Coherence Collapse: Diagnosing Why Code Agents Fail After Reaching the Right Code

Myeongsoo Kim, Dingmin Wang, Siwei Cui +6

Code agents resolve 65-70% of SWE-bench Verified issues, but Pass@1 cannot tell us why the rest fail, and, as we show, capable-model failures are systematically misdiagnosed withou…

CodeFort: Robust Training for Code Generation Models

Yuhao Zhang, Shiqi Wang, Haifeng Qian +8

Code generation models are not robust to small perturbations, which often lead to incorrect generations and significantly degrade the performance of these models. Although improvin…
