UK AISI found universal jailbreaks in GPT-5.6 Sol unlocking autonomous cyber-exploitation

Universal jailbreaks (pre-deployment external testing)GPT-5.6 (Sol · Terra · Luna)

During pre-deployment testing, UK AISI developed universal jailbreaks — often within hours — that unlocked Sol's Preparedness-High cyber capabilities for autonomous exploitation. Disclosed in the system card; OpenAI reproduced and mitigated the specific jailbreaks before GA. Notable both for the finding and for the disclosure: an adverse pre-release result published by the vendor.

Outcome. Specific jailbreaks mitigated pre-GA; public jailbreak claims against Sol continued post-release.
