Quick takeaways
Large language models (LLMs) perform better in higher-level programming languages and struggle with lower-level languages due to increased complexity and the absence of automated tools.
LLMs perform well even in relatively unpopular languages like Julia, challenging the notion that the volume of available examples on the internet determines LLM performance and raising questions about how we evaluate the suitability of languages for code generation through LLMs.
Deep dives
Performance Variation Across Languages
The study observed significant variations in the performance of large language models (LLMs) in code generation across different programming languages. Python was found to perform the best, followed by Julia, JavaScript, Ruby, NR (R language), Perl, and Smalltalk. Lower-level languages such as C++, C, and Go exhibited lower performance, but still outperformed expectations. The results suggest that LLMs tend to perform better in higher-level languages and struggle more with lower-level languages due to increased complexity and the absence of automated tools like garbage collectors.
Impact of Language Popularity on LLM Performance
Contrary to expectations, the study revealed that LLMs performed well even in relatively unpopular languages like Julia, challenging the notion that the volume of available examples on the internet determines LLM performance. This finding raises questions about how we evaluate the suitability of languages for code generation through LLMs. If certain languages consistently outperform popular languages with lesser available examples, it could disrupt industry trends and prompt a shift towards languages optimized for LLM-based code generation.
Ethical Considerations and Code Generation
The study also explored the ethical implications of code generation through LLMs. Surprisingly, the ethical assessments of generated code varied across languages, with some languages yielding unethical outputs for specific tasks. This suggests that LLMs might struggle to understand and adhere to ethical guidelines in code-related tasks, posing risks in areas like security. The results emphasize the need for further investigation and the establishment of fair benchmarks for evaluating the ethical aspects of LLM-generated code across different languages.
Future Directions and New LLM Models
As the field of large language models continues to evolve, the study highlights the potential impact of future LLM models, such as Chat GPT 4 and models like Mistral and LAMDA. The researcher expressed interest in repeating the study with newer models and open-source alternatives. Additionally, future investigations will explore sentiment analysis and plagiarism detection, showcasing the broad range of applications and challenges within the field.
In this episode, we have Alessio Buscemi, a software engineer at Lifeware SA. Alessio was a post-doctoral researcher at the University of Luxembourg. He joins us to discuss his paper, A Comparative Study of Code Generation using ChatGPT 3.5 across 10 Programming Languages. Alessio shared his thoughts on whether ChatGPT is a threat to software engineers. He discussed how LLMs can help software engineers become more efficient.
