cua-agent 0.5.2

CUA (Computer Use) Agent for AI-driven computer interaction

cua-agent is a general Computer-Use framework with liteLLM integration for running agentic workflows on macOS, Windows, and Linux sandboxes. It provides a unified interface for computer-use agents across multiple LLM providers with advanced callback system for extensibility.

Features

• Safe Computer-Use/Tool-Use: Using Computer SDK for sandboxed desktops
• Multi-Agent Support: Anthropic Claude, OpenAI computer-use-preview, UI-TARS, Omniparser + any LLM
• Multi-API Support: Take advantage of liteLLM supporting 100+ LLMs / model APIs, including local models (huggingface-local/, ollama_chat/, mlx/)
• Cross-Platform: Works on Windows, macOS, and Linux with cloud and local computer instances
• Extensible Callbacks: Built-in support for image retention, cache control, PII anonymization, budget limits, and trajectory tracking

Install

pip install "cua-agent[all]"

Quick Start

import asyncio
import os
from agent import ComputerAgent
from computer import Computer

async def main():
    # Set up computer instance
    async with Computer(
        os_type="linux",
        provider_type="cloud",
        name=os.getenv("CUA_CONTAINER_NAME"),
        api_key=os.getenv("CUA_API_KEY")
    ) as computer:

        # Create agent
        agent = ComputerAgent(
            model="anthropic/claude-sonnet-4-5-20250929",
            tools=[computer],
            only_n_most_recent_images=3,
            trajectory_dir="trajectories",
            max_trajectory_budget=5.0  # $5 budget limit
        )

        # Run agent
        messages = [{"role": "user", "content": "Take a screenshot and tell me what you see"}]

        async for result in agent.run(messages):
            for item in result["output"]:
                if item["type"] == "message":
                    print(item["content"][0]["text"])

if __name__ == "__main__":
    asyncio.run(main())
