LLMs struggle with complex GitHub issues, resolving only 1.96%

A new series on SWE-bench reliability highlights that current state-of-the-art large language models, including proprietary ones and fine-tuned versions like SWE-Llama, can only resolve a small fraction (1.96%) of real-world GitHub issues. This capability gap exists when problems require multi-file reasoning or systems-level understanding, rather than simple pattern matching. The author plans to develop a hybrid persona model to tackle these medium-complexity software engineering tasks where current models falter. AI

IMPACT Highlights the current limitations of LLMs in complex reasoning tasks, indicating a significant gap in their ability to handle real-world software engineering problems.

RANK_REASON The item discusses benchmark results and model capabilities on a specific task (SWE-bench), referencing an arXiv paper. [lever_c_demoted from research: ic=1 ai=1.0]
