I build a retrieval-first agent memory DB. Two papers just said retrieval is the wrong default.
Two recent research papers suggest that relying solely on retrieval for agent memory is suboptimal for long-horizon tasks. One paper, Mem-π, demonstrates that training a model to generate guidance on demand, rather than retrieving static entries, can improve performance by over 30% on web-navigation tasks. The other, MINTEval, highlights that retrieval systems struggle with contradictory or revised information in large contexts, leading to significant accuracy drops. The author of mnemo, an agent memory database, acknowledges these limitations and plans to implement an interference-evaluation harness and a resolver to prioritize the most recent, uncontradicted facts, while maintaining an auditable retrieval log.

IMPACT New research challenges the default retrieval-first approach for agent memory, potentially shifting development towards generative or hybrid models for improved performance on complex, long-horizon tasks.
