Researchers have introduced AdaFuse, a novel framework designed to enhance the performance of large language models (LLMs) through adaptive ensembling during decoding. Unlike existing methods that use fixed fusion strategies, AdaFuse dynamically selects appropriate fusion units based on the decoding context, allowing for mid-generation adaptation. The framework employs an uncertainty-based criterion to decide when to ensemble, invoking a diversity-aware scaling strategy to explore alternative continuations and improve ensemble quality. Experiments show AdaFuse consistently outperforms strong ensemble baselines across various tasks, including question answering, arithmetic reasoning, and machine translation, with an average relative improvement of 6.88%.
