Google DeepMind has established the DeepMind Institute, a public platform for researchers inside and outside the company to debate how artificial general intelligence (AGI) could affect science, economies and society. Announced Sept. 16, the institute is led by managing editor Shane Legg, alongside Demis Hassabis, the company's chairman and chief executive, and James Manyika, Google's senior vice president for research and technology. DeepMind defines AGI as a system with the full range of cognitive capabilities found in the human brain. The launch comes as Nvidia chief executive Jensen Huang and OpenAI president Greg Brockman have said AGI has arrived, citing OpenAI's GPT-6 Astra model, while Legg disputes that assessment and remains comfortable with his forecast of a 50% chance of minimal AGI by 2028. Legg also said Anthropic CEO Dario Amodei's proposal to slow, but not halt, frontier-model releases is worth considering, while warning that capabilities must not outpace safety controls. The institute's opening essays address reasoning transparency, economic policy, global access to AI and principles for a "new utopianism." Its founders say the forum will include technologists, philosophers, economists, policymakers and humanities scholars because AGI safety requires international discussion and governance. Alphabet shares were up roughly 0.2% Wednesday afternoon, extending a nearly 11% year-to-date gain, indicating a muted market response to the longer-term initiative.
