SWE-bench: Evaluating Language Models for Real-World Software Engineering Challenges

AI Language Models: Assessing their Proficiency in Real-World Software Engineering Challenges


When it comes to advancing language models (LMs), evaluating their ability to tackle real-world software engineering challenges is crucial. SWE-bench is an innovative evaluation framework that uses GitHub issues and pull requests from Python repositories to assess the capabilities of these models. Surprisingly, the findings reveal that even the most advanced LMs struggle with complex issues. This highlights the urgent need for further advancements in LM technology to enable practical and intelligent solutions in software engineering.

The Importance of Real-World Evaluation

Existing evaluation frameworks for LMs often lack versatility and fail to address the complexity of real-world software engineering tasks. Current benchmarks for code generation are unable to capture the depth of these challenges. The SWE-bench framework, developed by researchers from Princeton University and the University of Chicago, stands out by focusing on real-world software engineering issues, such as patch generation and complex context reasoning. This comprehensive evaluation approach enhances the capabilities of language models in the field of Machine Learning for Software Engineering.

The Need for Robust Benchmarks

As language models are widely used in commercial applications, there is a need for robust benchmarks to evaluate their capabilities. Existing benchmarks must be able to challenge LMs with real-world tasks. Software engineering tasks offer a compelling challenge due to their complexity and verifiability through unit tests. SWE-bench leverages GitHub issues and solutions to create a practical benchmark for evaluating LMs in a software engineering context. This approach promotes real-world applicability and continuous updates.

Evaluation Findings

The research conducted included 2,294 real-world software engineering problems from GitHub. LMs were tasked with resolving issues across functions, classes, and files in codebases. The model inputs consisted of task instructions, issue text, retrieved files, an example patch, and a prompt. The performance of the LMs was evaluated under two context settings: sparse retrieval and oracle retrieval.

The evaluation results indicate that even state-of-the-art models like Claude 2 and GPT-4 struggle to resolve real-world software engineering issues. These models achieved pass rates as low as 4.8% and 1.7%, even with the best context retrieval methods. The models performed even worse when dealing with longer contexts and showed sensitivity to variations in context. They tended to generate shorter and poorly formatted patch files, highlighting the challenges in handling complex code-related tasks.

The Future of LM Evaluation

As LM technology advances, it is crucial to comprehensively evaluate them in practical, real-world scenarios. The SWE-bench evaluation framework serves as a challenging and realistic testbed for assessing the capabilities of next-generation LMs in the context of software engineering. The evaluation results revealed the current limitations of even state-of-the-art LMs in handling complex software engineering challenges. These findings emphasize the necessity of developing more practical, intelligent, and autonomous LMs.

Several avenues for advancing the SWE-bench evaluation framework were proposed by the researchers. Suggestions include expanding the benchmark with a broader range of software engineering problems, exploring advanced retrieval techniques, and adopting multi-modal learning approaches to enhance the performance of language models. Addressing limitations in understanding complex code changes and improving the generation of well-formatted patch files were also highlighted as important areas for future exploration. These steps aim to create a more comprehensive and effective evaluation framework for language models in real-world software engineering scenarios.


Evaluating the proficiency of language models in real-world software engineering tasks is essential for their progress. SWE-bench provides a challenging and comprehensive evaluation framework that highlights the limitations of current LMs and suggests avenues for improvement. By addressing the complexity of software engineering challenges, this evaluation framework promotes the development of practical, intelligent, and autonomous language models.
