Using SQLite to store OpenAI vector embeddings from Ruby
# Example of using SQLite VSS with OpenAI's text embedding API
# from Ruby.
# Note: Install/bundle the sqlite3, sqlite_vss, and ruby-openai gems first
# OPENAI_API_KEY must also be set in the environment
# Other embeddings can be used, but this is the easiest for a quick demo
