Cua is an open-source system that enables AI agents to use computers through desktop automation, cloud desktops, and local VMs. It provides tools like Cua Fleets for cloud provisioning, Cua Driver for app interaction, Lume for VM management, and Cua Bench for task evaluation and benchmarking.
Cua introduced CUA-S1, a family of specialized System One models designed for computer use, with CUA-S1-FORMS now open-sourced as the first release. The model efficiently fills forms in a single pass by selecting from predefined actions (FILL, CHECK, CLICK, SKIP) and outperforms general LLM agents on bounded, repetitive tasks.
