OpenAI is finally putting a name on the teen product it spent a year assembling. A continent away, Perplexity's India giveaway is starting to look like more than a download spike. OpenAI launched ChatGPT for Teens on Tuesday, automatically routing anyone it estimates is under 18 — or who says they are 13 to 17 — into a locked-down experience built around homework help and default safety rails.

Five European Central Bank economists just argued that history does not care whether today's AI valuations are a bubble or a fair bet — either way, a pullback is the base case. A Monday ECB Blog post concludes that a correction in current stock-market valuations is likely, even if prices fairly reflect how much AI will remake profits.

A JAMA Perspective published Monday asks regulators not to hard-code a physician veto into medical AI — just as the evidence for that future is still mostly simulated. Ezekiel Emanuel and three coauthors argue in JAMA that autonomous AI will soon outperform any doctor-plus-model team at medical reasoning, and that writing a human into the loop now would lock in worse care.

The coding-agent parade took a day off. Today's daily board is a 107k-star video factory still shipping, an AI pentester that validates its own findings, a Mac inference server built for real coding work, and a memory layer that survives switching vendors. MoneyPrinterTurbo (Python, ~107k stars) — Give it a topic or keyword and it writes the script, pulls footage, burns in subtitles and music, and hands you an HD short.

We flagged the 17 percent number this morning in Context compaction drops 83% of user rules. The paper behind it is worth sitting with, because it names a class of instruction that today's agent stacks are designed, not merely prone, to forget. When a long chat or an agent run fills the window, the product does not usually stop. It summarizes what happened, throws the original transcript away, and keeps going on the summary. Labs call that compaction.

Long chats get summarized so the model can keep going. The summary keeps the job. It throws away how you asked to be treated. Penn State researchers find that when AI systems compress a long conversation to free context, they retain only 17 percent of the session rules users actually set — things like "don't send email without my approval" or "confirm with me before you change anything." Zhiqi Wang, Yichi Zhang, Dongwon Lee, and Yuchen Yang call these session constraints: instructions that…

An AI agent is a system that uses a language model to do a job for you — not just answer a question, but pick the next step, use tools, and keep going until the work is finished. A chatbot waits for you. An agent takes the goal and acts. That is the whole difference, and it is why the word is on every product page this year. Why it matters right now Software used to automate work by following a script a human wrote in advance. Agents flip that: the model writes the next step as it goes.

Hollywood spent the winter calling ByteDance's video model a machine for wholesale infringement. On Monday it signed a truce instead. ByteDance and the Motion Picture Association signed a formal agreement on Monday to tighten copyright safeguards on Seedance and Seedream — the video and image generators sitting behind TikTok, CapCut, and Dreamina — six months after the studios' trade group sent a cease-and-desist and called Seedance an engine of "systemic infringement." The deal covers the…

The House's statute-writers now spend more time unpicking chatbot bills than they would writing the laws themselves. The House Office of Legislative Counsel is being buried under AI-generated bill drafts — many of them wrong — and the lawyers who turn policy ideas into statutes say the cleanup is slower than starting from a blank page.

Two months after Washington yanked foreign access to Anthropic's newest models, London is finally asking what that would cost. Britain's Cabinet Office has asked the ministry that oversees business, science and trade to measure the economic hit if the UK is locked out of the latest frontier AI models, the Financial Times reports, citing people familiar with the matter. The review is expected in a matter of weeks.

South Korea's central bank just put a number on the career-ladder problem everyone has been arguing about: the jobs disappearing first are the ones young people used to learn on. The Bank of Korea says 285,000 youth jobs vanished in four years — and 94 percent of them sat in industries most exposed to AI. From June 2022 to June 2026, employment among 15-to-29-year-olds fell by 285,000, according to Issue Note 2026-19 from the bank's employment research team.

A week after Anthropic started stamping every Claude answer, the first public stripper is already a star on GitHub — and its author is more honest than the hype around it. Guillaume Meyer's watermarks-remover has passed 13,000 GitHub stars and 1,400 forks since it landed on August 11, the same day Anthropic told the world Claude would mark its output. The MIT-licensed project is an agent skill plus a local Python service.
