AutoStudio addresses the challenge of maintaining subject consistency in multi-turn interactive image generation, a task where users iteratively refine image content. It targets researchers and developers working with text-to-image models, offering a framework to generate coherent image sequences with consistent subjects across multiple interactions.

How It Works

AutoStudio employs a novel training-free, multi-agent framework leveraging LLMs and Stable Diffusion. It comprises a subject manager for dialogue interpretation and context tracking, a layout generator for precise subject placement via bounding boxes, a supervisor for refinement suggestions, and a drawer for image synthesis. A key innovation is the Parallel-UNet, which enhances subject-aware feature exploitation through parallel cross-attention modules, alongside a subject-initialized generation method to preserve smaller subjects.

Quick Start & Requirements
