Two months ago I hosted a small experiment: the same gut-biotics brief handed to a couple of AI tools, every output kept as-built. Biotics is a personal interest of mine — that's why I keep reaching for it as a test, technical enough to stress a model and familiar enough that I can tell when it gets the science wrong. The best result back then was a static page — tabbed sections, a few fade-in animations, competent and flat. You can still open those originals and the write-up that went with them.
This week I gave the same subject to a current frontier model and got back something I couldn't have hosted in April: a playable 3D world. I didn't bother re-running Copilot this time — it hasn't moved enough since to be worth the comparison, so this is really one lineage measured against its own past.
Play it before you read on. The microbes are real — Bifidobacterium rendered as the branched Y-shape it's named for, Saccharomyces boulardii as the budding yeast it actually is — and the definitions follow the ISAPP consensus statements down to the detail that postbiotics are non-living and that an isolated metabolite like butyrate sits just outside the definition.
The leap
The earlier outputs were all pages, and what separated them was how well each tool used the medium. What came back this week is a different kind of object: a real-time flythrough with a game loop you can lose, audio generated in the browser, and a set of organisms each modelled with its own geometry, all of it staying coherent as you move. That is not a styling decision, and it took eight weeks, not the year I would have guessed.
What's striking is the coordination more than the polish. The model held the science, the 3D, the game state, the sound and the performance fallbacks together at once, without being told how they connected. The two links above are the clearest measure of how far the ground shifted.
Then they switched the model off
The model that built this is called Fable. On 12 June 2026, at 5:21pm Eastern, Anthropic received a US government export-control directive ordering it to suspend all access to Fable and its sibling Mythos — its two most capable models — for "any foreign national, whether inside or outside the United States," including the company's own foreign-national staff. To comply, Anthropic disabled both models for every customer; its other models stayed up. The order came three days after the models launched. TIME, Bloomberg and CNBC reported it the same week.
The stated trigger, per the company, was a reported "narrow, non-universal" jailbreak — a way of getting the model to read a codebase and point out its security flaws, a capability the company notes is already available from competing systems. Anthropic said it disagreed that a narrow jailbreak should ground the recall of a model deployed to hundreds of millions of people, and that the same standard applied industry-wide would halt new releases everywhere.
The most safety-hardened model the company had shipped was pulled, days into its life, over a method for getting it to analyse code — close to the same capability that builds something like the game above. As I write this, the public can no longer run the model that made it.
This is the world we live in now
Two things here are moving at very different speeds. The capability went from a static page to a playable world in two months. Everything around it moved faster: a directive issued at 5:21 on a Friday and met that night, a frontier model live for seventy-two hours and then dark, national-security authority reaching a consumer product before most people had heard its name.
You can think the recall was right or wrong, and Anthropic and the government clearly don't agree, and the speed on both sides would still be hard to ignore. Building has got fast enough that a weekend experiment looks dated in eight weeks. The reaction has got fast enough to switch the tool off between a Tuesday launch and a Friday evening.
This is one artifact, so it's an anecdote rather than evidence, and I'd say so either way. But the dates and the directive are on the record and linked above. Play the game, read the order, and judge the distance between how fast we can now build and how quickly that ability becomes something governments move to contain.
What you're left with is an odd object: a small game about the gut, made in an afternoon by a model you couldn't run a week later.
The run is hosted as-built; the directive is Anthropic's published statement, dated 12 June 2026.
