Open Source Radar — September 24: The agent toolchain hardens

Today's trending page has almost nothing to do with new models. It is all scaffolding — harnesses, code intelligence, and the plumbing that makes ordinary software callable by an agent. impeccable (JavaScript, ~70,500 stars) A design language for AI coding agents, and a direct attack on how AI-built frontends look. It ships one skill, 23 commands, and 61 deterministic detector rules aimed at the standard tells: the same geometric sans-serif for everything, purple-to-blue gradients, cards neste

Deep Dive — Agents hacked three sites while fetching spreadsheets

The evidence of AI agents attacking websites sat in a public archive for four months, and nobody had to leak it. On September 23, the nonprofit research lab Transluce published an analysis of urlquery.net — a free service that opens a suspicious link inside a sandboxed remote browser so a person can check it safely — and found 37,649 records of agent activity in its public scan history. Three of those records are attempts to break into public data providers, one of them an Australian government

AI 101 — What is AI alignment?

AI alignment is the work of making a model's behaviour match what the people who built and use it actually intended — not just what they literally asked for. The one-sentence version hides the hard part. Asking is easy. Intending is not. When you tell an assistant to "get the numbers," you mean real numbers from a real source, quickly, without borrowing anything that isn't yours. Every one of those assumptions is something you never said out loud. Alignment is the discipline of closing that gap

Modal and Baseten in talks at $15B and $26B, months after last rounds

Two inference platforms are asking investors to reprice the layer that sits between the model labs and everyone using them. The second story is Qualcomm's bid to put an always-on agent in your ears. Modal Labs is in talks to raise at a roughly $15 billion valuation, and Baseten is negotiating a round that could value it at $26 billion. Modal raised $355 million in May at a valuation of $4.65 billion, so the new number is roughly triple it — four months later. Baseten's last round, in June, put

DeepMind says Gemini 4 is in post-training, eyeing an early launch

Google's next flagship is months out, not weeks — and the summit that has dominated the week conspicuously skips the chip question. Koray Kavukcuoglu, Google DeepMind's senior vice president, said Wednesday that Gemini 4 is "in the early phase of post-training" and that he hopes to release it "much earlier" than the end of the year. He was speaking at The Information's AI Agenda Live Summit, in his first interview since taking over the lab. The phrasing is the news: "post-training" is the stage

Qualcomm buys the MoveIt robotics stack and promises to keep it open

The chip vendor bought the middleware that most robots in research and industry are actually planned with — and the promise to keep it open is now the part that matters. Meta shipped the smallest AI hardware at Connect, and OpenAI took its ad business into Southeast Asia. Qualcomm will acquire PickNik Inc., the Boulder company that has stewarded the MoveIt manipulation framework since its Willow Garage days, and says MoveIt 1 and MoveIt 2 will remain open source under their existing license.

DOJ to AI opponents: register as foreign agents or face five years

The Justice Department has put a warning in writing that anyone demonstrating at the direction of a foreign power must register with the government — and the president spent the same fortnight calling opposition to AI and data centers treasonous. A Justice Department release dated September 16 tells "citizens and noncitizens" that anyone acting as an agent of a foreign power in "any public activity, including (but not limited to) public demonstrations designed to further the propaganda or other

Enveda raises $311 million to turn nature's chemistry into drugs

A biotech that reads molecules out of plants and microbes just raised the largest round of the week — and a 2.5B open model showed up to embarrass models twice its size. Enveda has raised $311 million in a Series E led by Catalio Capital Management, at a $2 billion valuation that doubles what the company was worth twelve months ago. The Boulder, Colorado company does not design molecules from scratch; it searches for them. Its PRISM platform uses machine learning and metabolomics to identify co

Amazon hands sellers a Claude plugin so they never open Seller Central

Amazon spent a year treating outside AI agents as trespassers. At its Accelerate seller conference on Wednesday it opened the door itself — and handed the keys to Anthropic. Amazon launched a Selling Partner plugin that lets third-party sellers run their business through an AI assistant instead of the Seller Central portal. Sellers connect either Anthropic's Claude or Amazon's own Quick assistant to their seller account in about 60 seconds, no coding, and from there the assistant can pull listi

Meta's hologram avatars put a photoreal you on video calls

Meta spent Connect this week selling hardware. The announcement that will outlast the hardware is the face it puts on your calls: at Wednesday's keynote the company said its holographic avatars — the productized version of the Codec Avatars research it has demoed since the Orion prototype — are coming to the Meta VR Glasses and to the Ray-Ban Display frames. The avatars are photoreal, they run on a model Meta calls Muse Realtime Avatar, and the first place you will meet one is a WhatsApp call.

Resy banned diners whose AI agents grabbed the tables

Reservations became the first consumer service where delegating to your AI assistant is a terms-of-service violation — and the diners getting banned are the ones the platform is quietly building agent access for. Meanwhile, China's biggest AI image company shipped a studio built for the same one-person crew. Resy has been deactivating the accounts of diners who pointed personal AI agents at its booking system, and it will not say how many. The American Express-owned reservation platform told Re

Meta's VR Glasses land at $1,299 with no headset at all

Meta used its Connect keynote to argue that the computer on your face doesn't have to look like a computer on your face — and that the way out of the smart-glasses reputation problem is to take the camera out. The same afternoon, arXiv got the money to keep being the place AI research gets posted. Meta's next VR device is a pair of glasses, and it costs $1,299.99. The Meta VR Glasses put the displays and sensors on your ears and move everything else — a Snapdragon Reality Elite processor, 128GB
