A Staff of researchers from USC, Salesforce AI and College of Washington have launched CoAct-1, a pioneering multi-agent computer-using agent (CUA) that marks a major leap in autonomous laptop operation. By elevating coding to a first-class motion—on par with conventional GUI manipulation—CoAct-1 overcomes longstanding challenges of effectivity and reliability in complicated, long-horizon laptop duties. On the demanding OSWorld benchmark, CoAct-1 units a brand new gold customary, reaching a state-of-the-art (SOTA) success charge of 60.76%, making it the primary CUA agent to surpass the 60% mark.
Why CoAct-1? Bridging the Effectivity Hole in Pc-Utilizing Brokers
Standard CUA brokers rely solely on pixel-based GUI interplay—emulating human customers by clicking, typing, and navigating interfaces. Whereas this method mimics person workflows, it proves fragile and inefficient for intricate, multi-step duties, particularly these involving dense UI layouts, multi-app pipelines, or complicated OS operations. Single errors comparable to a mis-click can derail complete workflows, and sequence lengths balloon as duties enhance in complexity.
Efforts to mitigate these points have included augmenting GUI brokers with high-level planners, as seen in techniques like GTA-1 and modular multi-agent frameworks. Nonetheless, these strategies can’t escape the bottleneck of GUI-centric motion areas, finally limiting each effectivity and robustness.
CoAct-1: Hybrid Structure with Coding as Motion
CoAct-1 takes a basically completely different method by integrating three specialised brokers:
- Orchestrator: The high-level planner that decomposes complicated duties and dynamically delegates every subtask both to the Programmer or the GUI Operator primarily based on process necessities.
- Programmer: Executes backend operations—file administration, information processing, atmosphere configuration—immediately by way of Python or Bash scripts, bypassing cumbersome GUI motion sequences.
- GUI Operator: Makes use of a vision-language mannequin to work together with visible interfaces when human-like UI navigation is indispensable.
This hybrid mannequin permits CoAct-1 to strategically substitute brittle and prolonged mouse-keyboard operations with concise, dependable code execution, whereas nonetheless leveraging GUI interactions the place needed.
Analysis on OSWorld: Document-Setting Efficiency
OSWorld—a number one benchmark that includes 369 duties spanning workplace productiveness, IDEs, browsers, file managers, and multi-app workflows—proves an exacting testbed for agentic techniques. Every process mirrors real-world language objectives and is assessed by a granular rule-based scoring system.
Outcomes
- General SOTA Success Charge: CoAct-1 achieves 60.76% on the 100+ step class—the primary CUA agent to cross the 60-point threshold. This outpaces GTA-1 (53.10%), OpenAI CUA 4o (31.40%), UI-TARS-1.5 (29.60%), and different main frameworks.
- Stepped Allowance Efficiency: At a 100-step price range, CoAct-1 scores 59.93%, once more main all rivals.
- Effectivity: Completes duties with a median of 10.15 steps per profitable process, in comparison with 15.22 for GTA-1, 14.90 for UI-TARS, and with a lot larger success than OpenAI CUA 4o, which, regardless of fewer steps (6.14), achieves solely 31.40% success.
Breakdown
CoAct-1 dominates throughout process varieties, with particularly giant features in workflows benefitting from code execution:
- Multi-App: 47.88% (vs. GTA-1’s 38.34%)
- OS Duties: 75.00%
- VLC: 66.07%
- In productiveness and IDE domains (LibreOffice Calc, Author, VSCode), it persistently leads or ties with the SOTA.
Key Insights: What Drives CoAct-1’s Positive aspects?
- Coding Actions Change Redundant GUI Sequences: For operations like batch picture resizing or superior file manipulations, single scripts exchange dozens of error-prone clicks, lowering each steps and threat of failure.
- Dynamic Delegation: The Orchestrator’s versatile process task ensures optimum use of coding vs. GUI actions.
- Enchancment with Stronger Backbones: The most effective configuration makes use of OpenAI CUA 4o for the GUI Operator, OpenAI o3 for the Orchestrator, and o4-mini for the Programmer, reaching the highest 60.76% rating. Programs utilizing solely smaller or much less succesful backbones rating considerably decrease.
- Effectivity Correlates with Reliability: Fewer steps immediately scale back alternatives for error—the only strongest predictor of profitable completion.
Conclusion: A Leap Ahead in Generalized Pc Automation
By making coding a first-class system motion alongside GUI manipulation, CoAct-1 delivers each a quantum leap in success and effectivity, and illustrates the sensible path ahead for scalable, dependable autonomous laptop brokers. Its hybrid structure and dynamic execution logic set a brand new high-water mark for the CUA subject, heralding sturdy advances in real-world laptop automation.
