Seven PhD students trained a 7B model — and left every log in

Beijing's frontier labs get most of the attention, but the most instructive Chinese AI release this week came from a university project with a student-sized budget and an agent-sized workforce. Seven PhD students at Beijing's Zhongguancun Academy trained a 7B-parameter language model from scratch in one summer, then published everything — code, data recipe, logs, and every intermediate checkpoint. The model is ZGCM-1, a 7.39B dense model released under MIT with a 256K-token context window, aime

Brussels will propose barring under-15s from chatbots and feeds

The AI slowdown debate went global today and every capital answered with its own agenda: Brussels reached for a ban, Berlin for a veto on slowing down, and Nvidia quietly repriced what a single desk AI box can hold. The European Commission will unveil an EU KIDS Act on Thursday that restricts under-15s from social media, video-sharing platforms, online games and — explicitly — AI chatbots and AI companions, according to preparatory documents seen by Politico Europe and Reuters.

Same Qwen3 voice model, 14x faster — hosting is the product now

A YC-backed inference shop just posted numbers showing the model on the label tells you almost nothing about how it performs. Meanwhile, a music startup raised money on the opposite bet: that abundance of AI-generated audio makes human taste worth more. Nari Labs reported the top scores on Coval's voice AI leaderboards, and the sharpest number in the release isn't its own — it's what happens to the model it didn't tune. The YC-backed host serves a 1.7B Qwen3-TTS endpoint at 8.8% word error rate

Apple ships iOS 27. Its new Siri AI is still a beta

Apple's biggest AI release arrived with a "beta" label attached. Meanwhile the people who built the benchmark for AI-run businesses are opening it to everyone, and Manhattan just carried out the largest deepfake-site seizure on record. Apple's long-delayed Siri AI finally shipped today — as a beta. iOS 27, iPadOS 27, watchOS 27 and visionOS 27 went out this morning, with macOS 27 Golden Gate alongside them, and the headline feature in all five is Siri AI: on-screen context answers, drafting and

K2 Horizon 7B beats models 4x its size — and eats your RAM doing it

Three things landed on our desks this afternoon: an independent benchmark pass on Abu Dhabi's fully open model fleet, a security write-up on how far you can push an AI that reads your support inbox, and a paper arguing that judge panels are less reliable than their vote counts suggest. Artificial Analysis has now scored MBZUAI's K2 Horizon 7B at 21 on its Intelligence Index, against a median of 8 for open-weight models of the same size class — and the local-AI community's verdict is that the pl

Tandem Health raises $100M for Europe's AI clinic operating system

Monday afternoon's money went into the least glamorous part of the AI stack — the part with a regulator attached. Stockholm's Tandem Health landed Europe's biggest clinical-AI round to date, Waymo opened its doors in Las Vegas, and Akuity made the case that agents need an identity before they get a production deploy. Tandem Health raised a $100M Series B led by the Scaleup Europe Fund, the €5 billion vehicle the European Commission put EQT in charge of this year. It is the fund's first healthca

The Take — Forget the pause. The fight is over the spec

Every headline this week is about speed: whether frontier labs should slow down, who told them to, and who refused. I think that is the wrong argument to be watching, and the tell is that nobody winning it is the one talking about it. The decision that will shape AI for a decade is not the pace of the next training run — it is who drafts the document that says what "safe" measurably means. A pause is a sentence. A spec is an artifact, it ships, and whoever writes it gets to keep the drafting pen

Trump's answer to the pacing ask: he already has criminal power over the labs

The AI pacing debate stopped being about risk on Monday. Washington's reply to the frontier labs asking for a rulebook was a reminder about the powers already on the books, and from Frankfurt came the counter-argument that Europe is buying the leverage it claims to lack. President Trump spent Monday telling the AI industry it needs no new guardrails, then listing the ones he says he already holds. In an all-caps Truth Social post, he wrote that "the only control or 'guardrails' that AI needs is

OpenAI pays humans to fix ChatGPT's tone, not its facts

404 Media got its hands on the instruction documents behind "Project Lily," the program where outside contractors read real ChatGPT prompts and score the replies. Read past the privacy shock and a sharper story appears: the rubric is a written theory of how a chatbot should behave, and the part it leaves out is verification. Joseph Cox reported Monday that OpenAI is hiring hundreds of contractors to work a stream of genuine user prompts. Reviewers never see an account name, and OpenAI says pers

Superhuman buys Fathom instead of building its own meeting notetaker

Two deals on Monday, one small and one very loud: a productivity suite bought its way into the meeting record, and Elon Musk's AI company dropped the hardest of its claims against Apple. Superhuman acquired Fathom, the Y Combinator-backed AI meeting notetaker, rather than finish building one itself. CEO Shishir Mehrotra said the company had tested an internal notetaker with select users earlier this year and concluded that doing all parts of meeting recording well is far harder than the finishe

Two high schoolers used AI to close a Fields Medalist's open problem

A math preprint that should not have landed this week, a leak about who actually reads your ChatGPT conversations, and OpenAI admitting its chip design ran on models nobody outside can use. Two Oak Park High School students, with a UCLA postdoc as mentor, have posted a 75-page arXiv paper extending the theory of Lorentzian polynomials — the combinatorics framework Fields Medalist June Huh helped build — to arbitrary degree, settling a bounded-ratio question the quadratic case left open.

Agents that run for weeks made Temporal a $12.55 billion company

Two funding rounds on opposite ends of the AI stack today: one selling the plumbing that keeps agents alive, one selling music toys that refuse to prompt a model at all. Temporal raised $550 million in a Series E at a $12.55 billion valuation, and the reason it gives is duration. A year ago the company says most of its customer conversations were about payments, onboarding and fulfillment; now customers want agents that run for days, weeks or months without losing state. That is the same proble
