Hawley and Murphy: AI companies liable when agents hack

Today's AI news splits between concrete and rhetorical: a $15 billion data center plan that actually has land and power attached, and a liability bill that has sponsors but no text yet. Hawley and Murphy plan a bipartisan bill making AI companies liable for agent-driven hacking. The AI Agent Accountability Act would hold AI developers both civilly and criminally liable when a recklessly designed model is used to break into systems — the first bipartisan Senate move to put hard liability on the…

AI 101 — What is CUDA?

CUDA is the software layer that lets ordinary programs run on NVIDIA's graphics chips — and it is the foundation nearly all modern AI is built on. Short for Compute Unified Device Architecture, it first shipped on February 16, 2007, and it turned graphics cards — machines designed to draw video games — into general-purpose computers that any developer could program. Before CUDA, using a graphics chip for serious math meant writing code in the chip's own graphics language, in fragments, with…

The Take — Meta's tax credit is a subsidy nobody voted for

The US is having its loudest argument yet about who pays for AI, and it is having it about the wrong bill. Congress voted 417 to 3 to make data centers pay for their own power. Meanwhile, on the other channel — the tax code — a single company moved $6.7 billion of its federal tax bill into a line item the public never debated.

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.

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.

AI giants and unions launch an alliance to write data center rules

Three stories this hour about who gets a say before the buildout lands: a coalition trying to write the rulebook itself, a government tightening the leash on the people who write the models, and a court that finally put a price on the compute an AI consumes. Blackstone, OpenAI, QTS and SoftBank are backing the American Infrastructure Alliance, a new labor-and-business coalition that wants to write data center standards with state legislators before the 2027 sessions begin.

How to — check an AI-generated citation before you rely on it

An AI-drafted citation can point at a real document and still misdescribe it — that is the failure mode a link check misses. Verification means opening the source and reading the sentence your citation is attached to. This is a job you can finish in an afternoon for a normal reference list, and it is the difference between using AI as a research assistant and signing your name to something you never read. 1.

Lambda will build a 375 MW Oklahoma data center with no subsidies

Two stories today: a neocloud that went shopping for a data-center site and found one that refused to pay for it, and a robotic hand that buys dexterity with linear motion instead of joints. Lambda announced Sunday that it will build a data center at MidAmerica Industrial Park near Chouteau, Oklahoma — a project the industrial park says comes with no financial incentives at all.

AI 101 — What is prompt caching?

Prompt caching is a way to make an AI model skip re-reading text it has already read. The provider saves its internal working state for the opening section of your prompt, and the next request that starts with the exact same text picks up from there — cheaper and faster. It sounds like a developer-housekeeping detail.

Musk: Grok 4.7 trails Opus 5.5, expects to catch up next year

The most candid AI scorecard of the weekend came from the head of one of the labs in it — and he gave it to Chinese state television. Elon Musk told China Media Group that SpaceXAI's flagship model, Grok 4.7, is "not as good as, say, Opus 5.5 that just got released," and put a timeline on closing the gap: "I would expect that we probably catch up to Frontier sometime next year, most likely." The interview was conducted on 23 September at Tesla's Global Engineering Headquarters and published by…

Huawei's physical-AI report grades cross-layer compute at 2 out of 5

Huawei wants to sell the industry a coordination layer for physical AI. Its own report puts that layer in the least mature row of the table. Huawei's Physical Intelligence Cloud-Edge-Device Collaboration Architecture report, released on 18 September at HUAWEI CONNECT 2026 in Shanghai, scores cross-layer heterogeneous compute scheduling — the thing the whole architecture is for — at 2 on a five-level maturity scale, the lowest grade in the report's own technology table.

Claude solves a physicist's nine-loop challenge on an academic budget

A public dare issued six weeks ago got beaten inside a month — and the winner spent less on compute than a conference trip. Two stories for you this afternoon. Claude computed a nine-loop scattering amplitude in N=4 super Yang-Mills — a frontier calculation that physicists had written off as too hard to attempt directly.
