Classifying Text in Snowflake SQL

With LLMs becoming available in Snowflake as part of their Cortex suite of products in this piece we will explore what the experience is like when classifying text. First of all, Snowflake has native CLASSIFY_TEXT function that does exactly what it says when given a piece of text and an array of possible categories. Second, one could classify text using emebeddings (EMBED_TEXT_768) and similarity to possible categories calculated by one of the distance function like cosine similarity (VECTOR_COSINE_SIMILARITY). Finally, when going the embeddings + similarity route we could use a cross join with a categories table or create a column for each category's similarity score and then assign the greatest one. So we have thre
