GPT-4’s performance has declined while GPT-3.5 has shown improvement, according to researchers from Stanford University and UC Berkeley. These Large Language Models (LLMs) have become influential in the field of artificial intelligence, but their evolution can be puzzling. Minor updates to these models can result in significant variations in performance, leading to the need for vigilant monitoring.
The researchers conducted a comparative study of GPT-3.5 and GPT-4 versions from March 2023 to June 2023. They evaluated their performance in mathematics problem-solving, handling sensitive queries, generating code, and visual reasoning. The results revealed that even within a short span of time, the performance of the same LLM can undergo dramatic transformations.
Updates introduced to LLMs aim to enhance their functionality, but the reality is more complex. For example, GPT-4’s ability to recognize prime numbers plummeted from 97.6% accuracy in March 2023 to just 2.4% in June 2023. On the other hand, GPT-3.5 showed significant improvement in the same task during this period. These unpredictable changes underscore the importance of continuous monitoring.
The unpredictable nature of LLM updates poses a challenge when integrating them into larger workflows. A sudden change in the response of an LLM to a prompt can disrupt downstream processes and complicate result reproduction. Navigating this uncertainty is a significant challenge for both developers and users.
This study highlights the crucial need for persistent monitoring of LLM quality. As updates designed to enhance certain aspects of a model can inadvertently impact its overall performance, staying informed about these models’ capabilities is crucial.
Current research lacks sufficient monitoring of the longitudinal changes in widely used LLM services like GPT-4 and GPT-3.5 over time. Monitoring performance shifts has emerged as a vital aspect of deploying machine learning services in a rapidly evolving technological landscape.
The performance of LLMs can vary significantly across different tasks. In June 2023, GPT-4 was less responsive to sensitive queries compared to its performance in March. Additionally, both GPT-4 and GPT-3.5 exhibited an increase in formatting errors when generating code.
The behavior of LLMs, such as GPT-3.5 and GPT-4, can change significantly within a short period of time. As these models continue to evolve, understanding their performance across different tasks and assessing the impact of updates on their capabilities becomes even more crucial. Continuous monitoring and evaluation of these models are necessary to ensure stability and reliability.

In conclusion, the performance of GPT-4 has declined, while GPT-3.5 has shown improvement over time. The evolving nature of these models emphasizes the need for ongoing monitoring to understand their capabilities and ensure their reliability. As the influence of LLMs continues to grow, staying updated on their performance is of utmost importance.
