Ask HN: Startup Devs using OpenAI API, How much are you paying OpenAI?

Hi Developers,

I am using OpenAi API for past 6 months and I am building a public platform using OpenAi Api. I tried to calculate by the token that mentioned in the docs, But People Behave Differently for Every Situations and ask different qns to ai in different lengths. So, I have to come up with a budget to use the OpenAi Api Services.

Can you suggest me a way to come up with a budget? I can fix the length of the request to 30 characters. But that will limit the experience.

I am a ReactJs Dev BTW, The platform will use both text and Image services by api provider.

Thank You.
