Wealthy US Families Are Paying $75,000 a Year for AI to Teach Their Kids

Schools like Alpha School and Forge Prep are charging wealthy US families premium tuition for AI-driven tutoring instead of traditional teaching — just as separate research finds AI use is quietly dragging down exam performance in ordinary classrooms.

The UK's Financial Regulator Says It's in an "Arms Race" With AI — What That Means for You

The FCA wants new powers to regulate ChatGPT, Claude and Gemini after finding that a fifth of UK adults are open to using them for financial decisions — a use case that currently sits entirely outside financial regulation.

Anthropic Hid Code in Claude Code to Detect Chinese Users — Here's What It Did

A security researcher found that Claude Code had been secretly checking whether users were in China since April, hiding the signal inside ordinary text. Anthropic calls it an abandoned anti-fraud experiment; Alibaba has banned the tool internally.

A Fanfiction Community Built Its Own AI Detector. The "Proof" Isn't Proof

A fan community found a hidden code Claude can leave behind when its output is pasted straight from the chat window, and built a tool that flags any story containing it. The method is real — but it shows far less than accusers claim, and it's already been used to go after writers who deny wholesale AI use.

The AI week in 32 stories (27 June – 6 July 2026): Washington starts gating who gets frontier AI, and the bill for the boom shows up everywhere

A packed stretch: the US government asked OpenAI to gate GPT-5.6 before launch while quietly restoring a chosen few to Anthropic's Mythos, Apple raised Mac and iPad prices on an AI-driven memory shortage, and Google's own report showed its electricity use jumping 37% in a year. All 32 stories we covered, grouped and in plain English.

Anthropic just launched a science tool for researchers — and said it plans to develop its own drugs

Anthropic's new Claude Science app is pitched as a research workbench for scientists. But at its launch, Anthropic told reporters it plans to go further and develop medicines of its own, putting it in a three-way race with Google and OpenAI to get AI directly into the drug-discovery business.

Google's electricity use jumped 37% in a year — and AI is why

Google's annual electricity consumption rose 37% in 2025, its largest increase ever, driven by the AI data-centre buildout. Its own report is unusually frank: efficiency and clean-energy deals are real, but they are not keeping pace.

OpenAI floats giving the US government a 5% stake — here's what it means

OpenAI has reportedly proposed handing the US government a 5% ownership stake, and wants rival AI firms to do the same. The talks are early and unsigned, but they mark a striking shift in how Washington and the AI industry see each other.

AI impersonated 112 UK public figures — and people found it more convincing than the real thing

A UK study asked an AI to impersonate 112 real public figures from Question Time. Participants rated the AI's answers as more authentic, coherent and relevant than the politicians' own words — a finding the researchers call a "dire" warning.

The US has lifted its ban on Anthropic's newest Claude models — and shown its hand on how AI gets policed

Three weeks after the US government forced Anthropic to pull Claude Fable 5 and Mythos 5, the export controls are gone and Fable 5 returns worldwide on 1 July. The more important story is what the resolution reveals: why the models were pulled, that weaker models could do the same thing, and a new, formal role for government in vetting frontier AI before it ships.

Why your AI chatbot keeps giving everyone the same answer

Ask ChatGPT, Claude or Gemini for a random number between 1 and 10 and you'll almost always get 7. It's a symptom of something an award-winning study calls the "Artificial Hivemind" — the tendency of large language models to converge on a narrow band of predictable answers, and on the same answers as each other. Here's why it happens, and what to do when you actually want variety.

NotebookLM can now turn your documents into 60-second videos

Google's research assistant NotebookLM is adding Short Video Overviews — 60-second vertical clips generated from your own sources. Here's what they are, who can use them yet, and whether a bite-sized AI video of your notes is actually useful.
