VibeWorlding: Can Multimodal Agents Construct 3D Open Worlds End-to-End?

Yansong Ning, Jingwen Ye, Zhongkai Wu +5

Constructing an interactive 3D open world from a user query is important. However, existing methods are primarily evaluated on idealized, simple queries, making it difficult to sys…

HRBench: Benchmarking and Understanding Thinking-Mode Switch Strategies in Hybrid-Reasoning LLMs

Yansong Ning, Mianpeng Liu, Jingwen Ye +2

Hybrid-reasoning large language models (LLMs) expose explicit controls over reasoning effort, allowing users or systems to trade off answer quality against inference cost. However,…

AstroMind: A High-Fidelity Benchmark for Spacecraft Behavior Reasoning Based on Large Language Models

Hao Liu, Siyuan Yang, Qinglei Hu +1

Understanding why a spacecraft maneuvers -- rather than simply that it did -- is an increasingly important problem for space domain awareness as Earth orbits grow crowded and conte…
