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 Microsoft 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: A moody 1980s neo-noir movie poster of a rain-wet Los Angeles side street at night, a tall storefront window divided into four glowing panes tinted amber, teal, magenta and ivory casting colored light onto black pavement, a matte primer gray 1973 Chevrolet Chevelle Malibu idling at the curb with glowing red taillights reflecting in puddles, a small golden-yellow neon scorpion sign buzzing above the door, 35mm anamorphic grain with soft halation, deep crushed blacks and generous negative space, the words 'Microsoft' handwritten in hot magenta-pink brush script across the upper third of the sky.
This Week in Microsoft News
Summary by Claude Sonnet 5.5 based on this week’s links:
- Open-weight letter: Microsoft hosted a letter urging policymakers not to restrict open-weight models, and Satya Nadella shared it alongside Jensen Huang. Per Andrew Curran, OpenAI, Anthropic, Google and xAI did not initially sign, though he later reported OpenAI had been added to the list on the official site.
- Cyber model claim: Mustafa Suleyman said Microsoft AI's MAI-Cyber-1-Flash, paired with its MDASH multi-agent security harness, scored 96% on the CyberGym benchmark. He said that is 12 points above Mythos at half the cost. This is Microsoft's own claim.
- Small streaming vision model: Microsoft released Mage-VL 4B on Hugging Face, a streaming vision-language model that describes live events as they happen. Users can prompt it to flag a specific moment, such as a train arriving or a goal being scored.
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.
