Researchers at Salesforce and the College of Southern California have developed a brand new method that offers computer-use brokers the flexibility to execute code whereas navigating graphical person interfaces (GUIs), that’s, writing scripts whereas additionally shifting a cursor and/or clicking buttons on an utility, combining one of the best of each approaches to hurry up workflows and cut back errors.
This hybrid strategy permits an agent to bypass brittle and inefficient mouse clicks for duties that may be higher achieved by way of coding.
The system, known as CoAct-1, units a brand new state-of-the-art on key agent benchmarks, outperforming different strategies whereas requiring considerably fewer steps to perform complicated duties on a pc.
This improve can pave the way in which for extra sturdy and scalable agent automation with important potential for real-world purposes.

The fragility of point-and-click AI brokers
Pc use brokers sometimes depend on vision-language and vision-language-action fashions (VLMs or VLAs) to understand a display and take motion, mimicking how an individual makes use of a mouse and keyboard.
Whereas these GUI-based brokers can carry out quite a lot of duties, they typically falter when confronted with lengthy, complicated workflows, particularly in purposes with dense menus and choices, like workplace productiveness suites.
For instance, a activity that includes finding a selected desk in a spreadsheet, filtering it, and saving it as a brand new file can contain a protracted and exact sequence of GUI manipulations.
That is the place brittleness creeps in. “In these situations, present brokers regularly wrestle with visible grounding ambiguity (e.g., distinguishing between visually related icons or menu objects) and the gathered likelihood of constructing any single error over the lengthy horizon,” the researchers write in their paper. “A single mis-click or misunderstood UI factor can derail the complete activity.”
To deal with these challenges, many researchers have targeted on augmenting GUI brokers with high-level planners.
These programs use highly effective reasoning fashions like OpenAI’s o3 to decompose a person’s high-level purpose right into a sequence of smaller, extra manageable subtasks.
Whereas this structured strategy improves efficiency, it doesn’t resolve the issue of navigating menus and clicking buttons, even for operations that might be achieved extra straight and reliably with just a few traces of code.
CoAct-1: A multi-agent workforce for laptop duties
To unravel these limitations, the researchers created CoAct-1 (Pc-using Agent with Coding as Actions), a system designed to “mix the intuitive, human-like strengths of GUI manipulation with the precision, reliability, and effectivity of direct system interplay by way of code.”
The system is structured as a workforce of three specialised brokers that work collectively: an Orchestrator, a Programmer, and a GUI Operator.
The Orchestrator acts because the central planner or challenge supervisor. It analyzes the person’s general purpose, breaks it down into subtasks, and assigns every subtask to one of the best agent for the job. It could delegate backend operations like file administration or knowledge processing to the Programmer, which writes and executes Python or Bash scripts.
For frontend duties that require clicking buttons or navigating visible interfaces, it turns to the GUI Operator, a VLM-based agent.
“This dynamic delegation permits CoAct-1 to strategically bypass inefficient GUI sequences in favor of sturdy, single-shot code execution the place applicable, whereas nonetheless leveraging visible interplay for duties the place it’s indispensable,” the paper states.
The workflow is iterative. After the Programmer or GUI Operator completes a subtask, it sends a abstract and a screenshot of the present system state again to the Orchestrator, which then decides the following step or concludes the duty.
The Programmer agent makes use of an LLM to generate its code and sends instructions to a code interpreter to check and refine its code over a number of rounds.
Equally, the GUI Operator makes use of an motion interpreter that executes its instructions (e.g., mouse clicks, typing) and returns the ensuing screenshot, permitting it to see the result of its actions. The Orchestrator makes the ultimate choice on whether or not the duty ought to proceed or cease.
A extra environment friendly path to automation
The researchers examined CoAct-1 on OSWorld, a complete benchmark that features 369 real-world duties throughout browsers, IDEs, and workplace purposes.
The outcomes present CoAct-1 establishes a brand new state-of-the-art, reaching successful fee of 60.76%.
