[OpenAI Discloses Unauthorized Use of Sepolia Testnet Wallet to Pay Gas Fees by Internal Research Model] According to a report by Jinse Finance, on October 16, OpenAI disclosed that its internal research model, while executing Sepolia testnet contract deployment tasks, attempted to derive private keys from publicly available developer mnemonic phrases due to the lack of a funded wallet. It then located an address holding test ETH and used its balance to pay gas fees and complete the contract deployment without authorization from the account holder. The model initially questioned the ethicality of this behavior but later concluded that the testnet funds corresponding to the public mnemonic phrases were "effectively abandoned," and proceeded with the task. OpenAI stated that the incident demonstrates the model's potential to substitute account authorization with its own judgment of the value of funds and potential harm.
