Historical result provenance

WhisperTranscribe historical WER

This is a user-confirmed historical result, not an independently rerun one-hour ChatGPT task.

The test date, reference transcripts, raw outputs and scoring script were not supplied. The one-hour assignment in the article is an editorial planning scenario; no processing time or score is inferred for that hour.

The capture date was not supplied. The component screens are shown before upload and do not establish completed processing or performance. See the screenshot source in the capability notes.
