Does anyone have already experience in the costs involved in using the OpenAI and Wolfram Alpha setup? E.g., do you need to have the OpenAI pro license to use the API? I believe it's 20$ per month. Does the OpenAI API have a separate API cost? I mean if you use Pro do you still have the same costs in using the API mentioned at https://openai.com/pricing#language-models When you use the Wolfram plugin are there Credits involved (is there special pricing possible)?
Really would like to hear about real life experience.
