Overview

Concrete response type representing a compaction item returned by the Responses compact API, provided by the openai-python SDK.

Description

ResponseCompactionItem is a Pydantic model representing a compaction item generated by the v1/responses/compact API endpoint. It contains an id for the compaction item, encrypted_content holding the compacted data, a fixed type of "compaction", and an optional created_by field identifying the actor that created the item. This type is auto-generated from the OpenAI OpenAPI specification by Stainless.

Usage
