What are LLMWare and R2R?

LLMWare

LLMWare is an open-source framework for building retrieval-augmented generation pipelines optimized for small, specialized language models. It provides document parsing, embeddings, and model management for fully self-hosted deployments.

  • Small model optimized
  • Document parsing pipeline
  • Embedded vector storage
  • Model catalog

R2R

R2R (RAG to Riches) is a retrieval-augmented generation engine that bundles ingestion, hybrid search, knowledge graphs, and agentic reasoning behind a single API. It is designed for self-hosted production deployment of document question answering.

  • Hybrid and graph search
  • Document ingestion pipeline
  • Agentic RAG endpoints
  • User and collection management