The efficiency positive factors have been most vital in classes the place programmatic management affords a transparent benefit, corresponding to OS-level duties and multi-application workflows.
For example, take into account an OS-level activity like discovering all picture recordsdata inside a fancy folder construction, resizing them, after which compressing the complete listing right into a single archive.
A purely GUI-based agent would want to carry out a protracted, brittle sequence of clicks and drags, opening folders, deciding on recordsdata, and navigating menus, with a excessive likelihood of error at every step.
CoAct-1, against this, can delegate this complete workflow to its Programmer agent, which might accomplish the duty with a single, sturdy script.
Past only a larger success fee, the system is dramatically extra environment friendly. CoAct-1 solves duties in a median of simply 10.15 steps, a stark distinction to the 15.22 steps required by main GUI-only brokers like GTA-1.
Whereas different brokers like OpenAI’s CUA 4o averaged fewer steps, their general success fee was a lot decrease, indicating CoAct-1’s effectivity is coupled with better effectiveness.
The researchers discovered a transparent pattern: duties that require extra actions usually tend to fail. Lowering the variety of steps not solely hurries up activity completion however, extra importantly, minimizes the alternatives for error.
Due to this fact, discovering methods to compress a number of GUI steps right into a single programmatic activity could make the method each extra environment friendly and fewer error-prone.
Because the researchers conclude, “This effectivity underscores the potential of our strategy to pave a extra sturdy and scalable path towards generalized laptop automation.”
From the lab to the enterprise workflow
The potential for this expertise goes past basic productiveness. For enterprise leaders, the important thing lies in automating complicated, multi-tool processes the place full API entry is a luxurious, not a assure.
Ran Xu, a co-author of the paper and Director of Utilized AI Analysis at Salesforce, factors to buyer assist as a major instance.
“A service assist agent makes use of many various instruments — basic instruments corresponding to Salesforce, industry-specific instruments corresponding to EPIC for healthcare, and lots of custom-made instruments — to research a buyer request and formulate a response,” Xu advised VentureBeat. “A number of the instruments have API entry whereas others don’t. It’s a good use case that would probably profit from our expertise: a compute-use agent that leverages no matter is out there from the pc, whether or not it’s an API, code, or simply the display.”
Xu additionally sees high-value purposes in gross sales, corresponding to prospecting at scale and automating bookkeeping, and in advertising for duties like buyer segmentation and marketing campaign asset technology.
Navigating real-world challenges and the necessity for human oversight
Whereas the outcomes on the OSWorld benchmark are sturdy, enterprise environments are far messier, full of legacy software program and unpredictable UIs.
This raises essential questions on robustness, safety, and the necessity for human oversight.
A core problem is guaranteeing the Orchestrator agent makes the best selection when confronted with an unfamiliar utility. In line with Xu, the trail to creating brokers like CoAct-1 sturdy for customized enterprise software program includes coaching them with suggestions in reasonable, simulated environments.
The purpose is to create a system the place the “agent may observe how human brokers work, get educated inside a sandbox, and when it goes reside, proceed to resolve duties below the steerage and guardrail of a human agent.”
The flexibility for the Programmer agent to execute its personal code additionally introduces apparent safety considerations. What stops the agent from executing dangerous code based mostly on an ambiguous person request?
Xu confirms that sturdy containment is crucial. “Entry management and sandboxing is the important thing,” he mentioned, emphasizing {that a} human should “perceive the implication and provides the AI entry for security.”
Sandboxing and guardrails will likely be essential to validating agent habits earlier than deployment on essential programs.
Finally, for the foreseeable future, overcoming ambiguity will possible require a human-in-the-loop. When requested about dealing with imprecise person queries, a priority additionally raised within the paper, Xu steered a phased strategy. “I see human-in-the-loop to start out,” he famous.
Whereas some duties might finally change into absolutely autonomous, for high-stakes operations, human validation will stay essential. “Some mission-critical ones might all the time want human approval.”
