Fine-tune will exceed the billing hard limit

Hey there. I have been trying to fine-tune davinci model on a large dataset of mine (app. 2 million words in the data) and facing an error of “fine-tune will exceed the billing hard limit”. However my estimate was only $80 or so while my account limit is $1200.
2 million words =~2.7 million tokens
2.7 million * $0.03/1000 = $80
Could anyone help me clarify the situation?
Thanks in advance!

Similar occurrence here. By my estimate, fine-tune should cost 1/3 of my hard cap.

yeah, I’m getting the same thing. Anyone have some answers?

Same error here,
And there is really very weak customer support open ai have on the internet
