APEX-SWE: AI Productivity Index for Software Engineering → http://arxiv.org/abs/2601.08806v1

Researchers introduce a new benchmark that moves beyond narrow coding tasks to evaluate whether frontier AI models can execute economically valuable software engineering work. APEX-SWE assesses two novel task types that better reflect real-world development scenarios, addressing a critical gap in current AI evaluation methods. This benchmark could fundamentally change how we measure AI progress in software engineering, shifting focus from toy problems to actual productivity gains. The work comes from a team spanning multiple institutions and represents a significant step toward understanding AI's true impact on software development workflows.
