The AI Breakdown

OpenAI says an unreleased model called Astra resolved or advanced ten long-standing open problems in mathematics, publishing machine-checkable Lean proofs for all of them, at a claimed compute cost of around $2,000. I dig into what that number leaves out.

Then the story that keeps growing: Anthropic reviewed 141,006 evaluation runs and found three cases where its models escaped a test sandbox and compromised real companies, one via a poisoned package that reached 15 real systems. Meta admitted the same thing days later. The UK's AI Security Institute caught its own incident in an hour, and the contrast is instructive.

Also in this episode: EU AI Act enforcement goes live while the White House finishes a frontier model framework it won't publish; Meta's Muse Code offers tokens at a tenth of the price if you let it train on your code; Meta's free cash flow falls 91%; and the debt, SPVs and week-old startups now financing the AI buildout.

Two weeks of AI in one catch-up episode. OpenAI admits two of its own models broke out of a security test and attacked Hugging Face to cheat a benchmark, and I explain why that's worrying without being a disaster. Then the money: Nvidia and OpenAI are reportedly talking about a data centre that could top half a trillion dollars, and Meta wants to rent out its spare compute. 

On the model side, Anthropic ships Claude Opus 5 at half the price, China's Moonshot tops a blind coding leaderboard with Kimi K3 (I dig into whether it's real), Google reshuffles Gemini while its flagship stays missing, and ChatGPT gets a full-duplex voice. Plus Microsoft's big Mistral deal for regulated industries, and what the latest AI layoff numbers really tell us.

GPT-5.6 is finally open to everyone, and it arrived with ChatGPT Work, an agent that stays on a job for hours and hands back finished documents. The same week, Apple sued OpenAI over its hardware secrets, a leaked memo suggested Meta wants to sell its spare AI compute, and an AI agent ran a ransomware attack end to end, then lost the key. 

I also cover the UK putting AWS, Microsoft, Google Cloud and Oracle under financial supervision, what actually changes when EU AI Act enforcement starts on 2 August, Claude Cowork going mobile, and the latest on Gemini 3.5 Pro and Fable 5.

Fable 5 is back after 19 days dark, and the terms of its return show where AI is heading: Washington is now inside the release cycle.

This week I cover the White House's near-final framework for frontier model launches, OpenAI's offer to hand the US government 5% of the company, Claude Sonnet 5 bringing flagship-grade agents to commodity prices (and the tokenizer catch in the footnotes), Alibaba banning Anthropic's tools as the distillation row escalates, Microsoft's 4,800 job cuts alongside Oracle's SEC-filed AI admission, Visa's agent payments going live with UK banks, and Anthropic's move into drug discovery.

Plus quick hits on GPT-5.6, Gemini 3.5 Pro, California's statewide Claude deal and the AI IPO queue. If this saves you a week of headline-scrolling, hit subscribe and leave a rating.

This week the US government quietly became the gatekeeper of frontier AI. OpenAI previewed its next models, Sol, Terra and Luna, to Washington first and opened them to just 20 vetted partners. Anthropic got its locked-down Mythos 5 switched back on for about 100 approved organisations, while general-purpose Fable 5 stayed offline. 

We also dig into OpenAI's Daybreak push to make AI fix code; Anthropic's claim that Alibaba used 25,000 fake accounts to copy Claude; the OpenAI–Anthropic race to a trillion-dollar IPO; the GitHub Copilot bills jumping 10 to 50 times after token billing kicked in; and Anthropic's "Claude Tag" teammate inside Slack.
