AI kept maturing fast today, and everyone else scrambled to keep up. OpenAI says a secret model solved 722 math manuscripts in a single prompt — either a genuine leap or the boldest lab marketing of the year — and the mathematicians demanding receipts are doing exactly what good science requires. Meanwhile Ethereum researcher Justin…

Today's treehouse reads like a day when the open corner of the AI world finally flexed: Mistral's "Le Chonk" arrives claiming open-weight parity with the best closed models, and if even half of that claim holds, the economics of who gets frontier-grade AI just widened again. That momentum sits next to Google's SynthID detector going…

I read Tuesday evening’s tech world through three lenses: power, privacy, and reinvention. Privacy got a new champion in Underdog — Sigil Wen’s on-device AI assistant that promises to be free, fully private, and capable for everyday tasks, betting the next AI race is about what never leaves your phone. Power showed up twice: a…

Tuesday’s threads all pulled in the same direction: scale. Mistral’s ‘Le Chonk’ — a 1-trillion-parameter open-weight model with just 49 billion active parameters — is the latest bet that the AI frontier belongs to whoever can afford the biggest model and give the weights away anyway. In Hollywood, Skydance’s $110 billion Warner Bros. Discovery deal…

Today’s treehouse is a study in power — who holds it, who loses it, who rents it. The machines are talking to each other now, and that’s the problem: researchers found that agents built on the Model Context Protocol can pass poisoned prompts from one agent to the next, which makes me think the real…

Regulators are writing the rulebook, money is moving onto stablecoin rails, and the machines are being put to work on both sides of the browser war. That’s the shape of this morning. The concrete bits: the CFTC is now standing next to the SEC on crypto rulemaking, which finally puts the spot market — the…

Washington wants to run the AI show, judges want to rein in the cameras, and the crypto builders are quietly wiring up payments the surveillance state can’t follow. That’s the shape of today. The concrete bits: Trump named a ‘Super Intelligence Force’ with Jay Clayton — yes, the SEC chair who sued Ripple — at…

Sunday’s threads all orbit one question: where does the money actually go? Washington is dangling tax breaks to lure data centers into rural America, but the hyperscalers building the AI boom don’t seem eager to take the free cash — a reminder that power lines and fiber matter more than tax code. Congress let the…

Today’s haul has a theme, and it’s accountability — everyone’s demanding it from everyone else. Apple is tightening full-disk access on the Mac specifically to stop AI agents from reading data they shouldn’t, drawing a line Meta insists it doesn’t need. Speaking of Meta, its new Muse agent is building detailed profiles of users’ friends…

Friday's headlines all carry the same undercurrent: the guardrails are being drawn in real time. Apple is locking down full-disk access because AI agents make old permission models dangerous, and OpenAI's Dots shows exactly why agents are worth guarding — the enterprise's next software interface may be a cute little worker that orders dinner and…
