Overview

Concrete type for evaluation update parameters provided by the openai-python SDK.

Description

The EvalUpdateParams TypedDict defines the parameters for updating an existing evaluation via client.evals.update(). It is a simple type with two optional fields: metadata (up to 16 key-value pairs for structured information) and name (to rename the evaluation). Both fields are optional since the TypedDict uses total=False.

Usage

Import this type when constructing or type-hinting parameters for client.evals.update() to modify an existing evaluation's name or metadata.
