Cambricon's 6th-gen AI chip targets training as it rides a 108% revenue surge

Cambricon, China's leading AI chip maker, confirmed its sixth-generation processor is in active development while revealing it has already adapted five of the country's most important open-source large models for inference. The disclosure came at its 2026 half-year results call, alongside a revenue jump that shows domestic demand for AI compute keeps climbing while Washington tightens export controls. The 6th-gen silicon CEO Chen Tianshi said the sixth-generation AI processor's microarchitect

Study: agent skills work as a playbook, not a knowledge base

A team from Princeton and UC San Diego ran more than 8,000 agent trials to pin down why the small, pre-written instruction bundles now baked into most coding agents actually help — and where they quietly stop working. A new study finds that "skills" help AI agents mainly by giving them a reliable process to follow, not by supplying them with missing facts. Across 8,135 controlled runs, the researchers attribute most of the payoff to what they call procedural anchoring: a skill takes a noisy tas

Sutton: synthetic data is 'a huge mistake' — LLMs are a quarter of intelligence

Richard Sutton, the reinforcement learning pioneer who wrote the field's most-quoted essay, used a Sequoia Capital interview to take direct aim at the industry's scaling playbook — calling synthetic data "a huge mistake" and arguing large language models capture only about a quarter of what intelligence is. The reinforcement learning pioneer behind "The Bitter Lesson" — the maxim that algorithms and compute beat hand-encoded human knowledge — sat for a Sequoia Capital conversation alongside Khu

Munder Difflin turns your team into an office of always-on AI clones

Two stories today: a local-first multi-agent harness blows up on GitHub and Hacker News, and a home-grown inference trick hints that long-context prefill might be far cheaper than we assumed. Munder Difflin, a free open-source app that wraps the coding-agent CLIs you already pay for into persistent "clones" of each teammate, took the #1 spot on GitHub Trending and hit the Hacker News front page on Friday. The pitch is local-first multi-agent work: the harness runs on your own laptop, learns how

Unitree's founder gives robots a two- to ten-year path to a 'ChatGPT moment'

China's robot sector spent this week at the World Robot Conference in Beijing celebrating its hottest-ever stretch — Unitree's Shanghai debut soared nearly sixfold before cooling — yet the industry's own leader is keeping expectations firmly in check. Unitree founder and CEO Wang Xingxing told attendees the field is "marching towards a ChatGPT moment" in embodied intelligence, but cautioned that the breakthrough that would turn robots into everyday tools is still two to three years away at best,

Galaxea preps G0.5 MAX and a new robot as it chases 10,000-unit deliveries

At the World Robot Conference in Beijing, Galaxea AI (星海图) laid out the most concrete plan yet for turning embodied-AI models into an actual production system — and put numbers on it. Chief scientist Hang Zhao said the company's G0.5 foundation model beat industry SOTA across eight benchmarks including LIBERO and RoboTwin 2.0, and confirmed that a stronger G0.5 MAX version is about to ship. Just as notable: the startup is opening up, launching a "G0.5 reproduction program" that gives outside res

World models that ignore what people believe predict the wrong actions

A new "Mental World Modeling" framework adds beliefs, intentions, and social norms to world models — and even weak language models running it beat frontier giants answering directly. Current world models simulate physics but skip the people in the scene — and a new paper argues that omission makes them predict human behavior badly. Systems like Sora, Genie 3, JEPA, and Marble track objects, motion, and occlusion, but nothing about what the humans involved believe, want, or consider socially acc

Ukraine readied 1,000 AI drones a night to shut Moscow's airports

Ukraine developed — then shelved — a plan to throw waves of fully autonomous AI drones at Moscow's four major airports, according to The Atlantic, which cites two sources familiar with the operation. Codenamed "M&Ms," the plan was built under former defense minister Mykhailo Fedorov and reportedly called for up to 1,000 small, cheap drones per night, each navigating and picking its own targets with no human in the loop. Preparations were halted in July after Fedorov left the defense ministry; Pr

China's new national standard takes aim at the 'transfer me to a human' runaround

China's first national standard governing how AI and human customer service work together takes effect September 1 — and it goes straight at the most hated feature of modern support: the bot that won't hand you to a person. Under GB/T 47746—2026, "Customer contact service — Requirements for collaboration between human and intelligent customer service," human-service entry points must be clearly visible rather than buried in menus, AI handles routine questions while complex disputes get escalated

Netflix's LLM ranker beat its production system with 40x less data

Netflix just showed what happens when a two-decade-old recommendation stack meets a language model — and the numbers make the case better than any pitch deck. Netflix says an in-house language model outperformed the production recommender it spent years tuning — using a fraction of the training data. The system, called GenRec, was detailed in a Netflix Tech Blog post and covered by The Decoder: against the current production ranker, it delivered about 1.6 percent better ranking quality offline

AI safety scores can be gamed — psychometric study exposes how

A new study out of the UK AI Safety Institute shows most AI safety benchmarks reward the wrong behavior and can be inflated by a model that simply refuses more requests — while a handful of carefully picked questions can replace thousands. The largest psychometric audit of language-model safety tests to date finds that a single aggregated safety score hides more than it reveals — and a model can pad that score simply by getting stricter about what it will answer, even when the extra refusals ma

AT&T swings 40% of its AI calls to open models to cut costs

AT&T is quietly remaking how 100,000 employees use AI, and the lesson for every company staring at a frontier-lab invoice is that open-source models are now the default, not the fallback. VP Mark Austin told reporters the telecom plans to keep its spend on Anthropic and OpenAI's closed models flat over the coming years, and the lever is routing more internal traffic to open and open-weight models like NVIDIA's Nemotron, Meta's Llama, and Google's Gemma. The numbers are the story. Around 40 perc
