OpenGCUA: Toward a Fully Open Stack for Generalist Computer Use
OpenGCUA open-sources a generalist computer-use stack that lifts OSWorld-v2 scores and cuts steps.
OpenGCUA is a first release of an open stack for generalist computer-use agents that mix visual and programmatic interfaces, including code execution and harness-to-model decision transfer. On OSWorld-v2, the full configuration improved all eight evaluated models, including GPT-6 Astra and Claude Opus 5, raising mean partial score by 19.6 points and cutting reported steps per task by 53.0% versus batched GUI-only execution. The project releases code, prompts, trajectories, a preliminary real-device harness, and a cross-device SDK. On four real macOS tasks, selected Qwen3.8-Max runs used 19.4 times as many reasoning tokens as GPT-6 Astra.

Computer use has reached a turning point: the focus is expanding from GUI-only interaction to systems that complete tasks on users' computers through visual and programmatic interfaces. We define a generalist computer-use agent (GCUA) as a system in which the model chooses how to observe, act, and organize its work across visual and programmatic interfaces.
