Utilisation
Compatibilité des modèles et cas d’usage
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.
