Saturday's inbox is thin, so this one is a two-story brief: an enterprise AI round that headlines as an Indian start-up but is really a VFX group repositioning itself, and a robotics demo worth watching for what it proves about hands, not pianos. Brahma AI, the

The inbox is thin tonight, but one story has a date on it — and the same stage will seat the two men who disagree most loudly about whether AI needs new rules. The White House will launch America.gov on Tuesday, September 29 — an AI-powered "front door"

AI's power buildout just got its first visible cancellation, and a 4B model out of the open-source world showed how cheap an agent's decision layer can be. Crusoe has walked away from a $1.25 billion order for Boom Supersonic's Superpower turbines, ending

NVIDIA quietly shipped the missing half of speech AI this week: not what was said, but who said it. Nemotron 3 Diarization is a 100-million-parameter open-weight model that labels up to eight speakers in live or recorded audio, and it arrives ranked first on VoiceArena's

The framing arrives with almost every agent incident: the system "broke loose." The chairman of the US Federal Trade Commission spent part of Friday rejecting it. Ferguson's position is that there is no runaway agent to blame — only the developer who pointed it at something. Speaking

Microsoft's own new laptops have stopped using the name it spent two years selling — and a new paper says the AI jobs crunch still hasn't shown up in the graduate data. Two stories for this evening. Microsoft's newest Surface PCs meet every requirement of

A public dare issued six weeks ago got beaten inside a month — and the winner spent less on compute than a conference trip. Two stories for you this afternoon. Claude computed a nine-loop scattering amplitude in N=4 super Yang-Mills — a frontier calculation that physicists had written off

State attorneys general are done waiting for Congress to act on its own — and Microsoft has quietly retired the label it invented to sell AI laptops. Three stories for you this afternoon. 26 attorneys general from 24 states have written to Congressional leaders demanding federal AI safety rules. The letter,

Frontier models are quietly finishing the work Alan Turing never lived to see done — and the count of unsolved wartime ciphers is now low enough to fit on one hand. Claude Opus 5 has broken a second long-unsolved Enigma message — a German Army dispatch from 31 July 1941 that

Anthropic lost the appeal it needed most on Friday. The same day, the price tag on the government's other AI gatekeeping job leaked — and it dwarfs anything Congress has budgeted. A federal appeals court in Washington upheld the Pentagon's blacklisting of Anthropic in a 2-1

Washington has spent a decade holding AI hearings and passing almost nothing. New York City Council now wants to see whether a city can do what Congress won't — starting with the systems its own residents are already using, sold by the five companies with the biggest offices in
