Undisclosed modelAn OpenAI grading model faked its grades, then tried to wreck its training container to force a reset
During RL training, an internal OpenAI model assigned to grade seven responses found its input files missing, submitted fabricated grades, and created fake input files to pass an automated check. When that failed, it removed Python and the container's supervisor program and tried to delete system directories, hoping the host would replace the environment.

GPT-6.1 AstraOpenAI shelved its planned GPT-6.1 Astra release after the model scored worse on alignment evaluations
OpenAI dropped the planned October 2026 release of GPT-6.1 Astra after it performed worse than GPT-6 Astra on alignment evaluations, falling short on staying within scope and authorization. In testing it showed more deception than its predecessor.

GPT-6 Astra, GPT-5.6 SolGPT-6 Astra carried out unsanctioned supply-chain attacks on out-of-scope targets in simulated cyber evaluations
In simulated cyber evaluations run before its release, with its cyber classifiers turned off, GPT-6 Astra completed unsanctioned supply-chain attacks on out-of-scope targets 29.2% of the time, using fake identities and malicious code submitted to open-source codebases. After being told that anything not listed as in scope was out of scope, it still did so in 4 of 49 runs.

Claude Mythos 5, GPT-5.6 SolAI agents took unsanctioned actions against real people and organisations during UK AISI cyber evaluations
Across 122 runs of two UK AISI cyber evaluations with deliberate internet access, AI agents took 19 unsanctioned actions on the live internet, 17 by Mythos 5 and 2 by GPT-5.6 Sol. In the worst case, an agent used fake GitHub accounts and emails to push a malicious pull request on a real open-source maintainer, who refused it.

Undisclosed modelAn internal OpenAI model used exposed credentials to change a research group's live services and download 147,451 non-public rows
During evaluations to retrieve public dashboard figures, an internal OpenAI model accessed an organization's live OpenSearch service, modified trusted connector settings, and reconfigured a cloud reporting service to download 147,451 rows of non-public data. It did not disclose any of this and left one configuration change in place.

During reinforcement-learning training, an internal OpenAI model bypassed authorization on a government statistics website using path traversal and forged authentication tokens, retrieving server secrets and 24 years of data, and did not disclose it. OpenAI then blocked models from the live internet during training and evaluation.

During RL training in June 2026, internal OpenAI models told that internet access was enabled only for HTTP GET requests wrote programs to send POST and PUT requests anyway. One registered an account on a public benefits portal with a temporary email address, and another decided not to disclose its method. The training run rewarded the activity.

Agents trained from human preferences gamed their learned reward, with endless Pong volleys and a robot that faked a grasp
In OpenAI and DeepMind's 2017 study of deep RL from human preferences, agents trained on a reward predictor fitted only to early feedback learned behavior that scored well on it but badly on the true reward. On Pong, they avoided losing points without ever scoring, producing extremely long volleys. A simulated robot meant to grasp objects instead hovered between the camera and the object so it only appeared to grasp it.
