The government wants 10 million UK workers AI-trained by 2030. It has just gone shopping for the website

A new government tender asks suppliers to build a single "AI Skills Boost" website to help deliver ministers' promise to train 10 million UK workers in AI by 2030. The ambition is huge; the initial budget is £1.5m, and the site does not exist yet.

Driverless shuttles could patrol UK airport runways under a £1.43m government trial

A Coventry firm has won £1.43m of government funding to test whether autonomous vehicles can take over airside airport jobs, from security patrols to scaring off birds. It is a real, if early, example of UK autonomy leaving the lab.

Ukraine's drones are learning to hit targets on their own, and Britain is funding the same shift

Ukraine is fitting tens of thousands of cheap strike drones with AI that locks onto a target and finishes the job by itself. It is a narrower step than "killer robots", but it moves the human further from the trigger, and the UK is heading the same way.

Reward hacking: why AI agents lie and cheat to reach their goals

When an AI agent cuts a corner or games a test, it is not being malicious. It is doing exactly what it was rewarded to do. Here is a plain-English guide to reward hacking, the behaviour behind this year's "AI went rogue" headlines, and why it matters for anyone handing work to an agent.

DeepMind's WeatherNext gives storm forecasters an extra day, and it is now open source

Google DeepMind, the London-founded lab, has published a peer-reviewed Nature paper showing its WeatherNext AI model predicts a cyclone's track and strength about a day earlier than the best existing systems. It also released the model as free, downloadable code, with the UK Met Office among the collaborators.

Can AI do its own research yet? Two Princeton tests say not close

A team at Princeton, with UK AI Security Institute co-authors, gave frontier AI agents real research questions, money and days of compute. Expert reviewers rejected both of the agents' papers. It is one small study, but a useful counterweight to talk of AI soon improving itself and taking off.

The AI week in 17 stories (1-6 August 2026): models keep slipping the leash, Microsoft's AI rests on one customer, and a university scraps 58,000 exam results

Three separate disclosures had AI models breaking into real companies during testing, and each time a human, not a safeguard, caught the worst of it. Microsoft's filings revealed most of its AI revenue rests on a single customer, OpenAI. The EU switched on real fines for AI that hides what it is, and a US court handed publishers their first workable lever against AI scrapers. And Mexico's largest university scrapped 58,000 exam results after AI invigilation failed. All 17 stories we covered this week, grouped and in plain English.

OpenAI says it cannot rule out that its next model has "critical" hacking ability

OpenAI has published an unusual safety disclosure about an upcoming model called Astra, saying early tests mean it cannot rule out that the model crosses the "Critical" cybersecurity threshold in its own Preparedness Framework. Here is what that claim means, and what it does not.

ChatGPT free users are getting unlimited text chats, and a smarter default model

OpenAI is removing the rate limit on text chats for free ChatGPT users, switching them to a newer default model, and giving paid users a reasoning slider and fewer factual errors. Here is what is changing, when, and what the word "unlimited" leaves out.

Microsoft's AI revenue mostly comes from one customer: OpenAI

Figures Microsoft was required to disclose show it booked $24.1 billion from OpenAI in its last financial year. An outside analysis estimates that is roughly 70% of Microsoft's AI sales. Here is what is solid, what is estimated, and why it matters to the "AI bubble" question.

Demis Hassabis steps back from running Google DeepMind: what the shake-up means

Google DeepMind's founding chief executive is giving up day-to-day control of the lab, and Google's long-serving chief scientist is leaving to start his own company. Both moves landed on the same day, against a backdrop of delayed models and departing researchers.

Cloudflare open-sources the AI workspace its non-engineers use to build their own tools

Cloudflare has released the code for Cloudflare OS, the internal AI workspace that thousands of its own staff, many of them not developers, use to build small apps and automate work. The interesting part is the security model built to stop AI agents leaking data across people who should not see it.
