Examining the Claims: Are 52% of ChatGPT's Coding Responses Wrong?
Written on
Chapter 1: Introduction to ChatGPT and Its Impact
The emergence of large language models (LLMs) has led to innovative solutions, one of which is ChatGPT—an AI chatbot that extends beyond natural language processing. Programmers frequently utilize it to seek answers to their coding inquiries. While it excels in addressing straightforward questions that have clear responses online, its reliability is now under scrutiny.
This article stems from a discussion that gained traction on Medium, focusing on recent developments in ChatGPT's capabilities, including its ability to browse linked content for additional context. Despite its impressive range of functions, developers have begun to notice that ChatGPT's responses can sometimes be inaccurate or misleading.
To illustrate this, I conducted an experiment with the latest model by querying it about the Kotlin release notes, specifically asking for the most amusing update among approximately 150 changes. Surprisingly, ChatGPT pointed out a supposed bug fix related to emojis, which I later found to be nonexistent. This incident raises concerns about the chatbot's ability to fabricate details, including ticket names and numbers, which could easily mislead users.
ChatGPT's tendency to produce questionable information poses significant risks, particularly in programming, where incorrect code can lead to vulnerabilities and unexpected results, not to mention increased maintenance costs. Although many developers have anecdotes about their experiences with ChatGPT, we lack comprehensive data for broader conclusions.
Recently, a study was published, aiming to determine whether the issues experienced are isolated or widespread.
Section 1.1: Investigating the 52% Error Rate Claim
The study that sparked the media frenzy is titled "Is Stack Overflow Obsolete? An Empirical Study of the Characteristics of ChatGPT Answers to Stack Overflow Questions." Released in February 2024, this research analyzed ChatGPT's accuracy in responding to coding queries.
Media outlets reported that 52% of ChatGPT's responses were incorrect, a claim that merits further examination. The fact that the research paper is nearly a year old raises questions about its relevance, especially given that it does not account for the latest iterations of ChatGPT.
The abstract reveals:
"Our analysis shows that 52% of ChatGPT answers contain incorrect information."
This distinction between incorrect answers and answers containing inaccuracies is significant and suggests that media reports may have exaggerated the chatbot's shortcomings.
Section 1.2: What the Research Actually Found
Conducted by researchers from Purdue University, the study evaluated 517 StackOverflow questions using the free version of ChatGPT 3.5. Notably, if ChatGPT was trained on StackOverflow data, it should have been able to provide accurate answers without needing to generate them from scratch.
The researchers discovered that not only did 52% of the answers contain errors, but also 77% included redundant or irrelevant information. The study emphasizes that ChatGPT's content generation is an auto-regressive process, which means it cannot predict the outcome of generated code.
Interestingly, the study found that ChatGPT performed better with older, more frequently asked questions, suggesting it is more adept at reformatting existing knowledge rather than generating entirely new insights.
Subsection 1.2.1: Developer Perspectives
A survey involving 12 developers revealed that they preferred StackOverflow responses over those from ChatGPT, citing their accuracy and quality. While some developers found ChatGPT's answers comprehensive, they often overlooked inaccuracies.
Chapter 2: Summary and Conclusion
In summary, while the research uncovers valuable insights, it also highlights the potential for ChatGPT to deliver misleading information. My own experience, where ChatGPT provided a structured response to a query about converting image formats in JavaScript, exemplifies this issue.
Although AI can be a helpful tool in programming, it is not a definitive solution. Developers must remain vigilant and knowledgeable enough to assess the accuracy of ChatGPT's outputs.
