Following Dario Amodei's "We Must Pace the Frontier" essay (endorsed by Sam Altman and Elon Musk) and reports that Anthropic, OpenAI, and Google DeepMind have held working-group talks since July on an industry-led AI safety standards body, President Trump forcefully rejected the idea of a coordinated slowdown, saying the only AI guardrail needed is "a strong and smart president" and that "whoever wins AI wins." Coverage frames this as a direct clash between the labs' safety push and the administration's accelerationist stance.
Sam Altman's public endorsement of Amodei's slowdown essay put OpenAI alongside Anthropic and Google DeepMind in Trump's rebuke (see Anthropic above). No separate OpenAI product news of note in this window; the IPO-delay-to-2027 story from Sep 12 remains the latest business development.
Bilal Chughtai, who worked on AI safety and alignment at Google DeepMind, announced his resignation Monday with public posts on X and LinkedIn warning that humanity is running out of time to prevent AI from causing widespread harm. The post lands the same week Google DeepMind joins Anthropic and OpenAI in the reported industry safety-body talks (see Anthropic above).
No significant updates today. Grok's addition to Copilot (Sep 12) remains the latest development, already covered in a prior briefing.
xAI's three-day "Grok Bot Galaxy" event begins today at The Howard in San Francisco with a parallel livestream, showcasing Grok Bot on real workflows with role-specific sessions for engineering, product, sales, support, and marketing. Grok 4.7 remains delayed with no new ship date; Grok 4.6 (Aug 12) is still the latest shipped model.
Nvidia's AI Infra Summit runs today through Sept 17 at the Santa Clara Convention Center, with VP Ian Buck keynoting on full-stack AI-factory infrastructure (Vera Rubin NVL72, Vera CPU, Spectrum-X Ethernet, BlueField-4). Separately, Nvidia announced it's expanding land, power, and shell capacity with Australian cloud partners to host multiple generations of its DSX AI systems. No update on the previously reported talks around a possible ~$10B anchor stake in Anthropic's IPO.
No significant new deals reported today. The existing pipeline — Meta's Vistra/TerraPower/Oklo/Constellation agreements (up to 6.6GW), Microsoft's Three Mile Island restart, Google's Kairos Power SMR order, and Amazon's Susquehanna/Talen campus — remains the latest state of play, already covered in prior briefings.
No significant new developments today beyond the already-covered SpaceX/Anthropic AI1 orbital-compute constellation filing, Starcloud's in-orbit AI training milestone, and Orbital's 100,000-satellite FCC filing. See the Space Weekly Briefing for fuller company-by-company coverage.
