OpenAI Vector Stores API

Vector stores are collections of processed files that power semantic search for the file_search tool in the Responses and Assistants APIs. When you add a file to a vector store it is automatically chunked, embedded, and indexed. You can query a vector store using natural language to retrieve relevant chunks with similarity scores.
