It's saying there is no such organization, but the organization ID looks ok to me. If that's the same key as you get in https://platform.openai.com/account/org-settings, I don't know why OpenAI is complaining. Actually the organization ID is not really required by the API, it's just if someone has several organizations registered with OpenAI. In the next version, I will drop the organization ID requirement from the config. Until then, double check whether the ID shown on OpenAI's web page is really the same as in your config file.
Update: the new version is out; you don't need to enter the OpenAI organization ID anymore.
dude, when I just set up everything with my API keys and Organization ID on OpenAI at config.txt, and then I clicked "Save" button at the tab in Notepad.
