Give it a screenshot, it decides where to click, what to type, when to scroll. Give it a task in plain language, it operates a computer from start to finish — opening apps, navigating between pages, filling forms, reading results. It recovers from mistakes, generalizes across desktop environments, and outperforms open-source models at twice its size. Built for computer-use loops where every step is a model call. --- --- Context 64K tokens Training GUI reinforcement learning Input Text + screenshot Output GUI actions — click , type , scroll , key , drag , ...
