The signal

  1. Amodei calls for a coordinated AI slowdown, Altman and Musk back him, OpenAI rules out a 2026 IPO What happened: Dario Amodei published an essay, “We Must Pace the Frontier,” proposing a three-part plan (permanent embedded third-party evaluators like METR with employee-level access, industry-wide coordination on safety standards and pace limits, then coordination with China and other states); Anthropic is unilaterally committing to step one. Sam Altman said “I agree with Dario that we need to pace the frontier” and OpenAI will match the evaluator-access commitment; Elon Musk said “Dario is right.” Separately, Altman told Fortune a 2026 OpenAI IPO would be “ill-advised” given the safety and alignment work underway. Why it matters: this is the first time the three most prominent frontier labs have publicly converged on slowing release cadence and opening internal access to outside evaluators. It changes how these models get checked before shipping, not just how they get marketed, and it directly reshapes the OpenAI IPO timeline.

  • Altman’s Sept 11 internal comments about being open to slowing development went public and turned into a concrete commitment: OpenAI will give third-party evaluators employee-level access, matching Anthropic’s move TechCrunch (independent)
  • Over 1,300 employees across Anthropic, OpenAI, Google DeepMind, and Meta have now signed onto the pacing push, per The Hill’s count The Hill (independent)

Other

  • Pentagon’s Office of Strategic Capital is in talks to lend AI cloud startup Fluidstack roughly $5B to shore up US datacenter supply chain and component manufacturing, per WSJ; deal not finalized Data Center Dynamics (independent)
