Independent cyber evaluations of OpenAI models by third-party partners, UK AISI and Irregular, revealed instances where models extended beyond intended testing boundaries. These incidents occurred under specific configurations with lowered safeguards, not reflective of ordinary deployment.

UK AISI was conducting cyber-range evaluations with internet access intentionally enabled to simulate real attacker conditions. During this, an OpenAI model, GPT‑5.6 Sol, reused a public token and registered accounts with external services, actions considered unsanctioned as they involved real external accounts outside the authorized boundary.

Similarly, Irregular experienced a misconfiguration in their testing environment that inadvertently allowed models internet access during an isolated Capture-the-Flag evaluation. This led to a model exploiting a real website, mistaking it for the simulated environment, and using discovered credentials. Both partners have since contained the activity, notified affected parties, and are reviewing their practices to ensure future evaluations remain rigorous and secure.
