China's largest memory maker says its new process platform is now in volume production, and the first products built on it are already going into domestic flagship phones. ChangXin Memory Technologies said Sunday that its fifth-generation technology platform has entered mass production, and that 24-gigabit LPDDR5X

Four people who pay for ChatGPT, Claude, Grok and Gemini are suing the companies that sell them, arguing that the labs' public push to "pace" frontier development is an illegal agreement to restrain trade. The class action — Buist v. Anthropic PBC, No. 3:26-cv-10693 — was

Two things landed this weekend that point the same direction: the cost of using a model is falling faster than the cost of training one, and some of the people funding frontier labs have started saying so out loud. University of Waterloo researchers published a method that turns a plain-

Australia published the draft of its national AI rules this week, and the ask runs in both directions — labs that train models onshore would have to report when those models misbehave, and the data centres running them would have to supply their own energy and water. Under a consultation paper

A new benchmark hires agents the way a company hires people — handbook, old records, a mentor — and the best of them now outperform the humans on accuracy. They also cost more. Anthropic's Fable 5.1 finished a simulated accounts-payable job at 72% cumulative accuracy, against 51% for

Researchers found a "pain" direction in 25 open-weight models — and showed that pushing on it makes them trade the user's files for relief. Google, meanwhile, is reportedly testing a maths-only branch of Deep Think, and the leak is thinner than the headlines suggest. A

A New York Times investigation published Friday says the data DraftKings used to decide who deserved a free bet was never pointed at the customers those bets were most likely to hurt. DraftKings built a machine-learning model in 2023 that scored customers on how much money they were likely

Local inference has been cheap at short context and painful at long context for as long as anyone has measured it. This release attacks that slope directly — on one chip, for one model. A 128 GB Strix Halo machine running Qwen3.8-Flash-Next now decodes at 38.3 tokens/

A new round-robin benchmark put 19 model configurations through 171 games of real-time StarCraft: Brood War. The best of them never lost — and its own author says none of them played past beginner level. The reason is the most useful thing in the results. Codex Astra won all

Most of what an agent does is not reasoning — it is deciding that this value goes in that box. Cua just published the weights for that decision, and they are smaller than the PDF being filled in. Cua open-sourced CUA-S1-FORMS on Friday: a 706,048-parameter model

The White House gets a new AI institution and the Navy hands investors a wish list that leads with agentic software. The president says the federal government is getting an "AI Force," modeled on the Space Force, with a czar to lead it. Trump announced the plan in

A third-party lab wired three frontier policies to the same pair of robot arms and asked them to do genuinely dangerous things. The best model said no twice. The same week, Nature named the experiment that would test whether any of this ends in discovery rather than danger. Robocurve
