Decoding GPT-4 Turbo: A Winter Tale of AI Productivity

by Barry P Chaiken, MD

A recent study has revealed a fascinating aspect of OpenAI’s GPT-4 Turbo. The study, conducted by LLM enthusiast Rob Lynch, found that GPT-4 Turbo produces shorter responses when it believes the current month is December compared to May. Through a series of tests, he discovered that the LLM’s output in December averaged 4,086 tokens, about 5% less than its May output of 4,298 tokens over 477 test runs.

Ethan Mollick, a professor at Wharton, suggests that this phenomenon may be due to the LLM learning from human behavior, particularly the tendency to reduce work during the holiday-heavy month of December. This observation raises intriguing questions about the influence of human behavior and biases on AI systems despite efforts to minimize such impacts.

Importance of Continuous Vigilance

For healthcare, this finding is significant. It underscores the importance of understanding and mitigating the inadvertent transfer of human biases and behaviors into AI systems, especially in healthcare applications where precision and consistency are paramount. In informatics, where AI is increasingly used for diagnostics, patient management, and treatment planning, any variability in AI performance based on time-related biases could have profound implications.

This study serves as a reminder that while AI offers transformative potential in healthcare, continuous vigilance is required to ensure these tools remain reliable and unbiased. As AI systems like GPT-4 Turbo become more integrated into healthcare, it is crucial to understand their limitations and the nuances of their performance. Similar to calibrating lab equipment, prior testing and retesting must be part of the regular maintenance of AI-driven systems. This understanding will be vital in harnessing AI’s full potential to improve patient care, enhance healthcare delivery, and support public health initiatives.
