Researchers have introduced AMOR (Adaptive Metacognitive Output Router), a novel hybrid AI architecture that selectively employs attention mechanisms based on predictive uncertainty. This approach augments a recurrent backbone with entropy-gated attention blocks that activate only when the model's output entropy surpasses a dynamic threshold. Tested on the FineWeb-Edu dataset, AMOR variants, utilizing Mamba2 or Gated DeltaNet backbones, achieved superior common-sense reasoning scores compared to existing recurrent, attention-only, and fixed-schedule hybrid models. The architecture also demonstrated improved retrieval performance and maintained the long-context robustness characteristic of its recurrent components, outperforming Transformer and other hybrid models under distribution shifts.
