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

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

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

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

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

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

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

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

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

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

A nameless model dropped onto OpenRouter and immediately out-scored the biggest names in coding — and the detective work on its identity is as interesting as the model itself. Ox Alpha, an anonymous "stealth model" that appeared on OpenRouter on August 20, is posting coding-test scores above

Your agent's model is fine. Its browser disguise is what's blowing your scraping runs — and a maintainer of an open-source automation library has the test numbers to show it. The most useful agent engineering post of the day didn't come from a lab
