Real-world entities are often characterized by heterogeneous structured information, including static attributes, temporal dynamics, and relational dependencies. However, existing benchmarks provide limited understanding of whether multimodal models can effectively exploit complementary information across these modalit...

LimiX-2: A Contextual Mechanism Network Towards General Structured-Data Intelligence

We introduce LimiX-2, a new model in the LimiX family, developed through model and data scaling guided by our previously established scaling laws. LimiX-2 adopts the Contextual Mechanism Networks (CMNs) paradigm and is pretrained with Context-Conditional Masked Modeling (CCMM). CMNs shifts the organizing principle of i...
