I managed to manually produce this bug 2 months ago.
As they don't have any bug bounty, I didn't submitted it.
By starting a conversation and refreshing before ChatGPT has time to answer, I managed to reproduce this bug 2-3 times in January.
I find even it funny now, they could write that they will provide free API creds, but now they had a very bad moment due to their greed.
Missed a word.
I dunno, I generally report issues I find in software, paid or not, as I've always done. Takes usually ~10 minutes and 1% of the time, they ask for more details and I spend maybe 20 minutes more to fill out some more details.
Never been paid for it ever, most I gotten was a free yearly subscription. But in general I do it because I want what I use to be less buggy.
