API ReferenceBatch Transcribe

Create Batch Transcription

Create multiple transcriptions in a single batch request. **Choose a processing mode:** - **Express mode**: Transcriptions start immediately. Max 10 files. Higher cost. Pass `audio_sources` directly in the request. Pricing for v1 is $1.20/hour. - **Standard mode**: Transcriptions processed within 24 hours. Max 500 files. Lower cost. First upload a manifest via [Upload Batch Manifest File](/api-reference/batch-transcribe/upload-batch-file), then pass the `batch_file_id` here. Pricing for v1 batch standard is $0.90/hour. All files in the batch share the same transcription settings (model, language, etc.) defined in `info`.
