Two stories that put the AI boom's hard infrastructure on the front page: a Chinese memory chipmaker just printed its first massive profit, and an AI-powered brand-protection tool has booted a popular open-source game off Google Play with a takedown that doesn't even

The morning catch-up: a community deep-dive finds that Qwen's new "Engram" memory layer is mostly cold cache, China publishes medical-imaging AI ethics rules, an open-source long-form TTS lands, and a regional government tries to seed 100 industrial AI scenes. A community

A major music marketplace just drew a hard line on AI-made tracks — and the new policy comes with a built-in detector, a user survey showing DJs overwhelmingly prefer human-made music, and a notice system that tells rights holders when a track is rejected. Plus: two alleged members

South Korea has picked SK Telecom, KT, and Kakao to run "AI for All," a public-utility program that will give every Korean citizen free, unlimited access to frontier AI chatbots and agents by the end of 2026 — and the government is putting real money behind it. South

AI's appetite for memory is colliding with a hard physical limit, and the chipmakers are running out of room to hide it. Two stories from the last 24 hours — one from a conference stage, one from a balance sheet — show the same problem from different sides. Micron used

Two Chinese AI stories landed today that point in opposite directions on what "working" looks like at scale: a Hong Kong-listed industry-agent company posted real growth on a Palantir-style model, and one of the country's largest healthcare AI products inked a deal to
The Frontier
Two robotics papers out of China this week are quietly rewriting what "embodied AI" actually has to know. A VLA model from Da Xiao and HKU learns to read continuous time, and a single-video pipeline from Niuwa, SJTU, and Shandong lets a robot push through a door
The Guardrails
The 2026 story about who a frontier model is allowed to help just got a vivid field test, and the field test was run by a paying customer on a $114 tablet. Eric Pardee, a 20-year InfoSec engineer, wanted to own hardware he had already bought. Five months and

The always-on agent race got a real code drop today. OpenAI is wiring a new "Persistent" setting into Codex's reasoning-effort menu — the closest a frontier lab has come to shipping a product around the idea of an agent that doesn't politely end
The Stack
Reinforcement learning from human feedback (RLHF) is the training technique that teaches an AI model what people actually prefer — by using human ratings, not just text, as the signal for what counts as a good answer. It is the reason a chatbot says "I'm not sure, let

China's open-weight race just got its heaviest new contender, and Tencent is pitching it as a productivity workhorse rather than a benchmark-chaser. Tencent is open-sourcing Hy4 preview, a 770 billion-parameter Mixture-of-Experts model with a 1 million-token context window. The architecture activates

The man who built OpenAI's o1 and o3 reasoning models now runs a lab whose stated goal is to make researchers like him obsolete — and he has put a number on how fast it will happen. Jerry Tworek, the former OpenAI research vice president who led the o-
