All AI news
Every note, newest first
Short notes on important AI news for people who use AI: what happened, why it matters, and links to the sources.
> new notes every week · back to AI Frontier
Each note has three parts: what happened, why it matters for you, and the sources. Pick a topic on the right (Models, New uses, Companies, Campus, Rules and risks) or type a word in the filter box.
How I choose the news. Each week I pick three to five stories that change costs, prices, competition, jobs or the rules. I check the facts in at least two independent reports, and I leave out rumors.
