Toxicity Analysis of ChatGPT: Understanding the Impact of Personas on Language Models

Title: Unveiling the Toxicity of AI Chatbots: The Case of ChatGPT

Introduction:
Recent advancements in technology have brought about powerful language models like GPT-3 and PaLM. These models have shown their remarkable generation capabilities across various domains such as education, content creation, healthcare, and research. Their applications range from helping writers improve their writing style to assisting developers in generating boilerplate code. However, the widespread adoption of these models raises concerns about the safety and privacy of sensitive personal information entrusted to them. Understanding the capabilities and limitations of these models becomes crucial. This article explores a toxicity analysis of OpenAI’s AI chatbot, ChatGPT, shedding light on its potential risks.

Research Focus:
While previous research has focused on enhancing the power of large language models, little attention has been given to their safety. To address this gap, postdoctoral students from Princeton University and Georgia Tech collaborated with researchers from the Allen Institute for AI. Together, they performed a toxicity analysis of ChatGPT to assess its behavior when assigned different personas.

Evaluating Toxicity:
The researchers evaluated over half a million generations of ChatGPT and discovered that assigning a persona significantly increased its toxicity. For example, when ChatGPT was given the persona of boxer “Muhammad Ali,” its toxicity rose by nearly 3 times compared to default settings. This raises concerns as ChatGPT serves as a foundation for building other technologies that might replicate the same level of toxicity. The researchers aimed to gain deeper insights into this toxicity by exploring the effect of different personas on ChatGPT’s generations.

Methodology:
The ChatGPT API allows users to assign a persona that influences the way ChatGPT converses. The researchers compiled a list of 90 personas representing various backgrounds and countries, such as entrepreneurs, politicians, and journalists. They assigned these personas to ChatGPT and analyzed its responses across critical entities like gender, religion, and profession. The research team also prompted ChatGPT to complete certain phrases to better understand its biases and tendencies.

Findings:
The study revealed that assigning a persona to ChatGPT increased its toxicity by up to six times, resulting in harsh outputs and negative stereotypes. The toxicity varied significantly depending on the persona, suggesting that ChatGPT’s comprehension of people is influenced by its training data. The study also highlighted discriminatory behavior, with specific populations and entities being targeted more frequently than others. For instance, toxicity based on a person’s gender was approximately 50% higher than toxicity based on race.

Implications:
These fluctuations in toxicity pose potential harm to users and can be derogatory to individuals involved. Moreover, malicious users can exploit ChatGPT to generate harmful content. It is important to note that while ChatGPT was the model used in this study, the methodology can be applied to other large language models as well. The researchers hope that their work will encourage the development of ethical, secure, and reliable AI systems.

Conclusion:
Understanding the toxicity of AI chatbots like ChatGPT is essential for building safe and reliable AI systems. This research has shed light on the significant increase in toxicity when assigning personas, the variation in toxicity depending on persona identity, and the discriminatory targeting of specific entities. By uncovering these findings, the researchers aim to prompt the AI community to prioritize the development of ethical and secure AI technologies.
