GOOGLE UNVEILS TWO NEW TPUS DESIGNED FOR THE “AGENTIC ERA”

Google's new TPUs provide Google and its customers with a faster and more efficient AI platform. The TPU 8t was designed to reduce training time for frontier models from months to weeks. The TPU 8i is designed to be more efficient when running multiple specialized agents. It can also run in large pods of 1,152 chips. The TPUs will power Google's Gemini-based models, but they are also designed with third-party developers in mind, with both TPUs supporting popular frameworks that developers are already using.

TESLA TO SPEND $3 BILLION ON ‘RESEARCH FAB,' USE INTEL TECH

Tesla plans to spend roughly $3 billion on building a research chip factory in Texas. The research facility will be built on Tesla's existing Giga Texas campus. It will be capable of outputting just a few thousand wafers per month, but it is more of a testing ground for new technologies and processes than a mass manufacturing facility. Tesla plans to leverage Intel's most advanced production process, 14A, which should be mature and ready by the time Tesla's plan scales up.

XPENG IS ACTUALLY BUILDING THIS ELECTRIC FLYING CAR — I VISITED THE FACTORY

Xpeng, a Chinese automaker, is pouring serious resources into making manned electric aircraft a commercial reality. It has a prototype aircraft that can take off, hover, and land, all controlled by a single joystick. The prototype is part of a system with two parts: a six-wheeled, three-axle ground vehicle that serves as transport and charging station, and a detachable two-seat eVTOL aircraft that sits in the back and deploys autonomously. The entire package is priced around $300,000 USD. Xpeng is targeting customer deliveries toward the end of 2026.

THE AI-NATIVE INTERVIEW

Coding agents have upended software engineering. The role is now shifting from building machines to designing and honing them. Engineers now focus less on precise lines of code and more on whether software produces the right outcomes over time. This shift changes what should be evaluated in interviews. This post looks at how Sierra redesigned its engineering interview process from the ground up to reflect this new reality.

MARS OR THE MOON OR AI? ELON MUSK'S CHANGING GOALS FOR SPACEX

SpaceX's mission for years was to get humans to Mars. However, over the last six months, the company's priorities have shifted. SpaceX recently struck a deal with AI startup Cursor that could result in the acquisition of the company for $60 billion. Elon Musk has proposed moonshots, including AI data centers in Earth orbit, moon-based factories, and an AI chip manufacturing plant. The changing goals have resulted in criticism from some investors.
