22 leaders signed a frontier-AI control pact. The US, China and UK didn't.

Two things landed on the same Monday: a coalition of middle powers published the sharpest international statement yet on frontier AI control, and a Lean-verified number-theory proof appeared with one anonymous account standing behind it. Finland's president, Alexander Stubb, published a joint statement on Monday — a day before the UN General Assembly's high-level debate opened in New York — demanding that frontier AI stay under human control, and it comes with three concrete asks.

Amazon pledges $20M to the Colorado River without its own water data

Amazon put $20 million into the Colorado River this week — and still won't say how much water its data centers take out of it. Amazon announced Monday that it will spend $20 million on water conservation across the Colorado River basin, as part of a new corporate coalition targeting $100 million over the next two years. The basin supplies 40 million people across the western United States and is in what federal forecasters call an unprecedented drought, with Lake Mead still declining. The money

Cloudflare ships Python Workers GA with native AI bindings

Cloudflare has spent about two years getting Python onto its edge network. As of Monday it is telling developers to build on it for real. Cloudflare has moved Python Workers to general availability, making Python a first-class language on its developer platform — and, for anyone building AI, giving Python code native bindings to Workers AI, R2, D1, Hyperdrive, Durable Objects, Queues and Workflows instead of forcing conversions into TypeScript at the RPC boundary. That last detail is the one th

Meta's Muse assistant shipped with a local zero-day

Meta spent the Muse launch arguing that a personal agent can be convenient and safe at the same time. A macOS security researcher has now shown how much of that promise rested on the word "can." A local zero-day in Meta's Muse macOS app lets an unprivileged process hijack the assistant's dictation traffic — and everything Muse is allowed to touch. Patrick Wardle, founder of the macOS security nonprofit Objective-See, published a proof-of-concept he calls not-a-mused, showing that Muse ships wit

Harvey's gross margin hit minus 50% — so it stopped renting frontier AI

Two arguments about frontier AI landed the same afternoon: customers finally showing what the invoices do to a business, and a lab building a panel it says can challenge its research — just not slow it down. Harvey's gross margin fell from about 50% at the start of this year to minus 50% by June, and only turned positive again after it released Tenet, its own model built on Moonshot's Kimi K3, according to a Bloomberg report. The legal AI company's token usage rose twentyfold over the same peri

Xiaomi releases MiMo-V2.6 and open-sources a 1T-class flagship

Xiaomi finished the training run it put on a livestream: MiMo-V2.6 is now three shipped models, and two of them came out with their weights released the same day. Xiaomi officially released the MiMo-V2.6 series on Monday and open-sourced the weights of MiMo-V2.6-Pro and MiMo-V2.6-Flash, alongside the technical report, the RL training environment, the training code, and a 9B distillation built on Qwen. Pro is the flagship — native multimodal, a 1M-token context window, and listed at more than a

SoftBank's SB Energy delays a $50B IPO as investors balk

The first public price check on the AI data-center build-out came back too high for buyers, and a Russian lab put a from-scratch model on the open market the same day. SoftBank's SB Energy has delayed the data-center IPO it had planned for this month after investors pushed back on a valuation above $50 billion, the New York Times reported Monday. The company filed its S-1 on September 1, targeting a Nasdaq listing and a raise of $5 billion to $7 billion, plus a Japanese retail tranche of up to

New York starts registering frontier AI developers in November

Two rule-writing moves and one adoption number landed the same afternoon: New York put dates on a state AI safety law, a Gates-convened coalition named who today's models leave out, and Meta's Muse turned out to be the fastest-growing consumer AI launch anyone has measured. New York will start registering large frontier AI developers in November and hold them to the RAISE Act's requirements from January 1, 2027 — the first US state to put a full compliance calendar on a safety framework this br

OpenAI wants Washington to lead on global AI standards

Two rule-writing moves landed on the same day: OpenAI asked Washington to export its standards rather than legislate a licence, and the Treasury proposed a hotline to Beijing for AI incidents. OpenAI published a Global Affairs post on Monday calling for the United States to lead an international effort to write global technical standards for frontier AI — including standards for recursive self-improvement — and stated for the first time in writing that fully autonomous self-improvement "should

Fable 5's median thinking per call fell 50% in August, an audit finds

A developer spent six weeks logging everything Claude Code sent and received. The result is the most detailed measurement yet of what frontier models actually deliver to paying users — and it does not match the benchmarks. Fable 5's median invocation carried 123 thinking tokens, and 39.2 percent of invocations carried none at all, according to a six-week forensic audit published by developer Lon Lundgren under the title "The Inference Gap." The corpus is not a toy: 43,261 discrete Fable 5 invoc

Europe puts a data centre energy label on the grid, California sends the bill

The European Commission proposed a mandatory A-to-G sustainability label for data centres, with the first labels expected to appear in 2027. The delegated regulation, published Monday, requires operators of facilities of 500 kW or more to disclose how efficiently they use energy and water, how clean their electricity is, and whether they can hand waste heat back to the local grid — plus information on how their water use sits against water stress in the area. Smaller sites can adopt the label vo

Grok 4.7 ships at 4.6's price — and a hardened safety stack

xAI's latest flagship landed this morning with the price left untouched, and New York turned its AI safety law into an operational deadline with dates attached. SpaceXAI released Grok 4.7 today, priced identically to Grok 4.6 at $2 per million input tokens and $6 per million output tokens. The company says the model was built on a larger base and put through longer-horizon reinforcement learning aimed at tasks that take hours rather than minutes, with the gains showing up in self-verification —
