Why it matters
Existing memory benchmarks report aggregate QA accuracy, failing to attribute errors to specific system components. MemFail provides fine-grained diagnostics for memory system design.
Motivation
Large language model (LLM) agents increasingly rely on external memory systems to remain consistent across long-horizon interactions, but little empirical work has been done to understand the specific failure modes and design choices that these systems present.
