Is Whisper API really 10x more expensive than self hosted?

To transcribe 1 hour of audio with OpenAI, it would cost you: $0.36, taking you 2 minutes. Whereas… To transcribe 1 hour of audio with self-hosted whisper, it would cost you 2 minute of run-time (1/30th of $0.39h, so basically 1.333 cents, or $0.013), taking you 2 minutes. That’s a 30x cost difference. You are incorrect when you state that they’re both 1 to 1. They both take the same amount of time, but self-hosted is effectively 30x less expensive.
