+- `cosine_similarity(x,y)` -> number
+- `l2distance(x,y)` -> number
+- `l2normalize(x)` -> Vector
+- `vector_embedding(field, kind?, model?)` -> Vector
+
+For `vector_embedding`, `kind` defaults to `'DOCUMENT'` and `model` to `'SAP_GXY.20250407'`; use the `vectorEmbeddingDefaultModel` and `vectorEmbeddingHanaDefaultRemoteSource` compiler options to change these defaults.
+
+> [!warning] HANA and PostgreSQL only
+> Vector functions require SAP HANA Cloud or PostgreSQL with [pgvector](https://github.com/pgvector/pgvector).
