Researchers have developed MM-StanceDet, a novel multi-agent framework designed to improve multimodal stance detection by integrating retrieval augmentation for better contextual grounding. This system employs specialized agents for analyzing text and images, a debate stage for exploring different perspectives, and a self-reflection mechanism for robust decision-making. Experiments across five datasets show MM-StanceDet significantly outperforms existing methods, highlighting the effectiveness of its multi-agent architecture in handling complex multimodal challenges. Separately, a study comparing prompting and multi-agent methods for LLM-based stance detection found that prompt-based inference generally outperforms agent-based debate, despite requiring fewer API calls. This research also indicated that model scale, up to 32B parameters, has a greater impact on performance than the chosen method, and that specialized reasoning-enhanced models do not consistently outperform general models of similar size.
