EvoMemBench: Why AI Agent Memory Must Evolve, Not Just Remember

The article introduces EvoMemBench, a benchmark evaluating AI agent memory across four dimensions — task-internal knowledge, task-internal execution, cross-task knowledge, and cross-task execution — revealing five key findings: memory isn't always better than raw context, helps more on hard tasks, is critical for long-horizon execution, retrieval does not equal revision, and no single memory type fits all tasks. It concludes with five engineering principles for building effective memory systems.
