SpatialOPSD: Self-Distilling Spatial Intelligence from Verified Coding Agent Traces

Rongxue Li, Meng Yang, Yiru Mao et al. · 2026

Spatial coding agents significantly improve spatial reasoning in Multimodal Large Language Models (MLLMs) by using external tools to generate verified execution traces. However, this paradigm inherently suffers from prohibitive inference-time overhead and external dependencies. In this paper, we explore whether an MLLM …

UniData: Universal Multimodal Instruction Generation Pipeline

Jiaqi Tang, Yi-Feng Wu, Yuting Zhang et al. · 2026

Multimodal Large Language Models (MLLMs) are increasingly being applied in a wider range of real-world scenarios. However, due to the substantial labor cost, creating high-quality multimodal instruction datasets for MLLMs remains a significant challenge. Although some methods propose to generate instruction data, they …
