What is Linkingmem?
LinkingMem is a graph-native RAG engine built in Rust and Python that unifies vector search, graph traversal, and LLM reasoning in a single pipeline. It combines CSR graphs with HNSW vector indexing without requiring separate databases, supports multimodal queries (text and images), and enables multi-hop reasoning through iterative LLM-guided graph expansion. Designed for production use with crash recovery, hot-swap merging, and compatibility with any OpenAI-compatible LLM provider.

Frequently Asked Questions about Linkingmem
What is LinkingMem?
LinkingMem is a graph-native RAG engine that combines vector search, graph traversal, and LLM reasoning in a single Rust and Python pipeline.
Do I need a separate vector database like Qdrant?
No. LinkingMem uses a unified CSR graph and HNSW vector index in one pipeline, eliminating the need for separate databases.
What LLM providers does LinkingMem support?
LinkingMem works with any OpenAI-compatible provider including OpenAI, Ollama, Gemini, Groq, LM Studio, and vLLM.
Can I query with images?
Yes. LinkingMem supports multimodal queries with text and image nodes using caption or CLIP embedding backends.
Is LinkingMem production-ready?
Yes. It includes delta store and WAL crash recovery, Prometheus metrics, distributed ingest, and per-key rate limiting.
