Researchers have introduced MEME, a new benchmark designed to evaluate the memory capabilities of LLM-based agents in persistent environments. MEME addresses limitations in prior work by defining six tasks that cover multi-entity interactions and evolving memory states, including novel challenges like dependency reasoning and deletion. Initial evaluations across six memory systems revealed significant performance collapses on dependency reasoning tasks, with even advanced LLMs and prompt optimization failing to bridge the gap. While one system using Claude Opus 4.7 showed partial success, its high cost indicates practical scalability challenges for current memory solutions. AI
