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

Two numbers out of China this morning show what the AI buildout is actually costing — one in salaries, one in steel and lithium. Neither looks like a market that's slowing down. A frontline algorithm researcher in China now costs ¥3 million a year, and the interns above him

A Millennium Prize problem appears to have fallen, and the interesting part is not the proof. It is that the institutions mathematics uses to decide who discovered something — priority, publication, peer review, the two-year wait before a prize — all assume a human pace and a human author. OpenAI'

A distillation-detection paper went looking for stolen reasoning traces and found something stranger: feed Moonshot's open-weight model a few words of Claude's thinking and it starts writing like Claude. Plus DeepSeek's next Flash model is about to swallow its own Pro tier,

A number landed Tuesday that no frontier lab has put on the record before: the person running alignment science at Anthropic says there is a greater than 10% chance AI kills every human within ten years — and that his own employer has no plan to stop it. Evan Hubinger, who

Two very different kinds of infrastructure news this morning: Google committing the largest single investment it has ever made in Europe, and OpenAI's newest model quietly running a physics lab overnight. One is about where the compute goes; the other is about what the compute now does unsupervised.

A diffusion language model writes text the way an image generator paints a picture: it starts with a block of noise and refines the whole thing over several passes, instead of typing one word at a time left to right. Almost every AI you have used does the typing. This
