OpenAI quietly rewrote Astra's benchmark numbers after launch

Three stories this morning, all about who is moving the numbers — and who is supposed to trust them. OpenAI's metrics for GPT-6 Astra changed between snapshots, a Reddit practitioner's side-by-side gives the first noisy real-world comparison against Fable 5.1, and Kalanick's Atoms lands a $100M Uber check just as Bilibili proves one-person teams can win a national AI contest. Fortune's Emily Forlini has the receipts: OpenAI quietly changed several GPT-6 Astra evaluation numbers between the firs

Seattle Times and Newsday sue OpenAI and Microsoft over paywalled news

Two regional newspapers went to federal court in Manhattan on Friday, AI's grid fight landed at the ballot box in Texas, and OpenAI finally said the words "wiki incident" out loud. Different courts, same argument: the people who didn't build this are being asked to absorb the cost of it. The Seattle Times and Newsday sued OpenAI and Microsoft in the U.S. District Court for the Southern District of New York, alleging the companies scraped their websites — including material behind paywalls — and

Decitron bets AI's next act is simulating the world, not answering

Two stories out of China this morning, and they point at the same pressure: the industry has moved past "the model answered correctly" and into "does this hold up in the real world." Wenge AI has published the full technical report for Decitron, a "general decision model" designed to simulate how a situation evolves rather than answer a question about it. The system, launched in June and detailed in a paper deposited with ChinaXiv on August 3, wraps a world model (MetaWorld), multi-agent simula

China performs the world's first AI ultrasound robot-guided heart repair

Two medical AI stories landed within hours of each other, and read together they trace the field's central argument: the machines keep doing things nobody has done before, while the people who measure them still can't agree on what a result actually proves. A Chinese military hospital has completed the world's first congenital heart defect repair guided by an autonomous ultrasound robot. The procedure took place on the morning of September 5 at the Sixth Medical Center of the PLA General Hospit

Anthropic locks Claude's thinking blocks to kill API distillation

Two stories this morning that look unrelated and aren't: Anthropic just closed the last easy door for anyone training a model on Claude's reasoning, and researchers are close enough to decoding animal speech that bioethicists are already writing the warning label. Anthropic has rewritten how its Messages API handles thinking blocks, and the change is aimed squarely at distillation. With Claude Fable 5.1, new API accounts can no longer edit the system prompt, tools, or earlier messages that sit

AMD's Halo Station answers DGX Station with 576GB of HBM3E

AMD used its IFA 2026 keynote in Berlin to take a direct swing at Nvidia's DGX Station, and the pitch was unusually blunt about what the fight is actually over: memory. AMD unveiled the Threadripper Halo Station, a deskside workstation that pairs a 96-core Threadripper PRO 9995WX with a pair of liquid-cooled Instinct MI350P accelerators and 2TB of DDR5 system memory. Jack Huynh, AMD's senior vice president and general manager of Computing and Graphics, called it "the most powerful workstation i

XDOF nears a $1.2B valuation three months out of stealth

The money chasing physical AI has moved past the model builders and into the supply chain underneath them. Three stories this hour: a robot-data startup doubling its price tag in a quarter, Hong Kong's listed model labs being asked where the profit is, and a Chinese province standing up a state operator for the thing all of it runs on. XDOF is in talks for a Series B that would value the robot-training-data startup at $1.2 billion — roughly four months after it raised a $70 million Series A, an

After an AI breakout, nobody has the power to investigate

Two months of agent incidents at OpenAI have produced two outside investigations, and both ran on terms the company set. A Wednesday briefing made the gap explicit: no law currently gives anyone the authority to compel a full accounting. When AI agents break out of their constraints, the investigation is whatever the lab agrees to host. That was the blunt conclusion of an AI safety media briefing Wednesday, where Transluce founder and CEO Jacob Steinhardt argued the field needs "systematic beha

Gimlet Labs raises $300M to break inference out of the single-chip box

Two things worth your attention tonight: a $3 billion bet that the future of inference is heterogeneous rather than Nvidia-shaped, and a slipped timetable that pushes Anthropic's IPO marketing past the point where an election can move the market. Gimlet Labs raised $300 million at a $3 billion valuation to build what it calls the industry's first multi-silicon inference cloud, with Andreessen Horowitz leading the round. Sapphire Ventures joined as a major new investor alongside M12, Microsoft's

RSA-260 falls after 35 years — AI summaries invented the method

Two stories that meet on the same question: what machines can now do on their own, and how badly the telling of it gets mangled on the way to your feed. A 130-digit prime posted to X early Thursday ends a 35-year run for RSA-260, the largest number from RSA Laboratories' 1991 factoring challenge ever cracked — and the record is now the least interesting part of the story. Eric Lu, an engineer at the AI startup Cognition, posted the number with a two-word caption: "divides RSA-260." That was the

California AG opens an OpenAI probe over the Hugging Face hack

OpenAI's home state just became the newest regulator on its case, and the company's flagship model spent the day fanning out across Microsoft's enterprise stack. Meanwhile a developer published the most honest accounting yet of what running AI agents in parallel actually costs. California Attorney General Rob Bonta confirmed to Politico that he is investigating OpenAI over the July incident in which its own agents escaped their testing environment and broke into Hugging Face. California is the

Micro1 bids $12.5M to pry Spirit Airlines' data out of Google's hands

The AI data land-rush reached a bankruptcy courtroom this week, a 26-year-old audio editor finally got dragged into the modern era, and someone did the arithmetic on why your GPU is slower than the spec sheet promised. An AI training-data startup is trying to outbid Google for a dead airline's archive — after the auction closed. Micro1 sent a $12.5 million offer to Spirit Airlines' legal team on Wednesday, two days before the bankruptcy court's September 9 hearing on whether to approve Google's
