Nvidia AI module found inside Russia's new cruise missile

Ukrainian military intelligence says it pulled an Nvidia Jetson Orin — a module sold for robotics and self-driving development — out of Russia's newest cruise missile, Google researchers argue that frontier models' factual errors are mostly "lost keys" rather than "empty shelves," and Tsinghua open-sourced a code-repair model that tops the open-source leaderboard. Ukraine's Defense Intelligence (HUR) says it found an Nvidia Jetson Orin module inside Russia's new S-71 "Monochrome" cruise…

The Take — Hidden reasoning protects labs, not users

The researchers who pried hidden reasoning out of Claude, GPT, and Gemini are framing their work as an IP story: encrypted chain-of-thought was never the moat the labs pretended it was. I think that's the smaller half of it. The bigger casualty is the safety case for hiding reasoning at all — and that was the only honest reason the labs ever gave us for the secrecy. We covered the mechanics in depth yesterday (cracking the encrypted chain-of-thought in frontier LLM APIs), so the short version.

xAI's Grok 4.6 matches GPT-5.6 Sol on intelligence index

Two frontier releases landed within hours of each other: xAI shipped Grok 4.6 with a claim of parity with OpenAI's GPT-5.6 Sol on a composite intelligence index, and DeepSeek pushed its flagship V4 Pro to general availability. A 3-billion-parameter vision model built to run on a phone rounds out the afternoon. xAI released Grok 4.6, its most capable model yet, and says it matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index — a composite of nine benchmarks where both score 61…

Qwen open-sources Qwen3.8-2.4T-A95B, its first Max-class model

Wednesday's wire: Alibaba opened the weights on its most powerful model ever, Honor put a robotic arm in a phone and sold 400,000 of them before lunch, and Europe's booksellers started refusing suspicious bulk orders. Alibaba's Qwen team open-released Qwen3.8-2.4T-A95B on Wednesday — the first Qwen-Max-class model to ship as open weights, with 2.4 trillion total parameters and 95 billion active in a 512-expert mixture-of-experts architecture.

Attack exposes hidden reasoning traces inside Claude, GPT, Gemini

Two stories frame the day: researchers found a way to pry open the hidden chain-of-thought inside frontier models, and Germany moved to treat Meta's AI glasses the way it treated a spy doll. Researchers from the University of Tübingen, the Max Planck Institute, MATS Research, and security firm Snyk have found a way to extract the hidden reasoning traces of frontier models — and the method turned up the strongest evidence yet that some Chinese open-weight models were trained on US rivals'…

Anthropic names first Head of Claude for Legal

The legal industry is becoming AI's next battleground: Anthropic hired a legal AI founder to run Claude's push into law, a Chinese robotics startup claims a sorting record that beats Figure AI at a fraction of the hardware cost, and AT&T says open models will soon power the majority of its AI. Anthropic has hired Robert Mahari, founder of the legal AI startup Akiva AI, as its first "Head of Claude for Legal" — a sign that the company intends to turn legal work into a serious commercial…

CodeRabbit raises $143M to tame the flood of AI-generated code

The money in AI coding is moving from generating code to governing it: CodeRabbit raised $143 million at a $1.5 billion valuation to help teams keep up with the flood of machine-written pull requests. Elsewhere, Ahrefs shipped an agent workspace for marketers, and some of AI's biggest backers started buying old-school service firms to rewire them. CodeRabbit raised $143 million in Series C funding at a $1.5 billion valuation to help engineering teams manage the explosion of AI-generated code.

Nebius cloud revenue jumps 514% to $575M

The AI compute buildout is still printing growth numbers: Amsterdam's Nebius posted another triple-digit quarter, enterprise AI's missing-context problem pulled in a $63 million bet, and the ChatGPT dog-cancer vaccine story officially became a startup. Nebius, the Amsterdam-based AI cloud company that carries Yandex's international infrastructure business, reported Q2 cloud revenue of $575 million, up 514% year over year — with total revenue of $582 million beating the $557 million analysts…
