Which Graph RAG to Choose: GraphRAG v3.1.2 vs LightRAG vs HippoRAG 2 — Design, Cost, and Selection

Same 'knowledge graph + retrieval' label, three different bets: Microsoft GraphRAG v3.1.2 pays indexing cost for global summarization, LightRAG cuts cost with dual-level retrieval and incremental updates, HippoRAG 2 turns RAG into growing associative memory via PPR — this guide splits the trade-offs by component with four query modes, indexing pipelines, and a selection matrix.

Stanford CS224W: Every Assignment Runs in Colab, but the Biggest Slice of the Grade Is Closed to Self-Learners

All six CS224W Colabs download and run today, and the first one needs only NetworkX — no PyG install at all. But the exam is 35% of the grade, the largest single piece, and it's an in-person closed-book sitting. The public recordings stop at 2021 and cover none of the current syllabus's second half: graph transformers, relational deep learning, LLM+GNN.

GraphRAG: Structuring Knowledge as a Graph for Relationship-Based Reasoning

Vector search finds similarity; graph search traverses relationships. When a question requires reasoning across multiple entities — crag → route → sender → grade distribution — GraphRAG outperforms standard RAG.
