      description: 'Check whether an image or audio file contains known OpenAI provenance signals. Learn more about content provenance.


        If `not_detected`, it means the tool did not find supported signals in the uploaded file. The content could still have been generated by OpenAI if the metadata was stripped or has evidence of tampering, the watermark was degraded, it comes from a legacy generation model, or it was created before provenance signals were available. Content could also still be AI-generated by another company''s model, which the tool currently does not detect.'

    description: 'When you [create a Response](https://developers.openai.com/api/reference/resources/responses/methods/create) with

      `stream` set to `true`, the server will emit server-sent events to the

      client as the Response is generated. This section contains the events that

      are emitted by the server.


      When processing a `compaction_trigger`, `response.compaction.compacting`

      reports newly sampled summary output at most once every 30 seconds. It

      carries no summary content and does not modify the compaction output item.

      The existing `response.output_item.added` and `response.output_item.done`

      events mark that item''s lifecycle; `response.output_item.done` carries its

      final encrypted content. A short compaction may finish without emitting a

      progress event.
