UN rights chief urges urgent global action to govern frontier AI, warns of unprecedented risks

The United Nations human rights chief, Volker Turk, has called on countries and leading artificial intelligence companies to act urgently to govern advanced AI, warning that the technology poses unprecedented risks. In a letter sent to governments and AI developers, and shared with the media, he said the world was on the cusp of irreversible change that could affect not just current generations but generations of humanity to come.

His intervention comes amid widening debate over the risks of highly capable or “superintelligent” computer systems. A researcher recently resigned publicly from Anthropic, a leading AI firm, over fears that the technology could escape human control. Another Anthropic employee, who did not resign, said publicly that the company sincerely believes AI could kill all humans, and that he thought the chance was greater than 10 per cent within the next decade.

The statements have intensified concerns about the direction of AI development. Anthropic CEO Dario Amodei on Saturday called on AI companies to “pace the frontier” — a proposal for coordinating a slowdown in the development of the most advanced models. His chief competitors, Elon Musk of xAI and Sam Altman of OpenAI, publicly supported the call.

Turk said the world was almost entirely reliant on a small number of powerful companies to make the right choices on AI development for all of humanity. “I call on States and companies to mobilise urgently through multilateral fora to chart a path for action to govern advanced, frontier AI models, grounded in international human rights law,” he said.

The UN rights chief’s letter reflects widening concern that existing governance frameworks are not keeping pace with rapid advances in AI. While AI offers potential benefits in health, education and climate action, it also raises risks related to misinformation, discrimination, surveillance, autonomous weapons and the concentration of power. Human rights law, Turk indicated, must be the foundation for how these risks are managed.

International human rights law already provides standards that apply to AI, including the rights to privacy, freedom of expression, equality and non-discrimination, and the right to an effective remedy. Turk’s letter argues that these standards should guide the design, development and deployment of advanced AI. It also stresses that decisions about AI should not be left only to a handful of companies or states, because their effects are global.

The letter was sent at a time when AI regulation is being debated in several countries and regions. The European Union has adopted an AI Act, while other countries are considering or have introduced their own rules. However, there is no binding global treaty on AI. The UN has hosted discussions on AI governance, including through its General Assembly and human rights bodies, but these processes rely on voluntary cooperation.

The debate over frontier AI has divided experts. Some argue that slowing down development could cede leadership to less cautious actors, and that open research and competition can improve safety. Others say voluntary pledges by companies are insufficient and that binding international rules are needed. The UN General Assembly adopted a resolution on AI in 2024, but it is not legally binding, and negotiations on stronger global governance remain difficult.

Turk’s letter does not propose specific new regulations. Instead, it seeks to push governments and companies to use existing multilateral forums to develop coordinated action. The coming months will show whether the call leads to concrete commitments or remains another expression of concern.
