Anthropic’s Fable 5 can make weirdly fun video games with the click of a button

Anthropic has released Claude Fable 5, the archetypal publically disposable mentation of its closely watched Mythos model. What tin Fable really do? All kinds of things, it turns out.

Ethan Mollick, a notable AI researcher and an subordinate prof astatine Wharton, has been playing around with the exemplary and seems to beryllium having a batch of fun.

In his testing, Fable consistently “outperformed fundamentally each different nationalist exemplary I person utilized by a sizeable margin,” Mollick wrote Tuesday connected his Substack. He added that it was “capable crossed galore problems and produced immoderate startling results — it would enactment up to a twelve hours executing connected multi-page specifications.” 

Perhaps astir strikingly, Mollick utilized Fable to make a assortment of video games — each of which were generated via “one archetypal prompt” successful Claude Code, the researcher says.

Among these, Snake is precisely what it sounds like. You’re a Pac-Man-like snake and you roam astir eating apples. The snake ne'er stops moving, and if you tally disconnected the screen, you die. It’s precise 1980s arcade but, similar galore of those aged games, it’s weirdly addicting. I played it longer than I’d similar to admit earlier remembering I americium a gainfully employed writer and not, successful fact, a serpent who likes fruit.

Then determination was Strata, wherever you’re roaming astir successful a seemingly endless web of subterranean tunnels and the extremity is conscionable to airy arsenic galore lanterns arsenic possible. The graphics look similar a degraded mentation of Myst — they aren’t large — but the information that the crippled exists astatine all, generated from a azygous prompt, is impressive.

Mollick adjacent managed to make Duino, a crippled based connected the Duino Elegies, the celebrated rhythm of poems by German writer Rainer Maria Rilke. I similar the animation present champion — the subordinate is simply a lone fig successful a nocturnal scenery — though determination isn’t overmuch to the gameplay different than walking astir portion Rilke passages materialize connected the screen.

Aside from the assortment of instant games Mollick produced, helium besides utilized Fable to make an isochronic map — a visualization showing however agelong it takes to question betwixt immoderate 2 locations. The accuracy and item is arresting.

The implications are beauteous clear. Software projects that erstwhile required full teams — games, mapping tools, highly analyzable specifications — are present being spun up from a azygous prompt. It’s crushed for vibe coders of the satellite to rejoice. As for founders and operators watching AI capableness curves, it’s a utile information constituent astir however rapidly the level is rising.
