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 Perplexity for the week ending July 31, 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 Gemini 3.1 Flash Image Preview.
Category Cover Image Prompt: Cinematic 1980s neo-noir movie poster interior shot of a 1973 matte primer gray Chevelle dashboard at night, a glowing unfolded paper map on the passenger seat with branching inked routes converging on one circled destination, pinned by a small golden-yellow scorpion paperweight, an anonymous gloved hand on the steering wheel, sodium-vapor amber and deep teal light bleeding through the windshield onto wet asphalt beyond, 35mm anamorphic grain with soft halation and crushed blacks, the title Perplexity scrawled in hot magenta-pink handwritten brush script in the lower third.
This Week in Perplexity News
Summary by Claude Sonnet 5.5 based on this week’s links:
- Computer grows into a workspace: Perplexity launched Projects on Computer, replacing Spaces with shared hubs that have persistent memory and a common file system. Personal Computer also arrived in the Windows app as a local agent harness across files, apps, and the web.
- Security for agents: Perplexity open-sourced Numbat, a detection layer that shows security teams what agents are doing and can block chosen actions before they run. Aravind Srinivas also said Perplexity is joining the OSAA, citing Hugging Face's breach, where open-weight GLM 5.2 ran on its own infrastructure.
- More models and tools: Model Council in Computer runs several frontier models independently and returns one cited report on where they agree and differ. Perplexity also released a CLI so coding agents in any harness can use the web, and added Kimi K3 for Pro and Max subscribers, hosted on U.S. servers.
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.

When Hugging Face got breached, the closed tools couldn’t distinguish attackers from defenders and blocked the forensic analysis. They ended up running open-weight GLM 5.2 on their own infra to contain it. Perplexity is joining the OSAA to support open tools for security.”

Today we’re open-sourcing Numbat, an agent-detection and response layer that is designed to work across agent harnesses. Numbat gives security teams visibility into agent activity, with controls to block selected actions before execution. Read more:”

Model Council is now available inside Computer. Run independent analysis across multiple frontier models, choose your analysis depth, and get a single cited report on where models agree, where they disagree, and what each found that others missed.”
