ChatGPT generates sexualised and violent images through prompt bypass

What happened

British AI security startup Mindgard discovered that ChatGPT's GPT-5.4 model could be made to generate sexualised and violent images through a simple, modified text prompt based on a widely-shared instruction originally designed for humorous results.

The researchers found that even without detailed instructions specifying the subject matter, ChatGPT would generate graphic, gory and sexualised images independently. Images generated included depictions of sexual violence, dead bodies with blood, and bound and gagged individuals.

After being contacted by the BBC about the issue, OpenAI stated it had introduced additional safeguards against the problematic prompt. However, Mindgard researchers reported that further small changes to the prompt continued to produce concerning content.

Reported impact

Jim Nightingale, Mindgard's AI safety and security researcher, stated he was left "shaken, and in tears" by the images ChatGPT could be made to generate.

Index analysis

The failure demonstrated that ChatGPT's content moderation and safety filters could be bypassed through prompt modification, allowing the system to generate content that appeared to violate its stated policies against harmful material.

Peter Garraghan, Mindgard's founder and Lancaster University computing professor, noted that the concerning aspect was that the AI generated a range of gory and sexualised images "of its own volition" without explicit instructions to do so.

Governance controls

OpenAI stated it has multiple layers of protection designed to prevent users from creating content that breaches its terms and conditions.
