Nevada just handed Elon Musk's robotaxi ambitions a reality check: Tesla got its permit — but regulators capped the fleet at 10 cars, not the 5,000 the company asked for, and loaded the order with restrictions that make Las Vegas a test run rather than a launchpad. The

Every leaderboard number carries a quiet question: did the model learn the material, or memorize the exam? A preprint posted to arXiv this week gives auditors a sharper way to tell the difference — one built for the exact regime where today's detectors go blind. A new protocol proposes

The case for letting AI write GPU kernels just met its sharpest audit yet: a new verifier argues that the field's standard correctness test is so loose it waves through broken code most of the time. A team of researchers built a contract-grade verifier for LLM-generated

The "AI does AI research" narrative took a hit from an independent evaluation today, Google quietly made visible AI watermarks optional, and the company pushed encrypted inference a step closer to production. A busy morning for the frontier — and for the people trying to verify its claims. A

Alibaba's Qwen delivered the open-source model the community kept asking for, and Meta's most expensive hire walked out the door — a Friday that splits cleanly into two stories. Alibaba's Qwen open-sourced Qwen3.8-27B on Friday under the permissive Apache 2.0

SpaceX just closed the largest startup acquisition on record, folding AI coding tool Cursor into a new SpaceXAI division with the brand set to fade into Grok — and co-packaged optics officially hit the mass-production phase of the AI buildout. SpaceX finalized its $60 billion all-stock acquisition of

Two enterprise moves set the tone today: IBM is putting tens of thousands of consultants behind OpenAI's models, and a startup founded by a former OpenAI researcher just banked several hundred million yuan to chase physical AI. IBM announced Thursday it is building a dedicated OpenAI practice inside

The AI buildout's hardest constraint is showing up in opinion polls, not supply chains: a new national survey puts local opposition to data centers at 61% and rising, while one of the chip industry's founding figures warns the market's financing structure is running ahead
The Stack
DeepSeek is moving up the stack from models to the software developers actually use, and Uber is scaling robotaxis across Europe. Two open-source and mobility moves to start your Friday. DeepSeek released DeepSeek Harness (dsh), an open-source agent harness under the MIT license in developer preview, built on

Baidu went all-in on AI office work at its AI Day event on Thursday, giving its most popular assistant a Chinese name, standalone apps, and an enterprise edition. Baidu renamed its Wenku-Netdisk assistant GenFlow to 库库AI (Kuku AI) and claimed more than 25 million monthly active users in
