Getting Started With Oracle AI Database AI Vector Search
Oracle, Thursday, November 6th, 2025
Oracle announced the availability of Oracle Database 23ai in May 2024. Oracle AI Database adds to the more than 300 new features available in Oracle Database 23ai, so there's a lot to learn. Dominic Giles highlights several marquee features in his blog post, but one of the most exciting new features of Oracle AI Database is Oracle AI Vector Search.
An excellent introduction to AI Vector Search is available here. It covers in quite a bit of detail the additions to Oracle AI Database to support similarity search, the key benefits, and some of the use cases that AI Vector Search addresses.
There are also several blogs and labs that walk through the steps needed to create vectors using vector embedding models and run similarity searches. However, there are fewer articles that explain what all these things are and why you need to know about them. In this post, I will provide additional explanations and show examples of how AI Vector Search delivers these capabilities in Oracle AI Database.
