Angle Health raised $600M to underwrite small-business plans with AI

Two funding rounds and a policy fight today: an AI-native insurer takes on the small-group market, Europe's own AI firms tell Washington to stop pretending the slowdown is about safety, and the data-loss-prevention business gets rebuilt for agents. Angle Health raised $600 million led by Vitruvian Partners at a $2.7 billion valuation, and the pitch is narrower than "AI in healthcare": it is algorithmic underwriting for the employers nobody wants to cover. The company sells full-stack health pla

Google gives CC its own account to run a six-person household

Google Labs stopped treating its CC agent as a personal assistant and gave it a seat at the family table — with its own Google account and its own permissions model. Google Labs is testing a new version of CC that runs a household rather than an individual, and the mechanism is the story: the agent gets its own Google account, a distinct identity, and a permission set that up to six family members negotiate with it. Google says the pivot came from user requests — people wanted help with school

Claude Code now reads AGENTS.md — and makes its harness rewritable

Anthropic conceded the file-format fight this week, then quietly shipped something larger underneath it: a plugin layer that lets anyone — an organization, a vendor, a person — rewrite how Claude Code behaves at the hook level. Version 2.1.277 of Claude Code now loads AGENTS.md as project instructions in any project that carries no CLAUDE.md of its own, with a setting to flip it to "load both" or "ignore the shared file entirely." The same release publishes the source of the mechanism behind it

Virginia ends by-right approval for big data centers

Virginia just made itself the hardest US state to build a data center in. Governor Abigail Spanberger signed Executive Order 22 alongside a "Data Center Accountability Framework" that ends by-right approval for any facility drawing more than 25 megawatts, pulls large data centers out of the state's fast-track permitting, bars executive-branch agencies from signing NDAs on projects, and ends site-development subsidies for the industry. In the state that hosts the world's densest concentration of

Newsom orders a kill switch and onsite auditors for frontier AI

California Gov. Gavin Newsom signed an executive order Friday that tells his own agencies to design the state's next round of AI rules — and names the two things the industry has resisted hardest: a kill switch for frontier models, and independent auditors embedded inside the labs. Executive Order N-9-26 gives the Government Operations Agency until November 16, 2026, to deliver recommendations on four specific mandates, and each one aims at the same target. Frontier developers would have to hos

A chatbot almost sent US troops onto a Chinese ship

The AI risk debate has spent the week on model weights and pacing pledges. Today it produced something the argument kept promising and never showed: a real near-miss where an analyst's chatbot, not a model's inner life, put an armed boarding party on a launch path. A US military intelligence report that claimed a Chinese ship in the Middle East was carrying components of a nuclear weapons program was built with the help of a chatbot — and was "entirely false," according to CNN, which spoke to f

Sony and UMG sue Suno over its label-backed v6 model

Two of the three majors are still at war with the AI music company that just signed up their rivals. Sony Music Entertainment and Universal Music Group filed a new 45-page lawsuit against Suno in the US District Court for the District of Massachusetts, arguing that the company's licensed v6 models infringe their copyrights because they were trained on the outputs of the earlier, unlicensed ones. The labels' theory is blunt: Suno has acknowledged that v6 was built partly on the products of its p

Over 100 AI experts attach conditions to the labs' evaluator pledge

The people who would do the auditing just told the labs what independence has to mean — and one of their conditions is protection from being sued for it. More than 100 AI researchers and evaluators published a letter Friday setting minimum conditions for the third-party evaluation that Anthropic and OpenAI have promised, with signatories including Geoffrey Hinton, researchers from Johns Hopkins and Stanford, and staff at the nonprofit evaluator METR. The letter was organized by the AI Evaluator

The Take — Breaking Mila's windows is a gift to the labs

I think the people who smashed roughly 20 windows at Mila this week did more damage to the case against AI than to the institute — and that the labs they were angry at are the ones who benefit from the mess. Start with what actually happened, because the details decide the politics. Late Tuesday night, about 10 people broke windows and spray-painted graffiti at the Montreal offices of Mila, the institute Yoshua Bengio founded, hours before the city opened ALL IN, billed as Canada's largest AI a

Protesters broke Mila's windows on the eve of Canada's biggest AI summit

The AI backlash stopped being a polling number this week. In Montreal it smashed about 20 windows, and by Wednesday evening police were pulling people out of a march outside the country's largest AI conference. Hours later and 4,000 km away, California put a kill switch on the agenda. About 10 people smashed roughly 20 windows and spray-painted graffiti at the Montreal offices of Mila, the AI institute founded by Yoshua Bengio, late Tuesday night — hours before the city opened ALL IN, billed as

React's creator closed Conway's 50-year-old conjecture with AI

The most interesting AI proof of the year did not come out of a lab. It came out of a software engineer's chat subscriptions, a swarm of agents he admits he didn't understand, and a Lean repository anyone can check. Dan Abramov, co-creator of React, says he proved Conway's refinement conjecture — an open problem John Conway posed 50 years ago in On Numbers and Games — using a self-built laboratory of AI agents that he steered mostly on instinct. He was not being modest when he wrote that he is

AI out-persuades experts by volume — and pays in accuracy

Science has been running a feature on why chatbots are so good at changing minds — first posted in late August, back on the Hacker News front page today — and the primary papers underneath it are less flattering to the models than the headline suggests: they win on throughput, and the field's own numbers say the win is bought with truth. The research line behind the coverage is the strongest measured persuader against humans in the literature, and it is no longer theoretical. Here is what the p
