Penggunaan
Kompatibilitas model dan kasus penggunaan
Zvec stores and searches embeddings but the supplied repository material does not name compatible embedding models, LLM providers, or MCP integrations. Its RAG, agent-memory, and LLM-memory relevance comes from local dense, sparse, full-text, and hybrid retrieval rather than a stated dependency on a particular model.
