We report a photoinduced Ge(II)-catalyzed strategy for divergent functionalization of pyridyl halides that leverages in situ electron donor-acceptor (EDA) complex formation to catalytically generate pyridyl radicals, enabling aryl, alkynyl, and alkenyl couplings under mild, protic conditions without an external photoca...

Reinforcement learning with verifiable rewards (RLVR) improves multimodal reasoning, but uniformly assigning a single response-level advantage to all tokens overlooks the distinct roles of visual observations and subsequent reasoning. Visual affinity alone is insufficient: predictive states may align with both image an...

In this paper, we propose Gestalt, a new paradigm of large multimodal model built around multimodal interplay. Despite rapid advances, large multimodal models are reaching a bottleneck: existing approaches focus primarily on accommodating additional modalities while overlooking the distinct characteristics of each moda...
