Anthropic publishes a paper/blog post titled 'When AI Builds Itself', detailing how AI systems (e.g. Opus 4.7 helping build Opus 4.8) are increasingly used to develop their own successors, with compute framed as the primary remaining bottleneck. Coverage includes an associated biosecurity letter from AI lab leaders and a proposal for a global pause on frontier development, published around the same time as Anthropic's confidential IPO paperwork.
