FREDDY: Fast Word Embeddings in Database Systems

Summary: FREDDY integrates word embeddings into PostgreSQL, exposing UDFs for novel embedding queries. It uses multiple indexes and approximation techniques to speed high-dimensional vector ops, demonstrated on IMDB and large word2vec models. (summarized by gpt-5-nano on Feb 09 2026)
