Overview

What is Cua Agent?

Cua Agent is an open‑source framework that combines high‑performance virtualization with AI agent capabilities, enabling secure, isolated environments for AI systems to interact with desktop applications. It offers a computer‑use interface for AI observation and control, running macOS or Linux virtual machines on Apple Silicon with near‑native performance.

How to use Cua Agent?

Install the Lume CLI via the provided install script, then install the Python libraries with pip install cua-computer cua-agent[all]. Use the library in Python code by creating a Computer and ComputerAgent, then calling agent.run(tasks). An optional Gradio UI is available for interactive use.

Key features of Cua Agent

  • High‑performance virtualization on Apple Silicon (up to 90% native speed)
