  "title": "OS-Helix: Unifying GUI Interaction and Code Execution in Native Computer-Using Agents",
  "summary": "OS-Helix replaces prompt-level composition of a GUI agent plus a separate code tool with a single policy trained (SFT cold-start plus online RL with step-balanced GSPO) to route natively between GUI actions and code execution in one action space. The cost is substantial and out of reach here: it requires constructing executable Ubuntu environments with application-artifact composition, verifiable hybrid training data, RL in live desktop environments, and fine-tuning 27B-35B multimodal models, none of which fits a 24 GB GPU or a limited cloud budget. What can fail is that the learned GUI/code routing is tied to the training distribution of environments and artifacts, so transfer to unseen desktop applications or workflows may degrade, and long-horizon verifiable-task pipelines may not cover the reader's actual production tasks.",
  "rationale": "The method is relevant to desktop automation but depends on large-scale model training, custom environments, and online RL infrastructure that the reader's constrained setup cannot support, so it is worth tracking rather than adopting.",
