Thank you for your response and concerns.
Regarding the excessive billing, my suspicion arises from the simultaneous surge in API Vision requests. I’ve observed instances where 500 API Vision requests occur within a single minute, which significantly inflates the billing. While I understand that GPT-4 Vision requests can accrue costs rapidly, the sudden spike seems disproportionate to the actual usage of the application.
To address your point about API key security, I’ve taken measures to ensure its protection. However, I would appreciate any guidance or best practices you could offer to further enhance the security of the API key.
Thank you for your assistance.
