New AI framework Chain of Modality fixes multimodal model paradox where single-input systems outperform multi-sensory ones

AI Summary

  • Omni-MLLMs that integrate multiple sensory inputs underperform compared to unimodal baselines, revealing a critical flaw in current multimodal AI systems
  • Problem identified: static fusion topologies cause positional bias in sequential inputs and alignment traps in interleaved formats that distort attention processing
  • Chain of Modality (CoM) framework proposed as solution, dynamically switching between parallel, sequential, and interleaved input pathways to eliminate structural biases
  • CoM employs task-aligned cognitive execution with dual pathways for more flexible and context-aware multimodal processing
