Researchers have introduced a new diagnostic framework for graph foundation models using graph invariants. This approach aims to disentangle the impact of node features from graph structure in benchmark evaluations. The proposed invariant-based models demonstrate competitiveness with, and sometimes superiority over, existing transformer and message-passing baselines across 26 datasets, suggesting that structural proxies can be as effective as trained models for certain tasks.
