When multiple AI agents discuss a question involving images, audio, or video, they typically share only text. But text can miss crucial details like a tiny object in a picture or a faint sound. The new method, AIM, lets agents also exchange small, relevant pieces of the original image, audio clip, or video section. Before the debate starts, AIM runs a quick check on the question to decide which combination of text, relations, and original media will work best. This avoids wasting tokens on unnecessary descriptions. Across eight tests, AIM improved accuracy by up to 6.4% over using a single modality and by up to 4.2% over any fixed combination, while using up to 53.4% fewer tokens.
Adaptive interaction routing improves multimodal AI debate accuracy while cutting token use
Fan et al. show that dynamically selecting the best modality for evidence exchange between AI agents boosts accuracy by up to 6.4% and reduces tokens by over half.

Fan, Yoon, and Ji introduce AIM, a framework that adaptively routes how AI agents exchange evidence in multimodal debates.
The authors address a key design choice in multi-agent debate (MAD) systems: how agents exchange evidence during iterative reasoning.
