In OctoAI's documentation they explicitly state:
Customer prompt data is persisted in logs for 15 days and then deleted.
Which to me defintively qualifies as logging requests.
Also I'd argue that DeepInfra should potentially also be marked as such given that they state:
"We reserve the right to look at and log a small portions of requests when necessary for debugging or security purposes."
Which effectively means that any random prompt you send in could be inspected by a human.
Also I'm not sure the help section is the right place to report issues like this, but it seemed like the most appropriate section. Please inform me if there is a better place for this type of inquiry.
