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 X for the week ending August 21, 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: Realistic architectural photograph of a 1929 Indiana limestone Art Deco skyscraper in Manhattan, shot from across the street in bright direct sunlight with crisp raking shadows and a clear deep blue sky, showing a setback with three identical stylized herms emerging from vertical piers between dark steel-framed windows, each herm holding a geometric Deco megaphone against its chest with a carved relief frieze of overlapping speech bubbles cascading beneath them, the word TWITTER incised in large Art Deco capitals into a limestone frieze band above an entrance, warm honey-cream stone, neighboring buildings receding behind, perspective-corrected verticals.

Summary by Claude Sonnet 5.5 based on this week’s links:
Cursor announced it is now part of SpaceX, according to a post on Cursor's own blog. A separate post teased that Elon Musk is making another move, framed as a challenge to Codex and Claude Code.
On the benchmark side, Vals AI reported that Grok 4.6 ranks #3 of 49 on its Legal Research Bench at 48.1%, at a fraction of the price of the two models ahead of it.
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.
