1,224 AI Workers Call for Capacity to Pace Frontier Development
More than 1,200 employees at frontier AI companies, including Anthropic CEO Dario Amodei and senior scientists at OpenAI and Meta, are urging the US to help build an international capacity to “deliberately pace” AI development. The petition does not call for an immediate slowdown; it argues that automated AI research could accelerate capabilities beyond existing security and oversight, while competition leaves individual companies and countries unable to act alone. Bloomberg AI editor Seth Fiegerman says the group is seeking a mechanism to slow or interrupt development if necessary, without specifying who would wield it or when.
OpenAI Takes GPT-5.6 Global After U.S.-Reviewed Limited Preview
Bloomberg’s Seth Fiegerman reports that OpenAI is moving GPT-5.6 from a limited, government-shaped preview to global availability after pressure from the Trump administration to stagger the release. The model family is aimed at coding, cybersecurity and enterprise use, but Fiegerman says it remains unclear what changed between the restricted rollout and the wider launch. OpenAI argues the review process should not become the default for frontier-model releases, even as Washington scrutinizes systems with stronger cyber capabilities.
Anthropic Seeks $30 Billion at More Than $900 Billion Valuation
Bloomberg’s technology program framed the day’s AI trade around access to scarce capacity: Nvidia chips for China, private capital for Anthropic, and manufacturing scale for Anduril. Its central report was that Anthropic is in early talks to raise at least $30 billion at a valuation above $900 billion, a deal Bloomberg’s Natasha Mascarenhas said would mark a major shift in the private AI hierarchy if completed. The program also treated Jensen Huang’s last-minute role in Trump’s China trip as a test of whether chip access can become a diplomatic deliverable without undermining Beijing’s domestic semiconductor strategy.
Compute Supply, Power, and Capital Are Defining the AI Buildout
Arm’s warning on smartphone weakness sat alongside a stronger claim from chief executive Rene Haas: handset softness is concentrated in lower-end devices, while data-center demand is accelerating because agentic AI workloads need CPU orchestration. Bloomberg Technology’s May 7 program used that contrast to trace a broader AI-infrastructure market in which demand is less in question than the ability to secure compute capacity, power, supply chains and capital. Anthropic’s lease of SpaceX compute and CoreWeave’s financing questions pointed to the same constraint: available infrastructure, not appetite for AI, is becoming the limiting factor.
