Call For Code AI | Calling All Developers

The most urgent problems on earth need the most skilled people on earth.

Built on the world's largest developer mobilization for social good, Call for Code AI now channels that infrastructure toward the defining challenge of this era — building AI that can be trusted at global scale.

Founded in partnership with the Office of the United Nations High Commissioner for Human Rights (UN Human Rights), the platform operates across 190+ countries with direct alignment to the global policy frameworks that govern how technology is adopted, deployed, and scaled.

Over eight years, more than one million developers across 190+ countries built 50,000+ applications. The strongest were recognized at the United Nations, deployed in real communities, and open-sourced through the Linux Foundation.

Project OWL restored emergency communications in Puerto Rico after Hurricane Maria. Prometeo put AI-powered health monitoring on firefighters battling wildfires in Spain. These are examples of deployed technologies serving communities around the world — proof that this platform doesn’t just surface ideas. It sees them through.

AI is already embedded in the systems that shape daily life — healthcare decisions, financial access, emergency response, public infrastructure. The question is no longer what AI can do. It is whether the systems making those decisions can be tested, trusted, and held to account.

Call for Code AI is built for that question. A neutral proving ground for frontier AI systems — evaluating performance, safety, scalability, and alignment with human rights standards.

Not a hackathon. Structured infrastructure for responsible AI deployment at global scale.

The Call for Code AI Global Challenge mobilizes developers, enterprises, universities, and global institutions to build AI solutions designed for real-world deployment — not proof-of-concept, but production.

Solutions are developed in the open, validated through institutional frameworks, and the strongest are elevated to a global stage: recognized by the United Nations and supported toward deployment in communities worldwide.

Alongside the Global Challenge, Spot Challenges enable rapid mobilization around urgent issues as they emerge — operating within the same governance framework so that speed and accountability are never in conflict.

"Call for Code was built through extraordinary collaboration. IBM, United Nations Human Rights, and The Linux Foundation created a global platform where developers could apply their skills to the world's most pressing challenges — and over eight years, it grew into the largest developer mobilization of its kind.

What made it work was not technology alone. It was the alignment of innovation with institutions and a shared conviction that developers are among the most powerful agents of change in the world.

Today, AI is embedded in the systems that govern our societies — healthcare, justice, finance, public infrastructure. The responsibility to build technology that serves humanity has never been greater. The cost of getting it wrong has never been higher.

Call for Code AI exists because the developers who build the future should also be the ones who hold it accountable."
