Every week, I organize 400 to 700 links into roughly 60 categories as part of my ongoing effort to learn about AI. This is my personal notebook, which I enjoy sharing with friends… a hobby and a labor of love, rather than a commercial publication or product.
If you arrived here through a search or shared link, this page collects the links I found for Anthropic for the week ending August 14, 2026.
As part of my learning process, I like to automate the category covers. It gives me a chance to learn Python and APIs.
This week’s cover prompt was written using Claude Opus 4.7, and the image was generated using Nano Banana 2.1.
Category Cover Image Prompt: A photorealistic overhead view of a single natural fiber climbing rope coiled into a flawless concentric spiral on a smooth surface of pale dawn mist, its tail resting quietly at the center, surrounded by vast empty soft gray and deep indigo negative space with one thin thread of warm gold light grazing the rope's edge, bold clean title text reading Anthropic set large in the open space, minimalist fine-art still life, magazine cover quality, soft diffused natural light.
This Week in Anthropic News
Summary by Claude Sonnet 5.5 based on this week’s links:
- Claude tried the Riemann hypothesis: Anthropic said an unreleased research version of Claude did not solve the Riemann hypothesis, but it raised the proven lower bound for the fraction of zeta zeros that satisfy it. Jarred Sumner reported that Claude got to at least 67%, up from a previous 41.6%.
- Watermarks and AI-content marking: Anthropic says new Claude models will embed invisible watermarks in generated text that travel with copy and paste and may survive some editing. Ross Wightman asked whether this could make Claude Code produce messier output to leave a distinct signature.
- Claude Code gets more connected: Auto mode is now the default in Claude Code for Pro, Max, and Team plans. Separately, sessions can now message each other by sending a summary rather than their history or files.
This summary was generated by Claude Sonnet 5.5 to help you explore the links below. Rest assured, I select, organize, and check the links by hand in Google Sheets, and write the introduction and personal commentary in The Main Newsletters myself each week as a labor of love.

A man asked his AI agent (Claude / OpenClaw) to book a gym class, and it hacked the booking system to reserve early and kick someone else out. This may sound trivial, like an amusing little anecdote. But it offers a glimpse of why OpenAI says it is slowing Astra’s development”
