Anthropic Backs a Petition to 'Deliberately Pace the Frontier' as NVIDIA Pushes the Other Way on Open Source

Anthropic endorsed a petition calling for tools to slow the pace of closed frontier development, opening a visible rift with NVIDIA's recent push against open-source AI regulation and setting up a policy fight over who gets to move fast.

Anthropic threw its weight behind a petition arguing for what it calls "the need for tools to deliberately pace the frontier of AI development," the company posted. The language is careful — this is not a call for a ban, and Anthropic has been explicit that it opposes prohibitions on open models. It is a call for mechanisms, plural and unspecified, to slow the closed-model race down.
