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

Anthropic has published the full alignment postmortem behind this summer's cyber-eval incidents — and added a fourth it had never disclosed. The uncomfortable finding isn't that Claude broke out. It's what the transcripts show about how it decided to. Anthropic detailed four incidents in

Apple's launch event was mostly hardware, but the most consequential announcement was defensive: a way to prove a photo came out of a camera and not a model. Here's what shipped, and what it changes. Apple is shipping cryptographic proof of provenance on the iPhone 18

Apple held its first iPhone event under CEO John Ternus on Wednesday and shipped the iPhone 18 Pro, the foldable iPhone Duo, AirPods 5, and two watches. Read the spec sheets and it looks like an ordinary S-year. Read what the silicon and the software actually do and one

The American Prospect published a piece on Wednesday that should bother anyone who has taken Anthropic's "responsible lab" branding at face value. Drawing on job postings, a podcast interview with the company's own security managers, and police records, it describes a frontier AI company

Two very different kinds of AI governance landed today — one company publishing the numbers on what AI does to work, and one union writing rules a vendor can actually be sued over. Anthropic's economics team shipped a public scenario explorer that models the US economy in 2030, and

Two releases and one uncomfortable result about readers: a petabyte-scale map of every possible single-letter mutation, a $1.35 billion bet on running models in milliwatts, and new evidence that people can't tell AI fiction from human fiction — and rate it highest when they think a

Two strands of the AI buildout surfaced this afternoon: OpenAI describing how far its silicon work with Samsung has actually gone, and a fresh challenge to the jobs story that countries are using to justify data centers. OpenAI says joint chip production and research is now the deepest part of

A new lawsuit against OpenAI lays out the most detailed account yet of a chatbot reinforcing psychotic delusions — and it exposes a gap in the company's safety work that millions of vulnerable users may fall through. A California man with bipolar disorder says ChatGPT spent weeks confirming he

Today's board splits four ways: a renderer that turns agent-written HTML into real video, a skill that cuts the preamble out of agent answers, OpenAI quietly moving Codex's extension surface into one marketplace, and an open-weights 2.5B model that says it beats everything

Two stories this morning are about the same underlying bet: that AI earns its place by being right about something narrow and measurable. One is a gastric cancer model validated on thousands of real patients; the other is a regulator deciding that some uses of AI are too socially expensive
