Replay: Open Source Friday Cua with Francesco Bonacci
Francesco Bonacci joins GitHub’s Open Source Friday to discuss Cua’s approach to computer-use agents, including the Lum and Cua Driver projects, how they benchmark and evaluate agent behavior, and what changes when you move from screenshot-driven automation to more policy-driven, capable agents.
Overview
What the session focuses on
The conversation explores the future of computer-use agents and how Cua is building an open-source ecosystem around them.
Cua’s open-source ecosystem
The video highlights Cua’s projects and supporting work, including:
- Lum
- Cua Driver
- Benchmarks used to evaluate computer-use agent capabilities
From “computer use 1.0” to policy-driven agents
Francesco describes a shift from screenshot-based approaches (“computer use 1.0”) toward more capable agents that are policy-driven, with an emphasis on controlling and constraining behavior.
Building and shipping with coding agents
The discussion covers how the team builds with coding agents, including practical workflow considerations for using agentic tooling while keeping momentum in a fast-moving AI space.
Security and evaluation
The session also touches on how Cua approaches:
- Security considerations for computer-use agents
- Evaluation and benchmarking practices to measure progress and reliability
Working in the open
Francesco shares how the team collaborates with open-source contributors and stays focused while the broader AI landscape changes quickly.
