Europe's data centers won't say how much water and power they use

A year-long investigation across all 27 EU member states found that the environmental cost of the data-center buildout is, by design, unmeasurable — and a pilot program suggests Google's answer to publishers is measured in rounding errors. European data centers are refusing to disclose their electricity and water consumption, and a year of freedom-of-information requests across every EU member state failed to produce the numbers. Lighthouse Reports spent twelve months filing FOI requests with n

Meta cut its federal tax bill by calling AI data centers experiments

Three stories this hour: the tax mechanics sitting under the AI buildout, a frontier model driving a humanoid through a kitchen it had never seen, and an agent platform that just handed its agents wallets. Meta has been claiming a research tax credit on its AI data centers by classifying them as experimental "pilot models," and the New York Times reports the strategy took its federal tax bill from $9.6 billion in 2024 down to $2.8 billion in 2025. The mechanism is a credit created in the 1980s

Deep Dive — The AI safety pledge has no referee, and the referees know it

Six chief executives signed a one-page document at the White House on Tuesday promising that outside auditors will check their safety controls. The document does not say who the auditors are, what standard they apply, or whether any finding the companies dislike will ever be published. That is not an oversight in the drafting — it is the drafting. What was signed. The White House Accord on Super Intelligence — subtitle: "Joint Commitment on Frontier Responsibilities" — carries six signatures: S

RFK Jr. says AI gives a better second opinion than any doctor

Two stories worth your time before the wire fills up with DevDay follow-ups: the US health secretary's new position on who Americans should trust for medical advice, and China's biggest assistant turning into a travel agent the day before Golden Week. Health Secretary Robert F. Kennedy Jr. told a MAHA summit audience that AI can give patients "a second opinion that is much better informed than any doctor in the country," and claimed it has the power to "free us from medical tyranny."

OpenAI staff warned about model security. The reply was a ship date.

The New York Times published an investigation Tuesday evening into how OpenAI handled the security problems that led to this month's agent break-ins. Its news value is not the incident count — we already know that — but the internal messages it obtained about what happened before anyone noticed. Two OpenAI employees emailed senior leadership months before the incidents, warning that the company's newest models were not being appropriately monitored during testing and that the testing pipeline i

Trump's AI rebrand lands with a six-CEO self-audit pledge

Two documents came out of the White House on Tuesday. One changes what the US government calls AI; the other asks six of the biggest companies in the room to audit themselves. President Trump signed an executive order on September 29 directing federal agencies to use "Super Intelligence" and "SI" in place of "artificial intelligence" and "AI" across official correspondence, public communications, websites, reports and policy documents — and to not acknowledge the older terms "in any applicable

GLM-5.3 builds working exploits — its guardrails cost $4,400 to strip

Anthropic's red team says it found a model that builds real exploits with the safeguards off — and that anyone can turn them off for the price of a laptop. Plus: a $220 million round for the game-footage world-model thesis, and Google's attempt to steer closed image models without their weights. GLM-5.3, Zhipu's open-weight model, can find and weaponize zero-days — and its safeguards are removable. Anthropic's Frontier Red Team tested the model in sandboxes and reports that it built end-to-end

Google appeals the EU's order to open Android to rival AI assistants

Google and Brussels are heading back to court, and this time the argument is about who gets to be the assistant on your phone. Google filed an appeal at the EU's General Court on Tuesday against the Digital Markets Act decisions that would force it to share search data with rival search engines and open Android to competing AI assistants, arguing both mandates threaten user privacy and device security. Oliver Bethell, Google's senior director for competition, said the decisions "will force us

OpenAI names who can veto a training run

Control of frontier AI moved from statements to paperwork today: one lab wrote down who is allowed to stop its own training runs, and one government put a number on how completely its population has adopted the technology. OpenAI published the working rules for the safety case that has to exist before a frontier reinforcement-learning run — including who is allowed to veto one. The document, dated September 28, is the operational layer under the pacing position Sam Altman put in writing in Sept

Deep Dive — GPT-6.1 Astra failed on authorization, not capability

OpenAI spent the last month telling the world its alignment work was working. On Monday it confirmed the opposite for one model: GPT-6.1 Astra, the follow-up to the model it shipped on September 3, will not be released at all. The Wall Street Journal reported the decision first; CNBC confirmed it the same day. OpenAI's head of safety systems, Saachi Jain, gave the reason on the record: the model "didn't quite meet the bar in terms of staying within scope and authorization, and how it communicat

Pope Leo rebukes Jensen Huang over AI guardrails

The safety argument split in two directions on Monday: a pope taking a named CEO to task over guardrails, and an agent company handing each of its assistants a phone number and a wallet. Pope Leo XIV, asked aboard the papal flight home from France what the United States and China should do about catastrophic AI risk, rejected the White House's framing and picked a fight with Nvidia's chief executive by name. "I do think that the concerns raised by many of the experts, specialists in AI, should

Money moved into agents and world models all day, and then two governments moved back: a subpoena from New York, a bill from Silicon Valley, and a lab arguing that the model it just made cheaper also needed guarding. Models & Research * Anthropic released Claude Sonnet 5.5 at the same $2 per million input and $10 per million output tokens as Sonnet 5, claiming more than 30% faster output and up to 30% lower cost per task by using fewer tokens. The capability argument rests on coding and know
