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 —

The Take — Give shopping agents a name, not a permission slip

Amazon cut Meta's Muse off from Amazon.com over the weekend, and by Monday the argument had settled into the usual shape: open web versus walled garden, scrappy agents versus the store that owns the shelf. I think that framing buries the only question worth arguing about. Amazon is right that an agent should have to say who it is. It is wrong that a merchant's consent should decide whether the person who owns that agent gets to buy something. Those are two different demands wearing one sentence,

Hugging Face ships tokenizers v1 — encoding up to 30x faster

The plumbing of AI got two small releases today — one that stops GPUs from idling on CPU work, one that puts image generation on a laptop-grade footprint. Hugging Face shipped the first major version of its tokenizers library, and the headline number is real: 3 to 30 times faster encoding than v0.23 on a single thread. The tokenizer is the step that turns text into the integer IDs a model reads, and it runs in four stages — normalization, pre-tokenization, the model stage that maps pre-tokens t

AMD crosses $1 trillion as the AI chip trade widens

AMD's stock ran roughly 24% in five sessions and pushed the chipmaker into a club only three other US semiconductor firms have reached. The milestone says less about one product line than about how the market is now pricing AI compute. Advanced Micro Devices topped a $1 trillion market cap for the first time on Monday, hitting an intraday record of $613.92 before closing up about 9% at $610. Reuters counts it as the fourth US chipmaker to cross the mark, after Nvidia, Broadcom and Micron — a cl

M5 Ultra reviews: local AI's ceiling is memory, not compute

Apple's local-AI pitch finally met a measurement harness this weekend. The verdict is not about how fast the GPU draws tokens — it is about how fast the machine can read, and how much it can hold while it reads. Federico Viticci spent four days running the top M5 Ultra Mac Studio with 256 GB of memory against an M3 Ultra with 512 GB and his own RTX 5090 desktop, on identical model files and the same runtime. Tom's Hardware, PCMag and Tom's Guide published their own reviews the same day, and the
