A new benchmark called MemPABench has been introduced to evaluate the memory capabilities of personal AI agents, specifically focusing on their ability to learn and act on user interaction preferences. The benchmark simulates long-horizon tasks and grounded users with various preferences over extended periods, testing how agents handle clarifications, confirmations, and autonomous actions. Initial evaluations of four memory systems across four LLM backbones revealed that current retrieval-based memory systems offer limited improvements over agents with no memory, and even file-based memory struggles with context and adapting to preference changes.
