LEANN: RAG System with 97% Storage Savings for On-Device Private Retrieval

LEANN is an open-source retrieval-augmented generation (RAG) system targeting personal device deployment with claimed 97% storage reduction compared to conventional vector index approaches. The project is associated with MLsys 2026, suggesting an upcoming systems research paper. It emphasizes privacy through fully local execution and aims to maintain retrieval accuracy despite aggressive compression. The repository has accumulated over 11,000 stars with strong recent momentum.
