Update timeline

  1. investigating Aug 18, 2026, 07:34 PM UTC

    We're currently seeing longer than usual processing times for asynchronous transcription requests using Universal-3 Pro and Universal-3.5 Pro. Requests are being accepted and are completing, but time to completion is elevated while our queues work through a backlog.

  2. identified Aug 18, 2026, 07:46 PM UTC

    We have identified the cause of the elevated processing times affecting pre-recorded transcription requests using Universal-3 Pro and Universal-3.5 Pro. Our engineering team has addressed a capacity constraint and is working to restore full capacity. Processing times will remain elevated while the backlog clears, and some customers may see requests queued or throttled. We will continue to provide updates as more information becomes available.

    Processing times for pre-recorded transcription requests using Universal-3 Pro and Universal-3.5 Pro are returning to normal ranges and the backlog has largely cleared. We are continuing to monitor to ensure stability.
