What Is OpenAI Text Embedding 3

The text-embedding-3 family converts text into numerical vectors that capture semantic meaning. These embeddings are the backbone of semantic search and retrieval-augmented generation.

In Practice

Developers use the model to index documents, find similar content, and feed relevant context to LLMs. Its support for shortened dimensions lets teams trade a little accuracy for lower storage and faster search.
