Alibaba just turned its flagship office agent into a showroom for its rivals' models — a move no Western office suite has made yet. Alibaba's Qianwen Office — the enterprise agent suite that opened public beta earlier this month — is the first product to offer Zhipu's GLM-5.3 and DeepSeek's V4 Pro directly, selectable today from the "frontier models" tier on the app's homepage.

A new arXiv paper shows an AI agent modernizing one of the hardest kinds of legacy code — a 250,000-line Fortran weather model — and the validation-first workflow that kept the port trustworthy. Researchers used an AI agent to port CReSS, a legacy Fortran weather simulation code with more than 250,000 lines, to run on GPUs — and the ported version ran a real typhoon simulation 5.1x faster while staying numerically faithful to the original. The workflow, described in a paper submitted to the…

Two countries, two AI publics. A Bloomberg weekend essay from Grace Shao puts hard numbers on the divide shaping everything from product strategy to regulation — and the gap isn't about who uses AI more. Chinese citizens are dramatically more optimistic about AI than Americans, and the difference comes down to who expects to benefit, not who sees more risk.

Anthropic's CEO went where he almost never goes — a long X thread — to make the case for regulation in the middle of the industry's loudest argument about open weights. Dario Amodei took to X Saturday to defend AI regulation and mandatory frontier-model testing, arguing that open-weight models are "nowhere near a sufficient solution" to AI's concentration problem.

Two stories today on how the people making the rules are getting used to AI — one from inside the Capitol, one from the labs shipping the tools. Across the Capitol, lawmakers and staffers are now using chatbots to write speeches and news releases, sort constituent mail, prepare hearing questions, and draft amendments — with almost no rules governing any of it.

Governments have learned that the way to win an argument in 2026 is to be what the chatbot cites. Israel's latest operation shows how far that playbook has gone. Israel has stood up a new, FARA-registered influence operation built specifically to shape what ChatGPT and other LLMs say about Gaza and the IDF — and it is already getting cited.

The week's usage data landed, and the curve keeps pointing one way: Chinese models now move more traffic than American ones — by a wide margin. The catch is in what the numbers actually measure. Chinese AI models have now out-called their US rivals for 15 consecutive weeks, with the top four most-used models on the OpenRouter aggregation platform all coming from China. For the week of August 3–9, the platform recorded 69 trillion tokens of total usage, up 21.5% week over week.

AI labs' hunger for real company data has created a new kind of distressed-asset buyer: data brokers who swoop in when startups shut down or get acquired, offering to buy or license the internal datasets that used to die with the company. Data firms that supply AI labs are driving a growing market for the internal datasets of startups that are shutting down or being acquired, according to The Information.

A new plaintiff has stepped into the growing legal fight over Grok's image generator — and her account of what the tool was used to do is among the starkest yet. A Wyoming woman identified in court filings as "Jane Doe 4" has joined a federal lawsuit against xAI, alleging her stepfather used the Grok chatbot to turn a single childhood photo of her into more than 7,000 sexually explicit images he traded online.

Debian's General Resolution is the free-software world's biggest test of how to live with AI-written code — and the loudest option on the ballot is the worst one. A blanket ban on LLM contributions wouldn't keep AI out of Debian; it would just make sure the AI that gets in arrives undeclared. I think Debian should vote for responsible use, not prohibition.

The biggest guarantee in AI financing just got a lot smaller — and the reason is risk, not strategy. Nvidia has cut its planned financial backing for OpenAI's Ohio data center nearly in half, from a $250 billion guarantee to just under $120 billion, after investors pushed back on the company's exposure, the Wall Street Journal reports.

Anthropic told prospective investors it generated more than $11.5 billion in revenue in the second quarter with positive adjusted operating income — its first profitable quarter by that measure. The numbers, from documents viewed by Bloomberg, land weeks before what reporting has described as potentially the largest IPO on record, and they reset the conversation about whether frontier AI can be a real business. The numbers behind the milestone The scale of the jump matters as much as the…
