The Stack
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

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

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

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

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

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

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

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

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

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

Microsoft has put its own model constitution up for public comment, the UN's top human rights official is demanding "cast iron guarantees" on frontier AI, and the network layer under AI clusters just got $205 million of new money behind it. Microsoft published a 37-page

The cyber-safety debate found a dissent inside itself today, the White House picked a side in the camera wars, and some people are knitting their way out of the surveillance net. AI models are "the most potent cyber weapon that has ever been created," Cohere CEO Aidan
