The framework outperforms existing LLM-as-predictor methods (GraphGPT, LLaGA) on unseen citation and e-commerce datasets for both node classification and link prediction, achieving 0.848 accuracy on Pubmed (vs. 0.793 for LLaGA) and 0.689 AUC on Pubmed link prediction (vs. 0.569 for LLaGA). Ablation studies show both feature-wise contrastive learning and graph token embeddings are essential for cross-task transfer, with the feature-wise constraint particularly important for unseen tasks.",
