When Agents Remember Their Mistakes: The End of AI Amnesia

What if an AI agent could learn from every single failure, every clumsy workaround, every brilliant recovery, and feed that experience back into its own future performance?Today’s LLM-powered agents suffer from a fundamental flaw: amnesia. They repeat the same mistakes, miss the same shortcuts, and rediscover the same solutions over and over. A new framework from IBM Research changes that by mining agent execution trajectories for three types of actionable knowledge: strategy tips from clean successes, recovery tips from failure-and-fix sequences, and optimization tips from tasks completed inefficiently.On the AppWorld benchmark, agents equipped with this learned memory improved scenario goal completion by up to 14.3 percentage points on unseen tasks, and by a staggering 28.5 points on complex multi-step challenges. That is a 149% relative increase, with zero model changes.Inspired by the work of Gaodan Fang, Vatche Isahagian, K. R. Jayaram, Ritesh Kumar, Vinod Muthusamy, Punleuk Oum, and Gegi Thomas, this episode was created using Google’s NotebookLM.Read the original paper here: https://arxiv.org/abs/2603.10600
