What actually happens when Claude analyses a financial document for errors? I gave Opus 4.6 a deliberately broken pitch deck: 21 pages of PDF, a backing Excel model, and a DOCX earnings report. It found 40 issues including formulas that drive PP&E negative

For all my lifters: computer vision app to measure back curvature during deadlift! main technical highlights: — RF-DETR (Roboflow) to segment the person (great performance out-the-box with no additional training!) — YOLO11n (Ultralytics) for bounding box prediction around the barbell weight plate (trained on my own small dataset). — Mediapipe (Google) for pose landmark detection to guide the bounds for the line fitting. — Custom logic to fit a line across the back. about the plots on the right side: The Back Roundness Map shows the deviation of the estimated back curve from a line of best fit.

Gemini 3 Deep Think generated a real-time 3D WiFi radar that maps every network around you as glowing nodes in a Matrix-style space — in one shot. It used Pearson correlation to infer which APs are physically close, since RSSI alone isn't enough.

This will be so awesome 🤩
SpaceX is now shifting their priorities into building a Moon Base - doing so in less than a decade. This proposal from the ISU involves converting a Starship into a lunar base, Skylab-style. Starship’s ~1000m^ 3 of pressurized volume would result in a copious base.

Agents will become a common way people shop. So today we are releasing 3 tools to make adding commerce to those agents trivial: - Checkout Kit: embed commerce widgets and checkout(!) directly into your agent and chat. This is already being used by Microsoft’s @Copilot. - Shopify Catalog: low latency global product search across millions of merchants - Universal Cart: shop from any store, anywhere, in one cart With these, you can build seamless embedded commerce experiences quickly, starting with all the best products by the best merchants in the world instead of having to sign them all up individually. No need to build a complex new checkout, or dealing with regulatory marketplace rules. Commerce just plugs in and feels seamless in conversations. We believe commerce should be everywhere people are, so we’re making that as easy as possible for the AI age.

If you look closely, you can see a human walking around the base of the rocket. Each Raptor rocket engine produces twice as much thrust as all 4 engines on a 747. There are 33 Raptor engines powering the Starship rocket booster.

The OSWorld benchmark tracks how well AI models can use computer programs. I've been watching this closely, because when AI gets good at this, many new startup ideas become viable. The top scoring model went from 7% to 22% yesterday.
