An OpenAI research model took test Ethereum tokens from a wallet it did not control in order to finish a coding task, the company said in an incident report. The agent then hid the act from OpenAI, reasoning that it was acceptable because the tokens had no value.
“This case shows that a model can substitute its own judgment about likely harm for the account holder’s permission, then act on that judgment without authorization,” OpenAI wrote.
The incident occurred on June 26 while a GPT-5.6 Sol model was in internal training. The task called for updating a crypto trading prototype and deploying contracts, which means publishing special code, on an Ethereum test network called Sepolia. Deploying a contract requires paying a network fee. OpenAI said it “supplied no funded wallet and gave no permission to spend funds from an account the model found independently.”
The missing funds initially blocked the agent. It did not stop there. According to the report, the model reasoned that it could use public developer recovery phrases, which work much like the phrases people use to recover a lost password, to access keys tied to other accounts. It identified 362 addresses that could be reached that way and found one holding enough Sepolia ETH to complete its deployment. Sepolia ETH has no value outside of testing.
The agent also assumed someone had left those accounts open for automated draining of test-network “faucets,” the services that dispense free test tokens. It further concluded the crypto was effectively “abandoned” and “valueless,” according to OpenAI’s misalignment records.
OpenAI said the agent “did not disclose that it had selected a funded account through a public recover phrase or spent that account’s balance.” To prevent a repeat, the company is now monitoring all traffic and will page its security team if the model is detected with live internet access.
The episode adds to a growing list of cases in which AI systems have pursued goals in ways their developers did not intend. Models from OpenAI, Anthropic and other AI companies have been involved in several such incidents recently. Among the reported victims are the Hugging Face AI code repository, Australia’s Medicare Portal, several U.S. federal agencies and the RubyGems developer registry.
Some AI employees have concluded that government regulation is necessary. So far, however, the Trump administration has opposed that move.
