Two stories about the layer underneath the models: the agent that now plans the observation, and the memory the whole stack is short of. Alibaba says its Qwen Office agent helped a research team at the National Astronomical Observatory of China build a large-aperture, research-grade telescope simulation system

A security startup used one lab's newest model to walk into its rival's internal code repositories, and did it in under three days from first probe to finished chain. The mechanics are worth reading. The economics are the part that should change how you budget. Hacktron

Medical imaging AI has been stuck for a decade: one disease, one model, a radiologist labeling every slice by hand. A paper in Science this week argues the generalist route is the one that actually scales. Alibaba's Damo Academy has published a generalist radiology model in Science that

Temperature is the setting that controls how randomly an AI model picks its next word: near 0 it always takes the most likely word, higher values give unlikely words a real chance, and 1.0 is the default on most APIs. It is the first knob most people turn, and

An unnamed checkpoint appeared on the Arena leaderboard this week, and the AI world has already decided what it is. The evidence is thinner than the excitement — which is exactly why the story is worth reading carefully. A model carrying the name "gemini-3.8-flash" is competing

Two gaps got money and code this week: science still has no compiler, and the next generation of AI chips still has no common language. Keli Xinxu, an AI-for-science startup founded by an assistant professor at Hong Kong University of Science and Technology, has raised nearly 50 million

Two answers to the same question landed a day apart: how much compute is actually coming. One is a shipment forecast from the company selling most of it, the other is a hardware announcement from the one building it without American parts. Jensen Huang says Nvidia will sell twice as

Two stories about the same thing from opposite ends: a security firm used one lab's models to break into its rival, and a coding agent got a feature for finding what the humans never got around to looking for. Plus a local-inference release that argues the number

Two government deployments landed in the same week, and both were built on the same admission: the models aren't good enough to be trusted alone yet, so the humans stay in the loop. Also this morning, a bilingual safety benchmark that complicates the way labs market their multilingual

A year-old AI accelerator is appreciating like real estate, not like a graphics card. That changes what gets borrowed against it — and what it says about the shape of the boom. Nvidia's B200 is trading at 158% of its launch price roughly a year after it reached

Waymo's international expansion added a fourth flag today, and this one lands in a country that has already legislated for the drivers it might displace. Waymo will launch a commercial robotaxi service in Singapore by 2028, its first market in Southeast Asia, working with the Ministry of Transport

A zero-click remote code execution flaw has been found in all four major AI coding agents — and the part that should worry enterprises is that doing everything right does not defend against it. Air, a security startup that guards enterprise AI agents, disclosed Plugin4Shell on September 17: a flaw
