multi-hop-rag

Presents a training-free method for multi-hop retrieval-augmented generation that avoids costly graph rebuilds when underlying data changes, tackling the staleness issue in dynamic environments.

MOTHRAG is a multi-hop RAG system that matches the performance of top GPU-dependent systems (HippoRAG 2, CoRAG, NeocorRAG) using only commodity API calls, with no GPU, no fine-tuning, and deployment via pip install plus API keys.
