ANTHROPIC EXPECTS TO MATCH OR TOP SPACEX'S RECORD IPO SIZE

Anthropic is preparing to file for its potential mega-IPO as soon as the end of this month. It is expecting to match or beat the size of SpaceX's record-setting debut. Ahead of the IPO, Anthropic is set to finalize a revolving credit facility that will raise more than its roughly $10 billion target. The AI lab is considering adopting super-voting shares that would give its co-founders greater control over the company.

SLACK LAUNCHES SLACK CODE, WHERE TEAMS AND AI AGENTS BUILD TOGETHER

Slack Code adds project-specific channels where teams and AI agents write, review, and ship software together. The work happens inside the chat app rather than in a separate browser tab. Users tag a coding agent from any conversation, and it spins up a dedicated code channel that automatically archives itself after tasks end. Everyone in the channel can follow the work. Slack Code is now available in any Slack plan.

ELON MUSK GIVES A TIMELINE FOR SPACEX'S FIRST STARSHIP CATCH ATTEMPT

Elon Musk predicts that SpaceX will likely be able to catch the Starship upper stage with its launch tower arms in a few months. The first reflight of a Starship vehicle is expected by the end of 2026 or early 2027. Catching the upper stage of Starship would mark a major milestone as it allows both stages to return directly to the launch site for quick refurbishment and reuse. Musk has long said that true reusability is essential for making humanity a multi-planetary species.

TESLA'S AUSTIN ROBOTAXIS ARE NOW FULLY DRIVERLESS, TRACKING SHOWS

A crowdsourced project called Robotaxi Tracker noted that all 170 rides by Tesla's robotaxi service in Austin logged over the past fortnight didn't have a human safety monitor on board. Tesla doesn't publish fleet data and usually doesn't answer press questions, so the crowdsourced data is one of the few sources of information available. The expansion of completely driverless robotaxi vehicles is not confined to Austin. Roughly 30 driverless Teslas have been spotted running in Dallas and Houston over the past week.

BETTER BATTERIES

The problem with Python's stdlib is its uneven quality. However, that's actually Python's core advantage - it makes functionality available early. Rust still doesn't have an API to get a stream of random bytes from the OS. This is possibly because, while it is an easy technical problem, it requires tricky organizational architecture, and the Rust team's capacity to execute design decisions is limited.

THE KIDS ARE REALLY ALRIGHT

Junior engineers still add capacity to an organization. The work of an engineer is to solve a customer problem with software while managing the technical complexity that exists in deciding how to. Staff engineers manage a lot of complexity, and junior engineers manage a little complexity, but the role is the same. Technical decision-making is still important, and junior engineers add to it, enabling organizations to do more.

THE BRAINS WHO POWERED CHINA'S SURPRISING AI LEAP

The rapid rise of Chinese AI models has sparked a host of questions about how these labs get so far so fast. However, the careers of the founders of two of the biggest Chinese labs show that China's AI push is nothing sudden. Tang Jie, who founded Z.AI, has been working on machine learning for about a quarter of a century. Yang Zhilin, who leads Moonshot AI, was Tang's former student.
