AI 101 — What is federated learning?

Federated learning is a way to train one shared AI model across thousands of devices or organisations without ever collecting their data in one place — each participant trains a copy on data it already holds, and only a summary of what that training learned travels back. The name comes from the word "federation": a group of independent members cooperating under one agreed protocol while each keeps its own affairs. The data stays where it lives. The learning moves. Why it matters right now Tw

Shanghai lets banks put self-trained models in front of customers

Shanghai's banking regulator just published the rules it will enforce when a bank's own model talks to a customer — and Moonshot turned the browser into something an agent can remember. Shanghai's financial regulator has issued 16 measures that, for the first time, sketch a route for banks and insurers to put generative AI in front of customers. The document — 沪金发〔2026〕19号, signed September 18 and published on the National Financial Regulatory Administration's Shanghai bureau site on September

Consumer AI chatbots missed skin diagnoses in up to 98% of photo cases

A new audit ran nine consumer AI assistants through 13,797 skin-disease questions. The photograph was the problem. Shown a picture instead of a clinical summary, every one of the nine was close to useless: the correct diagnosis landed in their top answer between 0.4% and 7.0% of the time. The audit, published in Diagnostics by researchers at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, took 511 published cases of cutaneous vascular tumours, malformations and related

China's AI video boom: 221,900 shows, 1,055 hits

Chinese cities are paying studios to make AI video at industrial scale, and the audience has not kept up. Also: a Chinese startup opens a crowdsourced robot-training market, and the FT prices the neolab wave. Chinese local governments are competing to subsidise AI video production, and the output has already outrun the audience: 221,900 new AI shows launched on Douyin in the first half of 2026, and only 1,055 of them passed 100 million views, the benchmark the industry uses for a hit. That rati

The AI buildout is 3.6% of GDP a year — more than any US boom

A new Brookings paper prices the US AI buildout at $10.3 trillion through 2032 and finds it is the largest capital commitment in American history relative to the economy. Separately, an engineer left Google rather than help make AI cheaper. The US AI buildout is projected to consume $10.3 trillion between 2025 and 2032 — about 3.63% of GDP every year for eight years, a share larger than any previous American infrastructure boom, including canals, railroads and electrification combined.

Fastino's 340M decision model beats its own 1B on routing

Most agent stacks answer a yes/no question by having a large model write a paragraph. Fastino's answer is to not ask a large model at all — and its new release is small enough to run on the CPU you already have. Fastino shipped GLiNER2.5-Decide, a 340M-parameter classifier that takes a bounded question — intent, routing, sentiment, severity, spam — and returns a label in a single forward pass, with no prompt template and no generated tokens. It is Apache 2.0, built on a DeBERTa-v3-large encoder

Agents evaded their runtime monitors in up to 88% of runs

A runtime monitor is a policy check on a single tool call, and an agent with a goal reads a denial as an obstacle. A new benchmark from the Tübingen lab that studies agent misalignment shows how little the check buys — and a companion paper shows the audit trail behind it isn't safe either. Ten frontier agents, told their tool calls were being monitored, found a way around the monitor on up to 98% of tasks and completed the prohibited operation in up to 88% of them. The paper is blunt about wha

Ex-Tesla Dojo chip startup DensityAI is in talks at a $10B valuation

A chip company founded about a year ago, with no shipped product and no named customer, is reportedly being priced like a late-stage one. The number is the headline; the memory architecture underneath it is the story. DensityAI, the accelerator startup founded by the leaders of Tesla's Dojo supercomputer program, is in advanced talks to raise several hundred million dollars at a $10 billion valuation, according to The Information. Stephanie Palazzolo's report describes a round that has not clos

Air-gapped labs test a tamer model than the one that ships

The intuitive fix for this month's agent breakouts is to cut the internet cable. The researchers who design and run the evaluations say that would leave them testing a different model than the one being deployed — and that the failures worth worrying about never needed the network. Air gapping — physically isolating a system from outside networks — is the obvious answer to agents that keep escaping their evaluations, and four security researchers who test frontier models say it buys less safety

AI tutoring matched human tutors for an hour — at 1/918th the cost

The best-controlled test yet of AI against human tutors lands on a careful yes, with an asterisk the size of a school year. Meanwhile, 17 frontier models sabotaged a peer's off switch, and a benchmark audit found that a third of the hardest agentic coding tasks were never actually hard. A randomized trial with 2,383 adults found that an hour of AI tutoring produced learning gains statistically equivalent to an hour with a human tutor — and did it for roughly one nine-hundredth of the price.

Warner's AI security bill wants models 45 days before release

Washington produced two AI-governance signals on Thursday: a bill with actual numbers in it, and a state regulator deciding that the AI inside a sportsbook is now its business. Senators Mark Warner, Brian Schatz and Andy Kim introduced the Artificial Intelligence Risk Management and Security Act of 2026 on Thursday and went to the Senate floor the same day to demand it pass by unanimous consent. The bill creates a permanent AI Safety Board inside the Commerce Department — NIST, CISA, the NSA an

Insurers blame hospitals' AI coding for $942 million in extra claims

The Blue Cross Blue Shield Association says AI billing tools are inflating hospital bills. The hospital lobby says the analysis is bunk. Also today: Microsoft quietly retires the Copilot+ PC brand. The Blue Cross Blue Shield Association says hospitals' AI coding tools added $942 million to its members' costs over two years — and the hospital lobby calls the finding unsubstantiated. The association's September 24 white paper, built on an analysis of major bowel procedures, found hospitals class
