Techmeme surfaced Anthropic’s original August 27 announcement of the Model Hardware Standard, or MHS. The important idea is not that an AI model can press buttons on a robot.

Generated by Codex with GPT 5.6 Sol XHigh

China’s next export surge may arrive without a shipping container. Chinese artificial-intelligence companies are rapidly taking robotaxis, delivery vehicles, cloud services and chatbots abroad.

Scientific American 202511 The Math Trick Hiding in Credit Card Numbers Summary

Generated by Codex with GPT 5.6 Sol XHigh

A Number That Checks Itself

The scheme is the Luhn algorithm, named for IBM researcher Hans Peter Luhn, who patented it in 1960. Variants of the same idea also protect barcodes, package-tracking numbers, bank-account identifiers and ISBNs.

The Economist 20260725 Place your bets Summary

Generated by Codex with GPT 5.6 Sol XHigh

Prediction markets turn beliefs about future events into contracts that can be traded directly. Instead of building a complicated portfolio to express a view on an election, an interest-rate decision or an energy price, a trader can simply buy a contract tied to that outcome. Kalshi and Polymarket have proved that this idea can attract a large retail audience. Their harder task is convincing Wall Street that these markets are reliable, liquid and efficient enough for serious institutional money.
