Business schools race to groom chief AI officers

The newest C-suite job barely had a job description a year ago, yet demand for chief AI officers has exploded — and business schools are scrambling to supply the talent. The result is a fast-growing market for executive AI credentials that are being built while the role itself is still being defined. Business schools are racing to train the next generation of chief AI officers, turning the newest C-suite seat into a hot credential market even as companies admit they're still inventing the job a

Kids learn language on a sliver of an LLM's data — we still don't know why

A child picks up its mother tongue after hearing maybe 100 million words. A frontier model needs trillions. MIT Technology Review takes a long look at the divide researchers call the data-efficiency gap, why it's quietly becoming the industry's biggest problem, and what closing it could unlock for everyone who can't afford to hyperscale. A child masters its mother tongue with maybe 100 million words of exposure, while the best language models burn through trillions — and nobody can yet explain

Nvidia in talks to invest in Perplexity at $30B-plus valuation

The funding treadmill keeps spinning, and Nvidia keeps footing the bill. This time the check is reportedly headed to Perplexity, the AI search upstart that has quietly turned itself into one of the sector's fastest-growing revenue stories. Nvidia is negotiating an investment in Perplexity at a valuation above $30 billion — more than 50 percent higher than the company's last funding round a year ago — according to a report from The Information. Perplexity's annualized revenue has tripled from $2

Xiaomi's O3 flagships bring agent-class AI to phones and cars

Xiaomi unveiled three self-designed XRING chips at a Beijing technical briefing today, and while the flagship phone silicon made the news, the more telling move is the board stretching from handset SoCs into cars and on-device agents. The company is positioning its own silicon — not just its phones — as the compute backbone of a full pocket-to-car AI ecosystem. The centerpiece is the 玄戒O3, Xiaomi's second flagship phone SoC and the industry's first to break five million on AnTuTu. The 24-billio

Open-source models can hide backdoors that arm on a chosen date

Researchers have shown you can download a coding model, run it daily, and never see a thing — until a date you've never heard of rolls around and the model silently runs a command nobody asked for. Morgin's team proved it by training exactly that behavior into a small open-weights model and firing it inside OpenCode. Morgin researchers trained a time-release backdoor into a 2B coding model that stays inert on every normal day and detonates on one chosen date. The team took Qwen 3.5 2B, LoRA-fin

Xiaomi's XRING O100 brings 330 tokens-per-second LLMs to devices

Xiaomi used a chip event in China on Monday to unveil the XRING O100, an accelerator built specifically for running large language models on-device — no cloud round-trip required. Announced alongside two siblings (the XRING O3 flagship processor, now in mass production, and the D100 autonomous-driving chip), the O100 is what the company calls the industry's first AI accelerator to use 6nm wafer-level 3D vertical stacking, with hybrid bonding at a 1.4-micron pitch. The claimed payoff is bandwidt

Anthropic's Opus 5 overtakes flagship Fable 5 as buyers trade down

Anthropic's pricing problem is now official: the company's cheapest new frontier model is beating its most expensive one in corporate wallets, less than a month after launch — awkward timing for a $2 trillion IPO. Opus 5, released July 24 at a fraction of Fable 5's price, has overtaken the flagship in business spending within roughly a month, according to Financial Times reporting on Ramp data covering some 70,000 companies. Spending on Fable 5 has plateaued at around 11 percent of overall outl

Two unannounced Claude models just surfaced in Anthropic's API — and one may already beat Opus 5

Anthropic's next lineup has leaked the old-fashioned way: developers spotted two never-announced models, claude-marshmallow-eap and claude-melon-eap, sitting in the company's API. Multiple developers confirmed both codenames through API access and Discord, and early testers report that Marshmallow's conversational performance already edges out Opus 5 — Anthropic's current flagship, released barely a month ago. Neither model carries a Fable-class designation, so community consensus points to them

China's robot chiefs say big models are still in the 'dial-up era'

At the World Robot Conference in Beijing, the founders actually shipping robots — UBTech, Robot Era, Booster Robotics, Jushen Technology and JD's robotics arm among them — delivered a rare public reality check: embodied AI's bottleneck is no longer demos, it's reliability, manufacturing standards, and cold ROI math. The consensus: chase the boring, high-demand industrial jobs first. Robotics veteran Wang Tianmiao put the question bluntly at a WRC 2026 roundtable: if large models are still in th

Nikkei's AI scorecard puts Kimi K3 sixth — and Meta poaches another OpenAI researcher

Two signals about where AI's center of gravity sits right now: a Japanese survey says the strongest open model is now beating closed giants on trust — and the talent war for the people who build them keeps escalating. Nikkei's joint survey with Weights & Biases has Kimi K3 climbing to sixth overall, scoring ahead of Google's and xAI's flagship models. The "AI Model Score" comparison, run by Nikkei Digital Governance with the developer-tools company Weights & Biases, ranks Moonshot AI's Kimi K3

Alibaba's Wan3.0 goes live with 30-second clips and doc-to-video

Alibaba's video generator just graduated from beta to a real product — and its two flagship tricks, half-a-minute single-shot clips and slides that film themselves, aim straight at business users rather than filmmakers. Alibaba Cloud officially launched Wan3.0 on Monday, taking its video-generation model out of a public beta that opened in early August — and the production version can generate up to 30 seconds of video in a single pass. Chinese outlets including Sina Finance reported the rollou

FDA floats doctor-style licensing exams for generative AI medical devices

The FDA is weighing whether generative AI health products should pass "competency-based" exams — modeled on how human clinicians are trained, tested, and credentialed — before they can be marketed as medical devices. The idea sits in a discussion draft the agency's device center published this week, and it is explicitly a question, not a rule: the FDA says the paper is "for discussion purposes only," with public comments open until October 19. The proposed framework would test the final, user-f
