Cua demonstrates unique strengths in the following areas:
1. Performance advantages
With Apple's Virtualization.Framework technology, Cua is able to achieve near-native 90% performance on Apple Silicon devices, which is well above the typical performance loss of 20-40% for traditional virtualization tools.
2. AI agent integration
Cua natively supports AI agent control of VMs, which is not available in most virtualization tools. It can:
- Recognizing the Virtual Machine Interface via Screenshots
- Performs complex tasks such as browser manipulation and code writing
- Direct integration of OpenAI, Anthropic and other multilingual models
3. Secure design
- Complete sandbox isolation ensures that all operations of the AI agent are confined to the virtual machine
- Especially suited for testing insecure code or applications
- Protect the main system environment from contamination
4. Accessibility
Both command line tools (Lume CLI) and Python libraries are provided for management, allowing users to choose between simple VM management or full AI agent functionality depending on their needs.
