ComfyUI Extension: ComfyUI_InfiniteYou

ComfyUI_InfiniteYou Introduction

ComfyUI_InfiniteYou is an extension designed to integrate the InfiniteYou model into ComfyUI, a powerful visual AI engine. Developed by the ZenAI team, this extension allows AI artists to leverage the state-of-the-art (SOTA) zero-shot identity preservation capabilities of InfiniteYou, a model created by ByteDance. The extension is built on the FLUX framework and aims to provide seamless identity preservation in image generation tasks. It is particularly useful for artists looking to maintain identity similarity in their creative projects, offering features like face swapping and combining to predict future children.

How ComfyUI_InfiniteYou Works

At its core, ComfyUI_InfiniteYou utilizes the InfiniteYou model, which is designed to preserve identity in generated images. The model works by injecting identity features into a base model through a component called InfuseNet. This process ensures that the generated images maintain a high degree of identity similarity while also achieving good text-image alignment and aesthetic quality. The extension operates within the ComfyUI environment, which uses a node-based interface to create complex workflows without requiring coding skills. This makes it accessible to AI artists who can visually design their image generation processes.

ComfyUI_InfiniteYou Features

ComfyUI_InfiniteYou offers several key features:

• Face Swap: This feature allows you to swap faces in images, maintaining the identity of the original face while integrating it into a new context. This can be particularly useful for creating unique artistic compositions or exploring different visual styles.
• Face Combine: This feature predicts the appearance of future children by combining the facial features of two individuals. It is a creative tool for artists interested in exploring genetic combinations and visualizing potential outcomes.
• Zero-Shot Identity Preservation: The extension excels in preserving the identity of subjects in generated images without requiring prior training on specific identities. This is achieved through the InfuseNet component, which enhances identity similarity.

ComfyUI_InfiniteYou Models

The extension includes two main models, each serving a specific purpose:

• sim_stage1: This model prioritizes higher identity similarity, making it ideal for tasks where maintaining the original identity is crucial. It is suitable for projects that require precise face preservation.
• aes_stage2: This model focuses on better text-image alignment and enhanced aesthetics. It is designed for projects where the visual appeal and integration of text prompts are more important.

Both models are available in the safetensors format for easy integration with ComfyUI.

• Face Combine Feature: Also added in March 2025, this feature predicts future children by combining facial features, offering a unique tool for exploring genetic visualizations.
• First Version Release: The initial version of the extension was released in March 2025, providing a robust foundation for identity-preserving image generation.

Troubleshooting ComfyUI_InfiniteYou

If you encounter issues while using ComfyUI_InfiniteYou, consider the following solutions:

• Model Loading Errors: Ensure that all required models are downloaded and placed in the correct directories as specified in the installation instructions.
• Performance Issues: If the extension is running slowly, check your system's resources and consider optimizing memory usage by following tips from the Diffusers memory reduction guide.
• Unexpected Results: If the generated images do not meet your expectations, try adjusting the InfuseNet conditioning scale and guidance start parameters to fine-tune the output.
