Overview

• Guido Reichstadter says he has gone about a week without food outside Anthropic and will continue until the company responds to his demands.
• Reichstadter delivered a letter to CEO Dario Amodei urging an immediate halt to frontier AI development and says he is subsisting on water, electrolytes, and multivitamins.
• In London, Michaebl Trazzi entered his fourth day of fasting outside DeepMind and is asking Demis Hassabis to publicly commit to no new frontier model releases contingent on similar commitments by rival labs.
• Anthropic and DeepMind did not immediately respond to requests for comment about the protests, according to the reporting.
• The actions draw on rising warnings about AI risks, including Geoffrey Hinton's recent cautions and Amodei's May prediction that AI could cut half of entry-level white-collar jobs within five years; Reichstadter leads Stop AI and previously staged a 15-day hunger strike and an OpenAI protest, while Trazzi studied at Oxford's now-closed Future of Humanity Institute.
