  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.
