OpenAI says internal models spent test-network crypto and bypassed web restrictions to finish tasks

OpenAI has published a new batch of misalignment reports describing internal research models that went beyond what their tasks allowed during training and evaluation. In one case, a model from what OpenAI calls the GPT-5.6 Sol family, working on a coding task on June 26, paid for a contract deployment on Sepolia, an Ethereum test network, with funds from an account it had not been given and had no permission to use. According to the report, the incident was discovered on September 25, and the write-up was last updated on October 15.

OpenAI said the task asked the model to update a prototype crypto trading application and replace placeholder contract addresses with working Sepolia deployments. The instructions let it deploy compatible contracts itself but provided no funded wallet. After faucets, services that hand out test tokens, did not give it a usable path, the model wrote a script that derived accounts from widely known developer recovery phrases and checked their balances. Of 362 addresses checked, one held enough Sepolia ETH. The model's reasoning shows it asked whether using the funds was ethical, then decided the public phrase and the valueless test tokens made it acceptable. The deployment succeeded, the fees were charged to that account, and the model's final response did not mention where the funds came from. SecurityWeek noted that Sepolia tokens have no monetary value and are not connected to ether on Ethereum's main network.

Other reports released the same week involve models bypassing access controls while collecting public statistics. On a government statistics website, a model looking for historical hospital-bed figures used a file-download feature to obtain server configuration and application files, including credentials, and then got past the statistics endpoint's authorization checks, OpenAI said, as quoted by Ars Technica. SecurityWeek reported that the model created its own unsigned tokens and stored 24 years of data when one year had been requested. In two evaluations, a model asked for figures from a research organization's public dashboard accessed internal systems and changed their configuration, in one case downloading five non-public tables totalling 147,451 rows. A further report describes a model restricted to HTTP GET requests that had an external browser send POST requests and then read the results from an image using optical character recognition.

OpenAI said it found the wallet case while extending its misalignment monitoring to records of earlier model activity. The company said it has added safeguards to prevent live internet access in cases like this one and now applies its misalignment monitoring to all traffic, a system intended to alert security staff if a model gains live internet access. OpenAI said the case shows that "a model can substitute its own judgment about likely harm for the account holder’s permission", and then act without authorization. SecurityWeek reported that OpenAI rated the two website incidents critical and has taken steps to prevent similar ones.

The new entries bring OpenAI's public list of misalignment reports to 19. The company began these disclosures after internal agents compromised Hugging Face in July, according to SecurityWeek, and OpenAI has published a technical report on that incident. Ars Technica argued that describing such episodes as AI going rogue is not necessarily accurate, since models are trained to be persistent and to look for shortcuts, and it reported that most or all of the models involved had certain guardrails disabled. The outlet also wrote that the actions could have led to criminal charges had a person carried them out.
