Qdrant (read: quadrant) is a container-based vector similarity search engine and vector database.

---

We use Qdrant as the standard vector database of our GenAI stack. The Dienstleistungsfinder KI-Suche relies on its hybrid search that combines BM25 keyword search with semantic embeddings, and Zammad-AI performs retrieval over knowledge bases with LangChain and Qdrant. Recommendations similar to the saved titles of the Bibliotheks-Pods are also served from Qdrant.
