Today we're announcing cua-bench: a framework for benchmarking, training data, and RL environments for computer-use AI agents. Why? Current agents show 10x variance across minor UI changes. Here's how we're fixing it. 1/ The problem: Claude Computer-Use, OpenAI CUA, and Gemini 2.5 Computer-Use show 10x performance difference across minor UI changes.

Completes tasks on a clean desktop, fails when windows overlap. Works on default themes, breaks on high contrast mode.

The root cause: training data lacks visual diversity.Image

Introducing App-Use - create virtual desktops for AI agents to focus on specific apps.

1/6 App-Use lets you scope agents to just the apps they need. Instead of full desktop access, say "only work with Safari and Notes" or "just control iPhone Mirroring" - visual isolation without new processes for perfectly focused automation.

Cua loves MCP. Launching official MCP Server support today - enabling our Computer-Use Agent to run through Claude Desktop, Cursor, and other MCP clients. An example use case? How about using Claude as a tutor to learn how to use Tableau?
