Humans can complete high-quality creative work, such as drawing a picture or creating a video based on text, and editing images or videos according to textual requirements. In the earlier period of artificial intelligence, the “best of N” strategy was often utilized to leverage the creative capability of multiple visual creators, which was computationally inefficient and labor-intensive. With the emergence of large language models (LLMs), the LLM-based agent dynamically plans the invocation of tools to accomplish creative tasks. However, these agent systems struggle to achieve optimal tool planning and creative performance, especially complex creative tasks. Toward these issues, we propose MAGiC, a LLM-Powered Multi-Agent Framework for Visual Generation and Editing to unleash Visual Creativity. MAGiC addresses users’ creation requirements through the collaboration of four modules, i.e., task assignment, planning, execution, and evaluation, with each controlled by agents configured for different roles. Specifically, the task assignment module iteratively releases new tasks based on the user requirements and its completion progress. The Planning module configures the corresponding Planner for different types of tasks, and these Planners create detailed plans for the tasks they are responsible for. The Execution module iteratively executes the plans set by the Planners. The evaluation module assesses the result obtained by the execution module to prevent errors from affecting subsequent tasks. Finally, MAGiC illustrates excellent creativity on multiple tasks, especially complex ones, and the high scalability of MAGiC is an initial step in applying multi-agent systems to llm-based visual system.
