The Studies and Their Findings
Recently, a series of studies conducted by researchers from Stanford University and the University of California, Berkeley, have sparked a significant debate within the AI community. These studies primarily focus on the performance of OpenAI’s GPT-4 language model. The researchers published a paper titled “How Is ChatGPT’s Behavior Changing over Time?” on arXiv, which investigates the changes in GPT-4’s outputs over a few months. The findings suggest a potential decline in GPT-4’s abilities in coding and compositional tasks.
Methodology Employed
To conduct these studies, the researchers utilized API access to test GPT-3.5 and GPT-4 versions from March and June 2023. They tested these versions across various tasks, including math problem-solving, answering sensitive questions, code generation, and visual reasoning.
A Significant Drop in Performance: The Numbers
One of the most notable findings of the research was a significant drop in GPT-4’s ability to identify prime numbers. The accuracy plummeted from 97.6 percent in March to a mere 2.4 percent in June. This represents a staggering 95.2 percentage point drop in just a few months. Interestingly, GPT-3.5 displayed improved performance during the same period, showing that the decline was not universal across all versions of the model.
User Concerns and Speculations
These investigations come amidst growing concerns expressed by users who have observed a subjective decline in GPT-4’s performance over the past few months. There are various speculations about the reasons behind this decline. Some suggest that OpenAI might be distilling models to enhance efficiency or fine-tuning them to mitigate harmful outputs. There are also unfounded conspiracy theories suggesting a reduction in GPT-4’s coding capabilities to promote GitHub Copilot usage.
OpenAI’s Response to the Claims
Despite these concerns and speculations, OpenAI has consistently denied the alleged decrease in GPT-4’s capabilities. Peter Welinder, OpenAI’s VP of Product, recently took to Twitter to counter the claims. He asserted that each new version of the AI language model is more advanced than its predecessor. He also suggested that intensive usage might lead to heightened awareness of these perceived issues. However, OpenAI is not completely closed to the possibility of regressions and is actively investigating the matter.
No, we haven't made GPT-4 dumber. Quite the opposite: we make each new version smarter than the previous one.

Current hypothesis: When you use it more heavily, you start noticing issues you didn't see before.
Criticisms of the Study
The studies have not been without criticism. Arvind Narayanan, a computer science professor at Princeton, pointed out some problems in the study. He argued that the research’s findings do not definitively prove a decline in GPT-4’s performance. Instead, they could align with fine-tuning adjustments made by OpenAI.
We dug into a paper that’s been misinterpreted as saying GPT-4 has gotten worse. The paper shows behavior change, not capability decrease. And there's a problem with the evaluation—on 1 task, we think the authors mistook mimicry for reasoning.

The Ongoing Debate
These studies have ignited a contentious discussion within the AI community about the performance of OpenAI’s GPT-4 language model. The debate continues, and further research and analysis are necessary to ascertain the true nature of GPT-4’s capabilities and any potential changes over time. The dramatic drop in performance as indicated by the studies has raised serious questions about the stability and reliability of AI models, and the AI community is eagerly awaiting further updates on this issue.
