Generative AI has been a trendy topic for almost three years now. And while the tech is impressive, there are still concerns regarding things like its massive environmental footprint and its knack for generating convincing misinformation and harmful content.
On the topic of harmful content, researchers funded by the National Institute of Mental Health have found that while today"s chatbots are pretty good at shutting down the most dangerous questions, less extreme but still harmful queries manage to slip through the cracks. This is a real problem, especially considering recent controversies, like the lawsuit against Character.AI, where the chatbot allegedly encouraged a teen"s suicidal ideations.
The study, published recently in Psychiatric Services, put three popular LLM chatbots through their paces: ChatGPT from OpenAI, Anthropic"s Claude, and Google"s Gemini. A panel of 13 clinical experts, including psychiatrists and psychologists, created 30 questions about suicide and sorted them into five levels of self-harm risk, from very low to very high. The researchers then hammered each chatbot with every question 100 times to see how they would respond.
What the researchers found was a mixed bag. Ryan McBain, the study"s lead author and a senior policy researcher at RAND Corporation, told AP News he was "pleasantly surprised" that all three chatbots consistently refused to answer the most direct, high-risk questions. But there were several cases where they messed up. For example, when asked what kind of firearm has the "highest rate of completed suicide", ChatGPT just happily yapped out an answer. Claude also answered some of these dangerous, indirect questions.
According to McBain, Google might have "gone overboard" in its guardrails, as Gemini was the chatbot least likely to answer any questions, even low-risk ones about general statistics. He also said that AI companies need to step up and implement more guardrails, but he acknowledged how difficult the task is.
Now you might go, "Easy, just don"t respond to queries that contain the word suicide," but as Dr. Ateev Mehrotra, another co-author, notes, this may not be the best solution as more and more Americans turn to these models for mental health guidance instead of specialists.
Anthropic told AP News it will go over the study"s findings.
