FERRARI LAUNCHES $640,000, JONY IVE-DESIGNED, GLASS-CLAD ELECTRIC SPEEDSTER

The Ferrari Luce, designed in partnership with Jony Ive, is an electric vehicle that will test the appetite of the superrich for EVs. The first Ferrari with five seats, the Luce will be among the most expensive Ferraris that aren't part of a limited production run at a starting price of roughly $640,000. It accelerates from 0 to 60 miles an hour in less than 2.5 seconds with a top speed that exceeds 190 mph. The vehicle has a range of roughly 330 miles despite an unusually large battery.

HUAWEI SAYS IT HAS WORKAROUND TO MATCH LEADING CHIPS

Huawei expects to be able to make chips on par with leading products manufactured by Intel and other top global companies by 2031. It has developed a technique that can create chips that match the transistor density of those manufactured with a 1.4-nanometer process. The US has restricted China's access to advanced semiconductor technologies since 2022. Huawei's technology could remove this obstacle for China in its tech rivalry with the US.

JAPAN'S NEW HYPERSONIC ENGINE COULD MAKE 2-HOUR FLIGHTS TO THE US A REALITY

A team of engineers from Japan's Aerospace Exploration Agency (JAXA) and several Japanese universities has completed a successful ground combustion trial of a ramjet engine designed for a Mach-5 hypersonic aircraft. The test simulated a flight at five times the speed of sound. It was focused on validating the aircraft's heat-shielding, control surfaces, and engine performance under extreme conditions. The project's goal is commercial hypersonic passenger service by the 2040s.

A TERMINAL IS ALL YOU NEED FOR WEB AGENTS

Microsoft Webwright is a simple SWE-style browser agent framework that achieves state-of-the-art results on long-horizon web tasks. It gives agents a terminal that allows them to launch multiple browser sessions to inspect pages and complete web tasks. Webwright captures and inspects screenshots only when needed, and it enforces each web task to be completed end-to-end within a re-runnable Python script. It uses a small harness that adds just enough structure around completion, context, and reuse to avoid creating new failure modes.

ON-POLICY DISTILLATION

On-policy distillation trains a student model on trajectories sampled from its own policy while a teacher provides dense token-level supervision through KL-based regularization, closing the train-inference distribution mismatch that off-policy methods suffer. The canonical formulation unifies forward-KL, reverse-KL, and JSD losses with reverse-KL emerging as the default for mode-seeking smaller students, and a one-line code swap of the regularizer model on top of an RL stack like Tinker implements the technique.

HOW DESIGNERS CAN HANDLE FINANCE STUFF WITHOUT LOSING CREATIVE FLOW

Designers often struggle with finance tasks because they require a completely different mindset than creative work, disrupting their flow. The solution is to batch administrative tasks into dedicated "office hours" and automate repetitive processes like payment tracking and invoicing. As design businesses grow and add team members, having professional financial systems becomes crucial for maintaining trust and allowing everyone to focus on creative work.

WHEN DESIGNERS START BUILDING

Automattic ran a workshop where twenty designers learned to work directly in production codebases instead of just handing off designs to engineering teams. The goal was to close the gap between design and final product by having designers build with real components and APIs rather than just creating mockups in Figma. By the end, several designers had opened their first pull requests and were making design decisions directly in the codebase, representing a shift toward designers working closer to the actual product.

THE DESIGN SYSTEM ADVANTAGE IS MEMORY

The real advantage in AI-powered design systems is not the number of tools or the sophistication of the model, but whether agents can access and reason over a company's accumulated decision-making memory — including design critiques, Slack discussions, ADRs, deprecated patterns, and research history. As AI agents take on longer and more complex tasks, poor context retrieval becomes increasingly expensive in both compute costs and human oversight, leading to repeated corrections and lost trust. The proposed solution is to structure organizational knowledge into searchable indexes or graph-based systems that connect components, decisions, owners, and outcomes, allowing agents to retrieve the right context before acting instead of repeatedly rediscovering it.
