Run time and cost

This model costs approximately $0.057 to run on Replicate, or 17 runs per $1, but this varies depending on your inputs. It is also open source and you can run it on your own computer with Docker.

This model runs on Nvidia L40S GPU hardware. Predictions typically complete within 59 seconds. The predict time for this model varies significantly based on the inputs.

InfiniteYou-FLUX

InfiniteYou is an AI model that preserves your facial identity while transforming your portrait into new contexts, styles, and settings.

About This Model

InfiniteYou addresses the challenges of identity-preserved image generation using Diffusion Transformer (DiT) technology. Key features include:

  • Identity Preservation: Maintains your facial identity while generating entirely new images
  • High Text-Image Alignment: Accurately reflects the details in your text prompts
  • Natural Integration: Avoids awkward face-pasting issues common in other models
  • Two Model Variants:
  • aes_stage2: Better text-image alignment and aesthetic quality
  • sim_stage1: Higher identity similarity for stronger likeness preservation

The model works by injecting identity features into the FLUX.1-dev base model via residual connections, allowing it to maintain your identity while applying new styles, backgrounds, clothing, and contexts.

Model Parameters

  • Model Version: Choose between identity similarity (sim_stage1) or better aesthetics (aes_stage2)
  • Enhancement Options: Optional realism and anti-blur LoRAs for additional quality improvements
  • Advanced Controls: Adjust identity strength and guidance parameters for fine-tuned results

Technical Architecture

InfiniteYou uses InfuseNet, a component that injects identity features into the DiT base model through residual connections. The model underwent a multi-stage training process including pretraining and supervised fine-tuning with synthetic single-person-multiple-sample data.

The plug-and-play design ensures compatibility with various approaches including ControlNets, LoRAs, and other enhancement techniques.
