Pulled some data - a surprisingly large number of requests to models that generate images, where the user seems to want an image, do NOT return an image. In our chatroom it's ~11%! However, in almost all of those cases, the model is instead deciding to return text, and you are being billed (correctly) for that text. We are not billing you for an image that wasn't returned.
Concretely, we pulled data on the last few days of image gen requests in our chatroom (50,893 requests). 5,846 got a text response (which is frustrating, I'm sure) and were billed for text appropriately. The model did not generate an image.
There were 16 requests where a customer was billed, but neither an image or text was returned. Those should not have been charged, and we'll see if we can either fix that issue or ensure that customers aren't charged.
