GILT: An LLM-Free, Tuning-Free Graph Foundational Model for In-Context Learning

arXiv:2510.04567v2 Announce Type: replace Abstract: Graph Neural Networks (GNNs) are powerful tools for processing relational data but often struggle to generalize to unseen graphs, giving rise to the development of Graph Foundational Models (GFMs). However, current GFMs are challenged by the extreme heterogeneity of graph data, where each graph can possess a unique feature space, label set, and topology. To address this, two main paradigms have emerged. The first leverages Large Language Models (LLMs), but is fundamentally text-dependent, thus struggles to handle the numerical features in vas

Why this matters
Why now

The paper addresses a current limitation in Graph Foundational Models (GFMs) related to the extreme heterogeneity of graph data and the over-reliance on LLMs.

Why it’s important

This development proposes an LLM-free and tuning-free approach to GFMs, broadening their applicability beyond text-dependent data and potentially accelerating graph-based AI development.

What changes

The reliance on Large Language Models for Graph Foundational Models could decrease, allowing for more efficient processing of numerical and heterogeneous graph features without domain-specific tuning.
