May 16, 2024 — Vector data type and vector similarity functions — General Availability¶

With this release, we are pleased to announce the general availability of VECTOR data type, vector similarity functions, and the vector embedding function. These features enable important applications that require semantic vector search and retrieval.

For more information, see Vector Embeddings.

New SQL data type¶

The following data type is now generally available with this release:

Category	New data type	Description
Vector	VECTOR	With the VECTOR data type, Snowflake encodes and processes vectors efficiently. This data type supports semantic vector search and retrieval applications, such as RAG-based applications, and common operations on vectors in vector-processing applications.

New SQL functions¶

The following functions are now generally available with this release:

Function Category	New Function	Description
Vector Similarity Function	VECTOR_INNER_PRODUCT	Returns the inner product of two vectors. The inner product (also known as the dot or scalar product) multiplies two vectors
Vector Similarity Function	VECTOR_L2_DISTANCE	Measures the L2 distance between two vectors.
Vector Similarity Function	VECTOR_COSINE_SIMILARITY	Measures the cosine similarity between two vectors, which is the angular distance between the vectors in a multi-dimensional space.
LLM Function	EMBED_TEXT_768 (SNOWFLAKE.CORTEX)	Creates a vector embedding for a given string of text in English.
