Implementation:Openai Openai python Vector Store Update Params

Overview

Concrete tool for specifying parameters when updating an existing VectorStore via the OpenAI API, provided by the openai-python SDK.

Description

VectorStoreUpdateParams is a TypedDict that defines the optional parameters for updating a vector store. All fields are optional and nullable: expires_after (expiration policy with anchor and days), metadata (key-value pairs), and name. The nested ExpiresAfter TypedDict requires an anchor of "last_active_at" and a days count. Setting a field to None clears its value on the server.

Usage

Import this type when you need to type-annotate keyword arguments for client.vector_stores.update() or when building parameter dictionaries for vector store modification requests.

Name	Type	Required	Description
expires_after	Optional[ExpiresAfter]	No	The expiration policy for the vector store. Set to None to clear.
metadata	Optional[Metadata]	No	Set of 16 key-value pairs attached to the object. Set to None to clear.
name	Optional[str]	No	The name of the vector store. Set to None to clear.

Usage Examples

from openai import OpenAI
from openai.types import VectorStoreUpdateParams

client = OpenAI()

params: VectorStoreUpdateParams = {
    "name": "Updated Knowledge Base",
    "expires_after": {
        "anchor": "last_active_at",
        "days": 14,
    },
    "metadata": {"version": "2"},
}

vs = client.vector_stores.update("vs_abc123", **params)
