HuggingGraph, the first work to systematically collect the LLM supply chain information and analyze it at scale.

• 📦 Systematically collect LLM supply chain data – We curate large-scale metadata connecting models and datasets across the LLM ecosystem.
• 🔗 Construct an LLM supply chain graph – We build a directed, heterogeneous graph that captures relationships between base models, fine-tuned models, adapters, quantized/merged variants, and datasets.
• 🔍 Perform rich graph analytics – We conduct forward and backward analyses to trace lineage, uncover dependencies, and derive insights into risks and evolution in the LLM supply chain.
