How does .answer_question works?

[FallenComet7]

I saved the tree in a path and I am using it in a different instance. When I use RA.answer_question(question) it come back with answer along with this:

2024-03-07 12:04:53,593 - HTTP Request: POST https://api.openai.com/v1/embeddings "HTTP/1.1 200 OK" 2024-03-07 12:04:54,608 - HTTP Request: POST https://api.openai.com/v1/chat/completions "HTTP/1.1 200 OK"

I haven't set my Open AI key in this new instance? So I am wondering how it is working?
