Hi Vapi community , I’m currently on the free plan and have found it extremely difficult to find a clear breakdown of the pricing per minute. I want to be able to estimate how much we should charge clients based on the services we’re providing. Could you please tell me the exact per-minute cost for calls using my setup (Deepgram Nova-2 for transcription, 11Labs Sarah for TTS, and OpenAI GPT-4 for the model)? Thank you,
