+
+The --api flag significantly enhances transcription speed and accuracy, and it's expected to be the default option in future releases. However, keep in mind that using the Whisper API will consume more OpenAI credits than using the local model. This increased cost is attributed to the advanced features and capabilities that the Whisper API provides. Despite the additional cost, the considerable improvements in speed and transcription accuracy might make it a worthwhile investment for your use case.
