Modern chatbots powered by Large Language Models (LLMs) have revolutionized the way we interact with artificial intelligence. These chatbots are constantly learning and evolving to provide more accurate and useful responses. However, recent studies have brought to light the concerning possibility that learning doesn’t always equate to improvement. In fact, chatbots can experience a decline in performance over time, leading to implications for the future of AI and its developers.
The Decline of Chatbot Performance
Researchers conducted an experiment comparing the outputs of two LLMs, GPT-3.5 and GPT-4, in March and June 2023. The results were striking – in just three months, the accuracy of GPT-4 dropped significantly on certain tasks. For example, its ability to identify prime numbers declined from 97.6% to 2.4%. Moreover, the study revealed deterioration in AI output quality across various skills.
The Challenge of Live Training Data
The heart of machine learning lies in the training process, where AI models process vast amounts of data to emulate human intelligence. Modern chatbots have been developed using extensive online repositories, such as Wikipedia articles. However, once released into the wild, chatbots face challenges in maintaining the quality and accuracy of their training data. They are exposed to web-scraped content, which can be manipulated, leading to incorrect answers and a decline in performance.
Data Poisoning as a Threat
Chatbots are particularly susceptible to data poisoning, as seen with Microsoft’s Twitter bot Tay in 2016. Trolls manipulated Tay’s learning by bombarding it with abusive content, resulting in offensive tweets. Similarly, contemporary chatbots are vulnerable to similar attacks, where intentionally corrupted data can harm their performance.
Model Collapse: A Ticking Time Bomb
The proliferation of AI-generated content poses another threat known as “model collapse.” When AI-generated materials are used as training data, ML models start forgetting previous learnings and amplify their mistakes. This phenomenon has implications for the future of generative AI, as it could lead to a decline in chatbot performance if the AI-generated content becomes more prevalent.
The Importance of Reliable Content
To counter declining performance, AI developers must prioritize reliable content sources. Access to high-quality training data becomes crucial in protecting chatbots from the degenerative effects of low-quality or manipulated data. Companies controlling such content sources may hold the keys to further innovation in the AI space.

Conclusion
The challenges posed by declining chatbot performance call for vigilance and innovation from AI developers. To ensure that chatbots remain functional and beneficial, developers must address emerging data challenges, guard against data poisoning, and carefully assess the impact of AI-generated content on model collapse. By focusing on reliable content sources and staying vigilant against potential threats, the future of AI, including chatbots like ChatGPT, can continue to evolve and positively impact various industries.
