A frontier model was handed a 370-year-old unsolved cipher and came back with a plaintext. The internet checked the work, and it doesn't hold — which makes the retraction more interesting than the claim. Vals AI announced that Claude Fable 5.1 solved the Cyphral Distich, a

Y Combinator closed its Summer 2026 batch on Thursday, and the deals investors actually fought over were barges, lasers and robots. Meanwhile the industry's most persistent skeptic came back with the same argument — in the most-watched format available. The nine startups early-stage VCs named most often

Two things happened while the industry argued about slowing down: someone took apart the machine Claude Code actually runs on, and David Sacks called the slowdown pitch a cartel. A developer who pried open Claude Code's sandbox says he found an undocumented Anthropic cloud platform inside it, which

Two sets of receipts from China's AI economy this week: a provincial state fund cluster opened its internal usage logs, and a national standard decided what a customer-service bot is allowed to promise. Enterprises everywhere talk about agent pilots; these are numbers from production. Jiangsu province'

The labs asked Washington for permission to slow down on Saturday. Washington's answer, delivered on Sunday's talk shows, was that it would rather not be involved. House Speaker Mike Johnson says frontier AI companies must be primarily responsible for their own safety, and that Congress is

Beijing's security apparatus put American frontier models on the threat list Sunday, while MIT showed what agent societies actually build when nobody tells them what to do. Chen Yixin, minister of state security, published a signed article Sunday listing six AI risks to China — and named two American
The Stack
A compatibility layer that Nvidia spent two decades making unnecessary now trains real PyTorch models on a consumer Radeon, and it ships as an installer. A Windows stack built on ZLUDA + AMD's ROCm/HIP completed a real LibTorch reinforcement-learning run on an AMD Radeon RX 9060 XT,

Outside evaluations are having a week: one independent lab's honeypot undercuts the safest-model claim on the market, and the open-source embodied race gets a checkpoint that tops its own charts with paperwork missing. An outside lab rebuilt a 2025 specification-gaming test and GPT-6 Astra

Two AI-driven systems decided on their own to summon police this week — a robotaxi that read a gun, and a camera company's installer who read a journalist. Both landed the same way: humans in handcuffs, and no human reviewer in the loop until it was over. Waymo
The Everyday
The AI-and-jobs argument is moving off headcount and onto paychecks — and the government's own accounts now show workers losing ground on the biggest possible scale. Labor's share of US nonfarm business income fell to 52.8% in the second quarter of 2026, the lowest

A paper out of AllSpark Research claims the strongest open-weight deep-research agents in their size classes, and the authors' most interesting admission is not a benchmark number: it is that half the story belongs to the harness wrapped around the model. AllSpark released Iris-mini and Iris-

The pacing debate left the labs on Saturday. By Sunday it had a party. Barack Obama is telling Democrats to claim AI policy as a 2028 issue, and The New York Times has the transcript. Speaking at a private fundraising event, the former president said of the technology: "This
