacter workflow brings Tencent's breakthrough personalization technology to ComfyUI, combining identity preservation with creative flexibility.
Character Identity Preservation: InstantCharacter maintains character appearance while flexibly creating high-quality images based on text instructions. The InstantCharacter workflow achieves excellent balance between identity consistency and text controllability.
Advanced Feature Extraction: InstantCharacter utilizes SigLIP for fine-grained identity details and DINOv2 for robust background-resistant features. This dual encoder approach provides comprehensive character information through InstantCharacter's multi-level extraction.
Scalable DiT Architecture: Built specifically for Diffusion Transformers, InstantCharacter employs full Transformer architecture for efficient FLUX interaction. InstantCharacter uses timestep-aware Q-former and cross-attention mechanisms for superior performance.
Style Compatibility: InstantCharacter demonstrates excellent compatibility with style LoRAs across anime, realistic, and artistic styles. The InstantCharacter framework maintains core identity features while adapting to diverse visual styles.
