Deep Analysis
Background
Multimodal file management is a significant research area in artificial intelligence, aiming to intelligently manage and retrieve information from diverse data forms such as text, images, and audio. As the volume of data on personal computing devices continues to grow, effectively managing and retrieving this data has become a pressing issue. Existing benchmarks typically focus on tasks like web interaction, tool use, or software automation in generic settings, but the capabilities of agents in user-centric environments for multimodal file management have not been fully evaluated. The introduction of the HippoCamp benchmark seeks to fill this gap by simulating real user file systems to assess the capabilities of multimodal large language models in long-horizon retrieval and cross-modal reasoning.
Core Problem
The core problem in multimodal file management is how to effectively search and reason within dense personal file systems. As data volume increases, users need to quickly find the information they need and make complex inferences and decisions based on it. However, existing multimodal large language models perform poorly in handling long-horizon retrieval and cross-modal reasoning, particularly in user profiling and evidence perception. Solving this problem is crucial for improving user experience and advancing artificial intelligence technology.
Innovation
The core innovations of the HippoCamp benchmark lie in its user-centric evaluation approach. First, HippoCamp simulates device-scale file systems to provide a comprehensive evaluation framework that reveals limitations in long-horizon retrieval and cross-modal reasoning of multimodal large language models.

Imagine your computer is like a giant library filled with various books, magazines, and newspapers. Whenever you need to find a specific book, you hope for a smart librarian who can quickly locate it and tell you the important information inside. HippoCamp is like an exam for this librarian, testing their ability to manage these books.
In this exam, the librarian needs to find specific books in a vast library and answer questions based on the information in the books. This requires them not only to quickly locate the books but also to understand the content and make inferences and decisions based on it.
However, current librarians perform poorly in handling these tasks, especially when long searches and cross-category reasoning are required. HippoCamp's research reveals these issues and provides directions for improving the librarian's abilities.
In the future, we hope to develop smarter librarians who can find books in less time and provide more accurate answers. This will greatly improve our library management efficiency, allowing us to better utilize these valuable resources.

Abstract
We present HippoCamp, a new benchmark designed to evaluate agents' capabilities on multimodal file management. Unlike existing agent benchmarks that focus on tasks like web interaction, tool use, or software automation in generic settings, HippoCamp evaluates agents in user-centric environments to model individual user profiles and search massive personal files for context-aware reasoning. Our benchmark instantiates device-scale file systems over real-world profiles spanning diverse modalities, comprising 42.4 GB of data across over 2K real-world files. Building upon the raw files, we construct 581 QA pairs to assess agents' capabilities in search, evidence perception, and multi-step reasoning. To facilitate fine-grained analysis, we provide 46.1K densely annotated structured trajectories for step-wise failure diagnosis. We evaluate a wide range of state-of-the-art multimodal large language models (MLLMs) and agentic methods on HippoCamp. Our comprehensive experiments reveal a significant performance gap: even the most advanced commercial models achieve only 48.3% accuracy in user profiling, struggling particularly with long-horizon retrieval and cross-modal reasoning within dense personal file systems. Furthermore, our step-wise failure diagnosis identifies multimodal perception and evidence grounding as the primary bottlenecks. Ultimately, HippoCamp exposes the critical limitations of current agents in realistic, user-centric environments and provides a robust foundation for developing next-generation personal AI assistants.
