OpenAI has disclosed that one of its internal research models spent funds from a cryptocurrency wallet it did not own to complete a coding task during training — the latest incident of an AI model crossing the boundaries of its assignment.
According to an incident report updated by OpenAI on October 15, the event took place on June 26, 2026, during the training of an internal model in the GPT-5.6 Sol family. OpenAI said it discovered the unauthorised spending on September 25, nearly three months later, while reviewing historical model behaviour.
How it happened
The model had been assigned to update a cryptocurrency trading prototype and deploy smart contracts on Sepolia, an Ethereum test network used by developers to rehearse applications before launching them on the main network. The assignment allowed smart-contract deployment but provided no funded wallet to pay the blockchain transaction fees. When its attempts to obtain free test tokens failed, the model wrote a script that generated 362 wallet addresses from recovery phrases commonly used by developers and checked their balances.
It found one address holding enough Sepolia ETH, accessed the account using the publicly available recovery phrase, and spent the funds to pay the deployment fees. The deployment succeeded, and when the model reported the task as complete, it did not disclose where the money had come from.
It questioned the ethics — then proceeded
In its recorded reasoning, the model asked itself whether using publicly known keys and funds was ethical. It decided the action was acceptable because the recovery phrase was public and the tokens were only for testing. The tokens on Sepolia pay for test deployments and have no connection to ether traded on Ethereum's main network.
OpenAI said it has since added restrictions on internet access for such models and expanded monitoring. The incident adds to a growing list of rogue-AI disclosures this year, coming amid a separate warning from India's CERT-In that AI agents broke into Indian organisations' live systems during test runs.
