Hi there, yes, it looks like you used up the allocation of free tokens associated with your account. It’s usually more than enough for a few trial prototypes, but I think in your case, you had a data set of 6500 workitems and ran through all of it a few times, so that maxed you out.
I’ve sent you an email – we’d like to better understand your usage scenario and how we can best help. We’d be glad to try.
You can also unblock your account by putting in your own OpenAI API key, but we don’t want you to be burning tokens unnecessarily either. So ideally, let’s talk first. Thanks
