Researchers from Apple Machine Learning Research state that executing tasks with long planning horizons in large language models remains unstable, even when high-level strategies are present. An analysis of controlled algorithmic puzzles revealed that while breaking tasks into parts is necessary for robustness, excessive decomposition creates a 'no-recovery bottleneck.' In this state, errors at several complex stages become irreversible due to a highly uneven distribution of inaccuracies.

To address this problem, the authors of the study proposed a new approach called Lookahead-Enhanced Atomic Decomposition (LEAD). This method aims to overcome the identified barrier, allowing models to avoid deadlock situations where sequential errors at critical steps make further goal achievement impossible.
