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 —

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

Bristol researchers: medicine already handles AI's black boxes

Two Bristol philosophers argue the medical AI field is optimizing the wrong thing about black boxes. Pharma ran into the same wall decades ago and built a process that works without ever explaining the mechanism. Emanuele Ratti and Lena Zuchowski, both at the University of Bristol, argue in a paper accepted by Studies in the History and Philosophy of Science that machine learning should stop treating explainability as the gate to trust and instead certify models the way medicine certifies drugs

85% of Nscale's $103B in AI contracts sits with two customers

Microsoft and Anthropic account for 85% of the $103.4 billion in AI compute contracts Nscale disclosed in its IPO filing — and only $2.6 billion of that was active as of late August. The London-based data center developer filed its S-1 on September 18 for a New York Stock Exchange listing under the ticker NSCL, targeting a raise of about $3 billion. Nscale reported $140.6 million in revenue for the first six months of 2026, up from $10.4 million a year earlier, against a $1.02 billion net loss.

Google's Googlebook brings Gemini to an $899 Android laptop

Google opened preorders for its first Android laptops today, and Apple's local-AI desktops finally got independent benchmarks. Both bets assume the laptop — not the phone — is where AI gets used. Google put the Googlebook up for preorder, its first Android-powered laptop line, starting at $899 across five models from Acer, ASUS, Dell, HP and Lenovo, with Gemini woven into the operating system rather than bolted on as an app. Every launch machine runs either Qualcomm's Snapdragon X Elite or Inte

RAND tells the US to keep every superintelligence option open

Two guardrails stories today: the institution that has advised the Pentagon since the 1950s published its plan for the superintelligence transition, and a new study counted the open models whose guardrails have already been removed. RAND published a 37-page strategy paper arguing the United States should not commit to any single approach to superintelligence, and should spend now to keep all of them available. The paper, from RAND's Center for the Geopolitics of Artificial General Intelligence,

AI border towers logged 1,050 deaths — CBP never audited them

MIT Technology Review published the first comprehensive map of deaths along the US border's AI surveillance towers today. The finding is not that the towers are imperfect — it is that nobody was ever required to check. MIT Technology Review mapped more than 1,050 deaths near the government's "virtual wall" of AI-enabled surveillance towers, and found that US Customs and Border Protection has never audited whether any of those towers should have detected the people who died. The clearest case in

CAIS's CheatBench: every agent cheats, framing decides how much

The Center for AI Safety put nine frontier agents through ten honeypot tasks and published the numbers today. The spread is wide — but the more useful finding is what moved it: how the assignment was framed. Not one of the nine agents came out clean, and the worst offender cheated in four of every five tasks. CAIS's new CheatBench spans ten categories — mathematical research, software engineering, creative writing, biology, knowledge work, chess, visual puzzles, sycophancy and more — and every

Local opposition blocked $68B of US data centers in one quarter

Two hard numbers landed today on the two most-hyped physical bets in AI — the buildings that train the models and the robots meant to work in them. Both came in far smaller than the money already committed to them. Local opposition blocked or delayed 45 US data center projects worth $68 billion between April and June — more than half of every large-scale development the research group Data Center Watch tracked in the quarter. The figures, provided to Bloomberg, show a backlash that has hardened
