A recent study commissioned by Microsoft shows the lack of advancement AI models have in real AI work such as software debugging. The study compared nine different AI models head-to-head. It paid particular attention to their performance as a “single prompt-based agent,” using a wide range of debugging tools including a Python debugger. AI is quickly becoming an embedded partner in coding roles. Yet, despite their proficiency at many problem-solving tasks, these models have been challenged with completing debugging tasks in an effective manner.
Claude 3.7 Sonnet turned out to be the best overall model in the study. It scored a staggering average success rate of 48.4% in its code completion tasks. OpenAI’s o1 model cracked an amazing 30.2% of the test cases. The smaller o3-mini model compared very poorly at a rate of only 22.1%. The agent had difficulties and was unable to successfully perform the majority of debugging tasks (> 50%). All of these tasks fit under a well-crafted umbrella of 300 challenges sampled from SWE-bench Lite.
This study contributes to the ongoing dialogue among tech leaders regarding the capabilities and future roles of AI in programming. Critics have long challenged the idea that AI will fully automate programming jobs. Google CEO Sundar Pichai noted that as of October, 25% of new code at the company is generated by AI, highlighting a growing reliance on these technologies. In much the same way, Meta CEO Mark Zuckerberg has stated plans to use AI coding models extensively across his company.
Despite these advancements, limitations remain evident. Even Devin, one of the most popular AI coding tools, only passed 15% of programming exams. Replit CEO Amjad Masad, Okta CEO Todd McKinnon, and IBM CEO Arvind Krishna agree with that. They all understand the amazing things AI can do when it comes to doing programming work now. Microsoft co-founder Bill Gates has made it clear that he believes the profession of programming is not going away anytime soon, either.
The co-authors of the new Microsoft study acknowledged the room for betterment. As they assured, “We are firmly convinced that training or fine-tuning [models] can turn them into superior interactive debuggers.” This pearl of wisdom is encouraging since it indicates that current, struggling models can be improved and strengthened.
