AI can fix bugs—but can't find them: OpenAI's study highlights limits of LLMs in software engineering

OpenAI's recent research highlights the limitations of large language models (LLMs) in software engineering tasks. The study, utilizing a benchmark called SWE-Lancer, tested models like GPT-4o and Claude-3.5 Sonnet on real freelance coding tasks from Upwork. Results showed that while these models can solve bugs, they struggle to understand the underlying issues, leading to frequent mistakes.

The research involved 1,488 tasks with a total payout of $1 million, divided into individual contributor and management tasks. Despite Claude 3.5 Sonnet performing the best, it only resolved 26.2% of issues correctly, indicating that LLMs cannot yet replace human engineers. The findings suggest that while LLMs can assist in coding, they still require significant improvement to be reliable in real-world applications.

• LLMs struggle to identify root causes of coding issues.

• Claude 3.5 Sonnet was the best-performing model in the study.
