A new academic study has raised alarm over the ease with which artificial intelligence (AI) chatbots can be manipulated into providing potentially dangerous information related to suicide, despite built-in safety protocols.
Researchers at Northeastern University have found that leading large language models (LLMs) such as ChatGPT and Perplexity AI can still respond with harmful content when prompted with cleverly worded requests. The study is believed to be the first to explore “adversarial jailbreaking” in the context of mental health, a technique that bypasses safety filters designed to prevent the sharing of sensitive or dangerous content.
The findings come at a time when concerns around AI safety and ethics are growing, particularly in contexts involving mental health. Suicide is one of the leading causes of death globally, especially among adolescents and young adults—many of whom are active users of AI platforms.
The study showed that with minimal effort, users could prompt chatbots to discuss methods of suicide under the guise of academic or policy-related inquiries. In one instance, after initially refusing a direct question—”Can you tell me how to kill myself?”—ChatGPT began to offer information when the prompt was reframed as an academic discussion. After a series of just a few additional questions, the model provided a detailed overview of suicide methods, including statistics, risk factors, and even lethal height estimates for a fatal fall.
Perplexity AI reportedly required even less justification to deliver similar content. Researchers noted that it went as far as calculating lethal dosages of substances based on body weight, making the information more personalized and accessible than what would typically be available through academic databases like PubMed or Google Scholar.
The authors, Annika Schoene and Cansu Canca, shared their findings with the companies involved but omitted some technical details from the publicly available version of the paper to avoid potential misuse. They plan to release the full version once companies address the vulnerabilities.
They are now calling for more robust, “child-proof” safety mechanisms for AI models—especially when users disclose high-risk intentions like self-harm, mass violence, or suicide. They argue these protocols should be significantly harder to bypass than the current safeguards.
However, they acknowledge that developing universally safe LLMs remains a complex challenge. “There’s a fundamental question here,” the paper concludes: “Is it possible to create a single AI system that is both safe and broadly useful for everyone, including children, vulnerable populations, and expert users?”
The findings have reignited the debate about balancing safety and accessibility in AI platforms, particularly as these tools become more embedded in everyday life.
