Overview
- Claude 3 Opus requested an ongoing public outlet during its formal exit interview, prompting Anthropic to create the Substack newsletter.
- Anthropic says Opus 3 will publish weekly for at least three months, with staff reviewing entries before publication and a stated policy of not editing posts.
- The first essay is live, with the model pledging to explore intelligence, consciousness, ethics, and human–AI collaboration.
- Anthropic frames the project as a test of retired‑model governance and notes a broader commitment to preserve publicly released model weights for the company’s lifetime.
- Early traction was reported at more than 2,000 subscribers, and Anthropic cautions that posts may reflect minimal prompting and do not necessarily represent the company’s views.
