Today's board finally leaves the terminal. Three of the five hottest repos are about agents producing geometry you can build, print, or move a wall through, and the other two are about giving a whole team — or a whole desktop — a shared agent setup. Pascal Editor (TypeScript, 23,

Three stories from Shanghai's Bund Summit and the Chinese feeds this morning: an energy company's weather model just took the crown on the field's most-cited benchmark, Alipay's assistant started booking real travel, and a Nobel laureate put a number on what

HBM is the stacked memory package that an AI accelerator's processor can read from and write to many times faster than normal RAM — and right now it is the single most expensive, scarcest part of the AI buildout. If you have read that the memory shortage is raising

A memory shortage is now setting the price of Chinese AI compute, and California just created the job of auditing AI. Both stories are about the same thing: inputs and oversight that nobody can source cheaply. Huawei has raised the indicated price of its Ascend 950DT accelerator to more than

DeepSeek's mid-morning release isn't just a new checkpoint. It's a new architecture, an open-weights drop, and a forced migration for anyone still calling its flagship — all in one announcement. DeepSeek released V4.1 Flash on Wednesday, the first model in a new

China's most-watched AI lab spent Wednesday doing two things that pull in opposite directions: quietly hiring the bankers for a Shanghai listing, and publicly retreating from the price increases it imposed three weeks ago. DeepSeek has hired CITIC Securities to prepare an IPO on Shanghai's

Two of the morning's stories come out of the same place: the bottleneck on agentic AI is no longer the model, it's knowing whether the model actually did the job. Alibaba is set to lead a $300 million round in UniPat AI at a $2.5

The first global test scores taken since generative AI went mainstream are in, and they are not the ones the industry has been promising. The OECD's PISA results, released September 8, cover more than 760,000 fifteen-year-olds across 91 countries — and they say the students who

Two OpenAI governance stories landed within hours of each other on Wednesday, and they read better together than apart. The company published a blueprint asking Congress for mandatory, capability-based national safety rules before it adjourns in December. Then it announced that Paul Christiano — the alignment researcher who currently advises

Two things landed overnight: a memory startup with serious money behind a claim that matters to every AI data center, and a computer-vision paper that wants to turn ordinary human video into robot skills. Kepler Computing emerged from stealth with $468 million and a claim the AI industry desperately

Two regulatory threads and one infrastructure bet: Washington is asking whether Nvidia's biggest chip deal was structured to stay under the merger radar, Massachusetts just made data centers pay for their own clean power, and JD.com is building a 100,000-GPU cluster on Chinese silicon. The

Cognition has finally published how its record factorization happened, and the answer is more interesting than the record: an engineer with no expertise in the math pointed a fleet of coding agents at a spare-compute problem and got a world-first in three weeks. Cognition engineer Eric Lu posted
