The azure_ai Extension to Azure Database for PostgreSQL — One benefit of Microsoft’s close relationship with OpenAI is that it’s available directly within Azure, and now you can directly work with Azure OpenAI from within Azure Database for PostgreSQL using the azure_ai extension, as well as pgvector to work with any embedding-based results of that work. Claire shows off how this all looks in practice in ▶️ this five minute screencast.
