Do Coding Agents Reuse Existing Code or Reinvent the Wheel?

Dongsheng Ma, Sizhe Wang, Xinyi Huang وآخرون · 2026

Coding agents are increasingly deployed for iterative development on real repositories, yet existing evaluation barely answers a basic question: \emph{do coding agents reuse existing code or reinvent the wheel?} The question matters: every duplicated implementation is a fix applied twice and agents produce code far fas …

RoboFFT: Finetuning generative robot policy via online reinforcement learning with forward process

Yu Li, Shenghe Hu, Yuhan Wang وآخرون · 2026

Generative models, such as diffusion and flow-based models, have shown strong promise for robot policy learning by capturing complex and multimodal action distributions from demonstrations. However, policies trained solely with imitation learning often suffer from imperfect demonstrations and distributional shifts, whi …
