Definition
Plain language
A training recipe that teaches a small AI to know when to click around a screen and when to call a structured tool.
As stated in the literature
A three-stage training pipeline for computer-use agents combining synthetic hybrid-trajectory generation, single-turn RL on switching steps, and online RL with tool-appropriateness and path-efficiency rewards.
Why it matters: It tackles a real deployment problem where computer-use agents either over-rely on clicking or over-rely on tools instead of choosing the right one per task.
For example, ToolCUA trains an agent to call a calendar API when asked 'am I free Thursday?' but to actually click through a website when asked to fill an unfamiliar form.
