Key Points

  • The paper introduces ATAR (Attention-Aligned Reasoning), a method that uses the model’s latent reasoning structure to steer attention toward important intermediate steps and the original prompt.
  • It argues that in long “reasoning chains,” crucial context can be buried and under-attended, causing errors, and ATAR is designed to mitigate this failure mode.
  • Experiments on six benchmarks show ATAR outperforms prior state-of-the-art approaches, with reported gains up to 15.39% absolute improvement.
  • The authors find that “non-reasoning” models using ATAR can match or surpass the performance of dedicated reasoning models of similar size on most benchmarks.
  • Ablation results suggest the attention-alignment component is a key contributor and that improvements persist across different attention-steering backends.

Abstract

Large Language Models (LLMs) tend to generate a long reasoning chain when solving complex tasks. However, as the reasoning chain extends, critical intermediate steps and the original prompt will be buried in the context, receiving insufficient attention and leading to errors. In this work, we present ATAR, a novel reasoning method that leverages the inherent reasoning structure to steer LLM attention. Our experiments show that ATAR outperforms SOTA methods across six benchmarks, achieving up to 15.39% absolute improvement. Furthermore, with ATAR, "non-reasoning" models achieve comparable or even better performance compared to reasoning models of the same size in most benchmarks. Finally, our ablation studies show that the attention alignment component contributes significantly, and that these improvements are persist under different attentionsteering backends.
