CUA is an open-source platform that equips AI agents with real computers and automation tools: isolated cloud desktops (Cua Fleets), a cross-OS desktop automation interface (Cua Driver), local macOS/Linux VM tooling (Lume), and an evaluation and data-generation toolkit (Cua Bench). Cua Driver lets agents inspect and operate native apps and browsers on macOS, Windows, and Linux with background delivery when supported; demos include selecting spreadsheet cells and verifying Calculator output. Fleets provide sandboxed Linux desktops and a Sandbox SDK to run commands, capture screenshots, and manage lifecycle. Lume creates Apple Silicon VMs and connects via SSH. Tutorials and CLI install snippets are included for quick first results like provisioning a desktop, running uname -a, or checking an app result.
CUA-S1 is a family of small, specialist "System 1" models engineered for fast, bounded computer-use decisions - primarily form and structured-interface scoring rather than token-by-token generation. The project supplies Python model code, synthetic-data generation, training and evaluation workflows, and model weights hosted on Hugging Face; application code orders actions and optional Driver integration executes them with explicit action boundaries. Source is MIT-licensed, accompanied by model and dataset cards, safety and deployment guidance, and citation metadata. The repository is mature and active (thousands of commits, 24k+ stars) and intends to support reproducible research, benchmarking, and contributions for scaling agent interactions with GUIs and documents.
