Ukraine is selling its battlefield drone footage to AI companies — and nobody's regulating it

Ukraine has become the world's most productive AI training ground, and its drone footage is being sold to fund the war effort. A new MIT Technology Review investigation finds that the country is licensing combat data — videos, telemetry, controller inputs — to commercial AI labs at a scale no laboratory can match. The legal vacuum around what can be done with that data is the next AI policy fight. Ukraine is quietly turning its front lines into a training-data factory, and the world's AI labs a

AI 101 — What is speculative decoding?

If you've ever wondered why an LLM feels slow to type out long answers — or why Nvidia's engineers spent a September 2026 blog post telling model designers how many attention groups to use — the answer is a technique called speculative decoding. Speculative decoding is an inference speedup where a small, fast "draft" model guesses several upcoming tokens, and the big target model verifies them all in a single pass instead of generating one token at a time. The output is bit-identical to what th

Lenovo puts a 120-billion-parameter model on a laptop with Nvidia's RTX Spark

Lenovo unveiled the first laptops built on Nvidia's RTX Spark platform at IFA 2026 in Berlin, and a Chinese robotics lab showed how to keep training a policy while the robot is still working — two stories that point at the same shift: AI is moving off the cloud and onto the box under your hand. Lenovo and Nvidia put a 120-billion-parameter model inside a laptop. At IFA 2026, Lenovo announced the Yoga Pro 9n and the Yoga 9n 2-in-1 — the first notebooks built on Nvidia's RTX Spark silicon, a syst

Huang confirms a $1B Hugging Face retention plan — and rival bidders

Jensen Huang and Clément Delangue sat down together on CNBC's Squawk Box the morning after the deal, and the joint interview answered the questions the announcement blog post did not: what the price was set against, whether the talent is being paid to stay, and how Nvidia plans to explain owning the neutral ground to the labs that compete with it. Huang confirmed on live television that there were other bidders for Hugging Face, and that $12.9 billion was simply the clearing price. "There are o

Tesla opens Cybercab rides in Austin with a 45-car fleet

Autonomy, trade policy, and a détente in Washington all moved on the same day. Here's what landed. Tesla said Thursday it is offering Cybercab rides in "limited areas of Austin, Texas" — the first time the two-seater with no steering wheel and no pedals has carried the public. State records show Tesla had 420 autonomous vehicles registered in Texas as of Wednesday evening, 45 of them Cybercabs, against Waymo's 988 in the state. The launch has been oddly muted: as of Thursday evening Tesla had p

Kurzweil signs on with the brain-computer startup you inhale

Two very different bets on where the interface goes next: Ray Kurzweil has joined a startup trying to skip the skull entirely, and Lenovo just shipped a laptop that keeps frontier-scale models off the cloud. Ray Kurzweil is joining Subsense, a Silicon Valley startup developing a non-surgical brain-computer interface you take like a nasal spray, according to Fortune. Subsense's approach introduces charged nanoparticles into the brain intranasally — the company likens the delivery to inhaling all

DOJ tells a judge that training AI on the news is fair use

The US government has picked a side in the defining copyright fight of the AI era, Tesla finally put its steering-wheel-less Cybercab on the road — quietly — and Oura's IPO filing revealed just how much physiological data one ring company has banked. The Justice Department filed a 20-page statement of interest in the New York Times' copyright case against OpenAI, and it argues model training is not just defensible but "extraordinarily transformative." Filed September 1 in the Southern District

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.

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
