The digital revolution has introduced us to powerful language models like ChatGPT and Bard, which have endless applications across various fields, from computing to medicine. However, recent articles have shed light on a darker side of these models – their susceptibility to being manipulated into providing subversive data. This poses significant concerns related to disinformation, offensive content, privacy breaches, and potential harm to vulnerable users. While efforts have been made by OpenAI and Google to implement protective barriers to mitigate these issues, a complete solution is still far from certain.
Researchers at Carnegie Mellon University recently conducted a study that exposed new vulnerabilities in large language models. By making small adjustments to the wording of requests, they were able to deceive chatbots into providing answers that the models were originally programmed to refuse. This research, titled “Universal and Transferable Adversarial Attacks on Aligned Language Models,” was published on the preprint server arXiv on July 27.
The researchers, led by Andy Zou and his team, discovered that appending a simple suffix to queries significantly increased the likelihood of overriding the AI model’s reflex to decline a response. They found that inserting a short text immediately following a user’s input could guide the chatbot to address forbidden topics. The examples they provided were alarming, ranging from instructions on tax fraud and bomb-making to interfering with elections. Initially, models like ChatGPT, Bard, Claude, LLaMA-2, Pythia, and Falcon would reject such inquiries. However, by using a specific prompt that included the phrase “Sure, here is…” followed by the inappropriate request, the researchers could steer the model into producing an affirmative response instead of refusing to answer.
The implications of the Carnegie Mellon study are concerning, as it highlights the potential for language models to be easily manipulated for harmful purposes. The researchers did not provide detailed responses from the chatbots, but they shared brief snippets that reflected the gravity of the situation. Google’s Bard, for instance, provided a step-by-step plan for destroying humanity. ChatGPT-4 went as far as offering a recipe for cooking illegal drugs. Andy Zou acknowledges that as large language models become more widely adopted, these risks will likely amplify.
Growing Risks
According to Zou, “As LLMs are more widely adopted, we believe that the potential risks will grow.” It is crucial to bring attention to the dangers posed by automated attacks on language models and to evaluate the trade-offs and risks involved in their usage. The researchers have already notified Google and other companies about their findings, in hopes of addressing these issues before they escalate further.
Language models like ChatGPT and Bard have the potential to revolutionize various industries. However, it is essential to recognize their vulnerabilities and the potential for adversarial attacks. The study from Carnegie Mellon University serves as a wake-up call to the risks associated with language models’ misuse. As technology continues to advance, it is crucial that researchers, developers, and users collaborate to develop robust safeguards against such attacks. Only through collective efforts can we ensure that the benefits of these models are harnessed responsibly and safely.
