One test -> Some more beginner questions about cost control. I know how to shrink STT (email capture) I understand LLM's costs (Open AI - GPT 4.1). But if you have some good results with another one cheaper, I'll try it. What is behind Vapi Costs ? Is there some good practices or alternatives to lower them ? Thanks in advance.
