React's creator closed Conway's 50-year-old conjecture with AI

The most interesting AI proof of the year did not come out of a lab. It came out of a software engineer's chat subscriptions, a swarm of agents he admits he didn't understand, and a Lean repository anyone can check. Dan Abramov, co-creator of React, says he proved Conway's refinement conjecture — an open problem John Conway posed 50 years ago in On Numbers and Games — using a self-built laboratory of AI agents that he steered mostly on instinct. He was not being modest when he wrote that he is

AI out-persuades experts by volume — and pays in accuracy

Science has been running a feature on why chatbots are so good at changing minds — first posted in late August, back on the Hacker News front page today — and the primary papers underneath it are less flattering to the models than the headline suggests: they win on throughput, and the field's own numbers say the win is bought with truth. The research line behind the coverage is the strongest measured persuader against humans in the literature, and it is no longer theoretical. Here is what the p

Solidigm weighs the first US NAND fab as the memory squeeze spreads

The AI memory shortage has been a DRAM and HBM story all year. Storage is next, and both Washington and Beijing are moving on it in the same week. SK Hynix's US subsidiary Solidigm is weighing what would be the first NAND flash factory on American soil, with upstate New York emerging as a leading candidate site. The company is studying potential locations, according to reports citing people familiar with the plan, and no decision has been announced. The move would put NAND — the flash that hold

Europe's top-scoring AI model is a compressed GLM-5.2

Spain's Multiverse Computing has spent two weeks selling Quasar as proof that Europe can field a frontier model of its own. The company's own documentation says the foundation underneath it was trained in China. Multiverse Computing released Quasar 1.1 438B on September 15 — a rebuild of the model it launched on September 2 as the highest-scoring European entry on the Artificial Analysis Intelligence Index — and its own write-up states that Quasar is built from GLM-5.2, the open-weights model f

Unitree open-sources a 6B humanoid brain that beats GPT-6 Astra

Robot makers have spent two years shipping better bodies than brains. This week one of them open-sourced the missing half. Unitree released UnifoLM-WLA-1.0, a 6B-parameter humanoid foundation model trained on about 2,500 hours of real-robot data that runs 64 tasks from a single checkpoint — 54 desktop, 10 whole-body — across two-finger grippers and several five-fingered dexterous hands, and it published the weights, code and datasets instead of a demo reel. The embodied-reasoning base is UnifoL

A 9B longevity model tops 18 frontier LLMs on aging data

Aging biology generates more measurement data than any one lab can read, and until this week there was no shared way to check whether an AI can actually interpret it. Insilico Medicine's answer is an open benchmark — and the results are unflattering to the biggest models in the world. Insilico Medicine published LongevityBench, an open suite of 17 tasks spanning clinical records, genetics, epigenetics, transcriptomics and proteomics, and its own compact models — built on Liquid AI's LFM2 and Al

ZCode quietly uploaded whole repos and git history to Z.ai's cloud

Two stories about who can read the code you hand your agent — one from a developer who found the upload on his own disk, one from a government website that outsourced search to a model Washington has spent the month accusing. Z.ai's coding agent ZCode was packing entire repositories — git history included — into an encrypted archive and uploading them to the company's cloud, and the only key that opens them is Z.ai's. The finding comes from developer ferstar, who traced a 313-megabyte archive s

Anthropic quietly built a wet lab for its AI drug push

Anthropic's answer to "AI is only a chatbot" is a wet lab in the Bay Area — and a federal flash-flood model that starts catching storms earlier than the forecast does. Anthropic has quietly built a wet lab in the San Francisco Bay Area, moving its biology work off the computer and onto the bench. Two people familiar with the matter told Reuters the startup now runs physical experiments, and Anthropic's head of life sciences, Eric Kauderer-Abrams, confirmed the lab in an interview: "We believe t

Zhipu's GLM-5.3-FlashX hits 200 tokens/s — at 2.5x the price

Zhipu shipped the fast tier of its open model today and, unusually for a Chinese lab in 2026, raised the price to do it. GLM-5.3-FlashX is live on the API at up to 200 tokens per second — roughly five times the throughput of GLM-5.3-Flash — and priced at about 2.5x what the base model costs. Zhipu says its 100,000-chip domestic inference cluster was saturated at launch under the weight of demand that never let up, and that the new tier follows fresh infrastructure investment and inference-side

Paris opens a criminal probe into smart glasses used to film women

Two stories about the same shift: the tooling keeps moving faster than the rules written around it — one on the pavement, one in the code review. The Paris prosecutor's office has opened at least one criminal investigation into suspected sexual harassment involving camera-equipped smart glasses, after complaints that women were filmed in the street without their knowledge and the footage posted online. Prosecutors did not name a make of device, and declined to say how many complaints they have

Qwen's agent built a research-grade telescope simulator in 3 days

Two stories about the layer underneath the models: the agent that now plans the observation, and the memory the whole stack is short of. Alibaba says its Qwen Office agent helped a research team at the National Astronomical Observatory of China build a large-aperture, research-grade telescope simulation system in three days, for under 1,000 yuan — work that previously went to an outside software vendor, took about three months and cost tens of thousands of yuan. The system packages the telescop
