This week newsletter writers shared Dario Amodei’s “We Must Pace the Frontier” more than anything else. They also linked to Anthropic’s September report on AI misuse and Jacob Coxon’s post saying he’d resigned because Anthropic and OpenAI weren’t acting responsibly. OpenAI’s post on the Navier–Stokes Millennium Prize Problem was widely cited too.

  3. Jacob Coxon on X: "I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below."

  7. Evan Hubinger on X: "Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade. I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to…

  10. Sam Altman on X: "I agree with Dario that we need to pace the frontier. This has been a primary topic of discussions we've had at OpenAI in recent weeks. Committing to having independent evaluators with employee-like access is a great idea, and we will do the same. We'll have more to share soon."

How is this list put together?

Every week Reletter extracts the outbound links from the newsletter issues published across 7m+ newsletters. Links are cleaned up so the same page only counts once (tracking parameters are stripped and redirects unwrapped), then ranked by how many distinct newsletters cited them, so a single newsletter repeating a link cannot push it up. From the top of that ranking we pick ten: the week's biggest story first, then widely shared links on other topics, from politics and the economy to science, sport and the arts.

Why not just show the top of the ranking?

A few subjects take up most of the raw ranking. In a typical week most of the top links are about AI, so a straight top ten would show the same subject over and over. Picking across topics shows the breadth of what newsletters were reading. Every link here was still widely shared, and each one shows how many newsletter issues mentioned it.

What links are left out?

Links from a newsletter to its own site, sharing and subscribe buttons, images and other boilerplate are excluded. So are sponsor links that repeat across most issues of the same newsletter, since those are paid placements rather than citations.

When does it update?

A new list is published every Friday evening covering the week from Saturday to that Friday. Once published, each week is frozen and stays available on its own page.
