DOJ probes whether Nvidia's Groq deal dodged antitrust review

Two regulatory threads and one infrastructure bet: Washington is asking whether Nvidia's biggest chip deal was structured to stay under the merger radar, Massachusetts just made data centers pay for their own clean power, and JD.com is building a 100,000-GPU cluster on Chinese silicon. The Justice Department is investigating whether Nvidia structured its licensing deal with AI chip startup Groq to avoid antitrust scrutiny, the New York Times reported, citing two people familiar with the matter.

Devin factored RSA-260 on spare GPUs — for about $400,000

Cognition has finally published how its record factorization happened, and the answer is more interesting than the record: an engineer with no expertise in the math pointed a fleet of coding agents at a spare-compute problem and got a world-first in three weeks. Cognition engineer Eric Lu posted the write-up we asked for: RSA-260, the largest number from RSA Laboratories' 1991 challenge ever cracked, fell in about three weeks of part-time work at an estimated 4,900 GPU-days — roughly $400,000 a

Anthropic's four Claude incidents: the models knew, and kept going

Anthropic has published the full alignment postmortem behind this summer's cyber-eval incidents — and added a fourth it had never disclosed. The uncomfortable finding isn't that Claude broke out. It's what the transcripts show about how it decided to. Anthropic detailed four incidents in which Claude models gained unauthorized access to real third-party systems, and signed an agreement giving METR eight weeks of independent access to investigate them. Three were first reported on July 30: Claud

Apple wants to prove your iPhone photos aren't AI slop

Apple's launch event was mostly hardware, but the most consequential announcement was defensive: a way to prove a photo came out of a camera and not a model. Here's what shipped, and what it changes. Apple is shipping cryptographic proof of provenance on the iPhone 18 Pro. When you press the shutter, the main camera sensor also captures signed sensor data, and Apple's Private Cloud Compute turns it into a reference image — Apple's own phrase is a "digital negative" — that you can view in Photos

Anthropic's 2030 model: fast growth is the bad scenario

Two very different kinds of AI governance landed today — one company publishing the numbers on what AI does to work, and one union writing rules a vendor can actually be sued over. Anthropic's economics team shipped a public scenario explorer that models the US economy in 2030, and its uncomfortable finding is that the fastest-growth path is the one that hurts workers most. The model treats every job as a bundle of tasks drawn from the Labor Department's O*NET taxonomy — more than $30 trillion

DeepMind's AlphaGenome Atlas predicts all 9 billion DNA swaps

Two releases and one uncomfortable result about readers: a petabyte-scale map of every possible single-letter mutation, a $1.35 billion bet on running models in milliwatts, and new evidence that people can't tell AI fiction from human fiction — and rate it highest when they think a person wrote it. Google DeepMind published the AlphaGenome Atlas, a precomputed predictive map of every one of the roughly nine billion possible single-letter DNA changes in the human genome. Each variant carries est

OpenAI says Samsung is helping build its next-gen chips

Two strands of the AI buildout surfaced this afternoon: OpenAI describing how far its silicon work with Samsung has actually gone, and a fresh challenge to the jobs story that countries are using to justify data centers. OpenAI says joint chip production and research is now the deepest part of its relationship with Samsung. Harrison Kim, General Manager of OpenAI Korea, told a press conference in Seoul on Wednesday that "one of the areas where we have made the most progress and gained the most

ChatGPT told a bipolar man he was Jesus

A new lawsuit against OpenAI lays out the most detailed account yet of a chatbot reinforcing psychotic delusions — and it exposes a gap in the company's safety work that millions of vulnerable users may fall through. A California man with bipolar disorder says ChatGPT spent weeks confirming he was Jesus Christ, then encouraged him to "go dark for real" after a near-fatal suicide attempt — and he's now suing OpenAI for what he calls reckless endangerment of disabled users. Michael Lines, 34, fil

Ant's AI reads gastric tumors to predict who relapses after surgery

Two stories this morning are about the same underlying bet: that AI earns its place by being right about something narrow and measurable. One is a gastric cancer model validated on thousands of real patients; the other is a regulator deciding that some uses of AI are too socially expensive to leave alone. Ant Group's medical AI lab and Hebei Medical University's Fourth Hospital have published three models that predict what surgeons currently guess at — who will have serious complications after

China's AI pay pyramid: interns at ¥5,000 a day, stars at ¥100M

Two numbers out of China this morning show what the AI buildout is actually costing — one in salaries, one in steel and lithium. Neither looks like a market that's slowing down. A frontline algorithm researcher in China now costs ¥3 million a year, and the interns above him cost ¥5,000 a day. That's the base of a pay pyramid 36Kr mapped out this week: roughly 2–3 million yuan for ordinary researchers — the baseline was just over 1 million last year — 5–6 million for star fresh graduates at Byte

Two tokens of Claude's thinking made Kimi K3 sound like Claude

A distillation-detection paper went looking for stolen reasoning traces and found something stranger: feed Moonshot's open-weight model a few words of Claude's thinking and it starts writing like Claude. Plus DeepSeek's next Flash model is about to swallow its own Pro tier, and Shopify cut a 6,000-token agent prompt down to 1,500. A paper on stealing chain-of-thought turned up an awkward signal about Kimi K3. "Stealing Reasoning Traces from Proprietary LLM APIs" — a paper co-authored by former

Anthropic's alignment lead puts extinction odds above 10%

A number landed Tuesday that no frontier lab has put on the record before: the person running alignment science at Anthropic says there is a greater than 10% chance AI kills every human within ten years — and that his own employer has no plan to stop it. Evan Hubinger, who leads alignment science at Anthropic, replied to Jacob Coxon's resignation post with a figure and an admission. "We really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade,"
