Why it matters

Existing long-video benchmarks lack inter-clip spatiotemporal continuity, so they cannot assess memory across days or weeks. EgoMonth provides a temporal-grounded evaluation for long-term memory in MLLMs, revealing that even top models remain far below human performance.

Motivation

Recent advances in Multimodal Large Language Models (MLLMs) have led to substantial progress in video understanding, accompanied by a growing number of long video benchmarks.
