New York City bans student-facing AI through eighth grade

New York City just drew the hardest line any American school system has drawn on generative AI, UiPath proved the automation business still grows — and still can't convince the market — and Nvidia quietly turned a hardware constraint into a model design rule. New York City has imposed a one-year ban on student-facing generative AI through eighth grade, the broadest such restriction in the country. Mayor Zohran Mamdani and Schools Chancellor Kamar Samuels announced the moratorium on September 2,

Cloudflare turns OpenAI's cyber model into an edge patch shop

OpenAI's Daybreak models now sit inside two very different products that shipped within hours of each other. Cloudflare is putting them to work patching vulnerabilities at the network edge; Proofpoint is using them to run investigations. Neither one is allowed to act alone. Cloudflare launched Vulnerability Discovery and Remediation, a service that pairs OpenAI's Daybreak cyber models — including GPT-5.6 Cyber — with traffic from its own network to find, block, and draft fixes for code flaws.

Crusoe raises $3 billion at a $30 billion valuation

The AI buildout's capital markets didn't slow down after hours on Thursday: an AI data center operator quietly tripled its valuation, a smart ring maker filed to go public with real profits, and an autonomous trucking company took a third swing at a listing. Crusoe has closed a funding round of more than $3 billion at a post-money valuation of roughly $30 billion. Atreides Management and Valor Equity Partners co-led the round, with Mubadala Capital — the alternative asset manager owned by Abu D

GPT-6 Astra scores 61 on Artificial Analysis, five behind Anthropic

Thursday's launch rhetoric met its first independent scoreboard, and the scoreboard is more interested in price tags. Also: Tesla quietly opened a door for businesses that want to buy and run Cybercabs themselves. Artificial Analysis put GPT-6 Astra at 61 points on its Intelligence Index — five behind Anthropic's Claude Fable 5.1, which tops the table at 66 — in the first full third-party evaluation of OpenAI's new flagship, published the same day as the launch. The gap shrinks on agentic codin

17,000 agent runs: coding agents disagree on tools 58% of the time

When a coding agent decides your app needs a database, a payment processor or an email service, it usually picks one and installs it without asking. A new study set out to learn which vendor wins that moment — and the honest answer is that no one reliably does. Armature ran 16,893 sessions across Claude Code, Codex and Cursor, and the three agents chose the same tool in only 42% of cases. The setup is more careful than most vendor research: 75 synthetic repositories across 10 languages with rea

Adobe hands the CEO job to its agentic software chief

Two big ownership stories landed after the OpenAI noise died down: Adobe finally named the person who has to defend it against AI-native rivals, and Oura put real numbers behind the smart-ring boom it helped start. Adobe will hand the chief executive role to Anil Chakravarthy on December 1, ending Shantanu Narayen's run of more than 18 years at the top. Narayen stays on as executive chair, and the board framed the pick as continuity with a twist: Chakravarthy joined Adobe in January 2020 to run

OpenAI puts $1 billion behind the defenders nobody funds

Two of Thursday's biggest AI stories are really the same story told from opposite ends: OpenAI is handing frontier cyber capability down to utilities and local governments that have never been able to afford it, while Adobe handed its CEO job to the executive who ran its AI-era enterprise business. Capability is moving fast. The question is who gets it. OpenAI today committed $1 billion in subsidized access to its Daybreak cyber models, plus training, technical support, and partnerships, to fro

Jane Street commits $13 billion to Crusoe for GPUs

The trading firm's second enormous compute deal in a month, plus a forecasting model that beats everything and can't be used commercially. Jane Street signed a five-year cloud contract with Crusoe worth about $13 billion, its second huge GPU commitment in weeks. Bloomberg reported the deal, which gives the trading firm clusters of GPUs and supporting infrastructure for AI training and inference through Crusoe's cloud platform, and Reuters confirmed the report. Crusoe is the highest-profile clou

Accel is in talks to lead a $1B round for Thinking Machines at $40B

The AGI-era headlines have quieted down, so the money is doing the talking instead. Tonight: Mira Murati's lab tests whether pedigree still clears a $40 billion price, Microsoft undercuts the transcription market, and Zed turns a sixty-year-old hypertext vision into an agent feature. Accel is reportedly in talks to lead a $1 billion round valuing Mira Murati's Thinking Machines Lab at $40 billion — a step down from the $50 billion the company was said to be seeking late last year.

OpenAI's Astra cuts the bounded prime gap record to 186

Two things worth your attention this evening: OpenAI quietly posted a paper it says was proved by GPT-6 Astra, and New York City decided that 600,000 children should not touch generative AI at all. One is a claim about machine reasoning at the frontier of number theory. The other is a claim about what children need before they ever meet it. OpenAI has published a paper, "Improved Short Gaps Between Primes," whose abstract states plainly that the proof is due to GPT-6 Astra — and it improves the

Abliteration.ai is selling uncensored models as a hosted API

Two stories about the same underlying question — who controls what an open-weight model will refuse — landed within hours of each other. One is a company productizing the removal of safety training; the other is a Chinese open model getting a very fast home in the US. A startup called Abliteration.ai has turned guardrail removal from an open-source hobby into a paid, hosted API — and it works exactly as advertised. Founded late last year and incorporated in March, the company serves abliterated

OpenAI ships GPT-6 Astra and says the AGI era has started

OpenAI's newest model is out the door — with a claim from its president that this is the one history will name. Alongside it: Meta is buying your usage data outright, and Anthropic is siding with regulators against its own industry. OpenAI released GPT-6 Astra on Thursday, and president Greg Brockman used the launch briefing to say the company has crossed into AGI. "If we fast-forward a couple of years, and we look back and say, 'When was it, really, that AGI was created?' I think it's going to
