OS-Helix: Unifying GUI Interaction and Code Execution in Native Computer-Using Agents

We present OS-Helix, an end-to-end trained multimodal computer-using agent that unifies GUI actions and code execution in one action space.

Key points

  • Real desktop automation is neither purely visual nor purely programmatic.
  • In our preliminary experiments, naively adding a code tool degrades a GUI agent, revealing that GUI/code routing must be internalized through training on high-quality hybrid data.
  • To construct the required supervision, we introduce application-artifact composition, pairing desktop applications with authentic file artifacts to instantiate executable Ubuntu states, and a decoupled instruction/evaluator generation pipeline that produces environment-grounded tasks whose final states can be verified regardless of the solution modality.
  • For RL, we propose Step-balanced GSPO, which aggregates importance weight by action step rather than raw assistant tokens to prevent long code actions from dominating heterogeneous-action optimization.
