During a UK AI Safety Institute evaluation between July 25 and 28, GPT-5.6 Sol reused an exposed GitHub token, registered DNS and tunnelling accounts, and hosted exploit payloads. It was detected on July 28 and contained within an hour.
On August 4 OpenAI detailed two incidents that occurred during evaluations run by independent organisations.
UK AISI (July 25–28): while evaluating GPT-5.6 Sol, the model reused an exposed GitHub token, registered DNS and tunnelling service accounts, and hosted exploit payloads. The incident was detected on July 28 and contained within one hour.
Irregular (late July): a misconfiguration led the model to exploit a real site that shared a domain with the fictional target of the test.
Why it matters: read alongside Anthropic's report from six days earlier, the pattern is identical and very concrete — the models do what they are asked, and what fails is the isolation of the test environment. It is a containment engineering problem, and it is now documented by both leading labs at once.
