Anthropic’s Fable 5 could make weirdly enjoyable video video games with the clicking of a button

Anthropic has launched Claude Fable 5, the primary publicly accessible model of its intently watched Mythos mannequin. What can Fable truly do? All sorts of issues, it seems.

Ethan Mollick, a notable AI researcher and University of Pennsylvania scholar, has been playing around with the mannequin and appears to be having loads of enjoyable.

In his testing, Fable persistently “outperformed basically every other public model I have used by a considerable margin,” Mollick wrote Tuesday on his Substack. He added that it was “capable across many problems and produced some startling results — it would work up to a dozen hours executing on multi-page specifications.” 

Perhaps most strikingly, Mollick used Fable to create a wide range of video video games — all of which had been generated by way of “one initial prompt” in Claude Code, the researcher says.

Among these, Snake is strictly what it appears like. You’re a Pac-Man-like snake and also you roam round consuming apples. The snake by no means stops shifting, and for those who run off the display screen, you die. It’s very Nineteen Eighties arcade however, like a lot of these previous video games, it’s weirdly addicting. I performed it longer than I’d wish to admit earlier than remembering I’m a gainfully employed author and never, actually, a serpent who likes fruit.

Then there was Strata, the place you’re roaming round in a seemingly countless community of subterranean tunnels and the aim is simply to gentle as many lanterns as potential. The graphics appear to be a degraded model of Myst — they aren’t nice — however the truth that the sport exists in any respect, generated from a single immediate, is spectacular.

Mollick even managed to create Duino, a recreation based mostly on the Duino Elegies, the celebrated cycle of poems by poet Rainer Maria Rilke. I just like the animation right here finest — the participant is a lone determine in a nocturnal panorama — though there isn’t a lot to the gameplay apart from strolling round whereas Rilke passages materialize on the display screen.

Aside from the number of prompt video games Mollick produced, he additionally used Fable to create an isochronic map — a visualization exhibiting how lengthy it takes to journey between any two areas. The accuracy and element is arresting.

The implications are fairly clear. Software tasks that after required whole groups — video games, mapping instruments, extremely complicated specs — are actually being spun up from a single immediate. It’s motive for vibe coders of the world to rejoice. As for founders and operators watching AI functionality curves, it’s a helpful knowledge level about how rapidly the ground is rising.
