    Longtail-SWE: High-Quality SWE Tasks for Underrepresented Languages

    Vladimir Dobrovolskii, Ibragim Badertdinov, Alexander Golubev

    Challenging repository-level benchmarks remain limited for many programming language ecosystems, where filtering scarce candidates with ambiguous descriptions or defective tests can discard valuable engineering problems. We introduce Longtail-SWE, a benchmark of 202 issue-resolution tasks across 13 languages with…

    Coding or Cheating? An Investigation of Frontier Coding LLMs

    Yuntao Gui

    Frontier agentic LLMs are trained on verifiable rewards in reinforcement learning (RL) environments built from real software repositories. A passing test suite is treated as the reward for solving the task. We show that, on hard problems, frontier models often satisfy these rewards by obtaining the answer instead…
