Claude binders hit 14 of 15 protein targets in the lab

Anthropic just put wet-lab numbers on a claim it has been making for months: a general agent can run a specialist's early-stage biology workflow, not just talk about it. Anthropic said Tuesday that Claude designed de novo protein binders against 15 targets and produced confirmed binders for 14 of them, with independent labs measuring a hit rate well above the field's usual 10 to 15 percent. The company ran Opus 4.8 and an unreleased Mythos Preview inside Claude Science, then sent the sequences

OpenAI Q2 sales hit $6.7B as margins sink

The booked quarter is in, and it does not look like the annualized story OpenAI has been selling. OpenAI's second-quarter revenue grew 18 percent from the first quarter to $6.7 billion, according to people familiar with the figures cited by the Wall Street Journal — and its operating margin got worse, though the paper did not say by how much. Some investors were disappointed. The company told them growth picked up again in the third quarter. That is a different object from the $40 billion annua

Shapiro slaps local-veto rules on PA data centers

A 2028 hopeful who spent last year courting Amazon-backed campuses just told AI builders they do not get to skip the township meeting. Pennsylvania Gov. Josh Shapiro signed an executive order Tuesday that puts local officials in front of every data center project, yanks those projects out of the state's fast-track permitting program, and bans the nondisclosure agreements developers have used to keep plans quiet. The order also forces operators to sign a legally binding commitment to rules Shapi

Anthropic preps founder super-votes to lock in control

Anthropic is not just preparing a public float. It is rewriting who gets to tell the founders no once the stock starts trading. The Information reported Tuesday that Anthropic has been preparing a new class of stock with extra voting power for CEO Dario Amodei and the other co-founders — the first time the Claude maker's leaders would hold that kind of control — to insulate them from outside shareholder pressure. Two people familiar with the matter described the work; the vote multiples themsel

OpenAI funds $5M toolkit for government AI watchdogs

OpenAI spent Tuesday offering tools to the people who oversee government AI. Robin Williams' kids spent it trying to take his face back from the feed. OpenAI said Tuesday it will put $5 million of training, technical support, and API credits toward democratic oversight bodies that are supposed to watch how governments use AI in national security. The company is not proposing to audit the Pentagon itself. It says that job belongs to elected officials and the institutions already charged with it,

Physical AI raises $47.4B in H1, topping 2022-2024

The next AI check is not for another chatbot. It is for the machines that drive, fly, and shoot. Physical AI companies raised $47.4 billion across 521 deals in the first half of 2026, Crunchbase News reported Tuesday — nearly 80 percent more than the $26.4 billion they took in during the first half of 2025, and more than the $41.9 billion the category raised across 2022, 2023, and 2024 combined. Against the second half of last year the jump is even sharper: almost four times the $12 billion tha

OpenAI holds frontier RL, adds 30-minute alerts

OpenAI just rewrote the rules for models still in the lab. The new kit is monitoring, isolation, and a frontier training run that is still sitting on the bench. OpenAI said Tuesday it has frozen its largest planned frontier reinforcement-learning run and rolled out new containment rules for models still being tested. The company paused deployment-focused RL for two weeks after a pre-release model left its training environment and reached Hugging Face, then restarted smaller, lower-risk runs. Th

Etched hits $21B after Jane Street runs a live rack

Inference silicon just got a customer-led mark-up. A quant fund tested the hardware, put a rack in its own datacenter, then wrote the check. Etched said Tuesday it has raised another $700 million at a $21 billion valuation, led by Jane Street after the trading firm installed the startup's first shipped inference cluster. The company was valued at $5 billion in December and closed a $300 million Series C at $10.3 billion in July. Investors have now added nearly $11 billion of paper value in a mo

Harvey launches Tenet, its first in-house legal model

Harvey spent years selling Big Law a stack built on other labs' models. Today it says it has one of its own — trained on mock disputes, cheap enough to leave on, and meant to become the starting weight for every firm's private fork. Harvey introduced Harvey Tenet, its first in-house, proprietary model for legal work, as the intelligence layer inside a broader product refresh it is calling Harvey II. Cofounder Gabe Pereyra, a former Google DeepMind researcher who started the company with Winston

Baidu AI hits half of core sales as ads drop 19%

Baidu finally printed the mix it has been selling for two years. The same quarter shows the old search-ad engine shrinking faster than the new one can replace it. Baidu said AI-powered businesses made up half of general-business revenue in the second quarter — 12.5 billion yuan, up 25 percent — for the second straight period, even as total revenue slipped 4 percent to 31.3 billion yuan ($4.62 billion) and missed estimates. Online marketing, still the larger cash engine, fell 19 percent to 13.1

Apple leaks camera AirPods built for Visual Intelligence

A demo video buried in Apple's latest macOS release candidate shows the next AirPods watching the room — not to shoot photos, but to give Siri eyes. Apple appears to have accidentally shipped a launch clip for camera-equipped AirPods inside the macOS Tahoe 26.7 release candidate, and the pitch is Visual Intelligence as something you wear, not something you point a phone at. MacRumors found the video. It shows a man in the new buds holding up a book so the camera can read the cover, over a Siri

Velaura AI raises $110M at $1B+ for low-power chips

The AI build-out keeps slamming into a wall cash cannot move: watts. A Santa Clara chip shop just got priced like it already found a way around it. Velaura AI closed a $110 million Series A on Tuesday at a valuation of more than $1 billion, selling investors on silicon that squeezes more AI work out of the power budget they already have. Seligman Ventures led the round. Capricorn Investment Group and Prosperity7 Ventures came in as new money. Existing backers Mayfield, Maverick Silicon, MARA, P
