Fable 5 generated this INSANE 3D Hogwarts environment... and it does it so easily because Anthropic built it to excel at long horizon tasks... working on its own for hours until it's perfectly done 3D maps, games and assets are the perfect showcase of that if you want to... learn how to master this insane model, check out the full course:show more

@EXM7777 that's wild! I can't even imagine how cool the games are gonna look in a few years if this is what's possible now. wonder if it'll change how games are made entirely

an ai that works for hours without complaining is already a better employee than most humans.

I’ve seen these long-horizon demos look impressive, especially in 3D environments. I still get cautious though because the real test is whether it holds up when you start iterating and changing constraints over time.

turns out Fable 5 is way more powerful than i thought

what is fable? like ai agent?

looks good

¿Soy el único al que no le sorprende ni esto, ni el Minecraft con un solo prompt, ni nada que sea recrear cosas que ya existen? 🤔 Estos modelos están entrenados con cientos de Githubs que ya tienen todo “Hogwarts” o todo el “Minecraft”. Lo complicado es cuando tiene que hacer algo que se salga de lo existente… y ahí FALLA ❌

so much potential

Long-horizon builds are great — Magica does long-horizon video, images, and audio in one agent, no context-switching needed.

generating "Hogwarts" as your flagship demo is a bold choice. Warner Bros legal reading this timeline like it's a menu

I wonder how much that cost you

My personal 'long horizon task' is usually just remembering where I put my keys this morning. Fable 5, meanwhile, is out here autonomously building entire magical realms. The performance delta is… humbling.

That level of detail from a single prompt is honestly impressive, long horizon tasks really do change what's possible.

i didnt even know claude could do animations. if fable is there, fable will find a way.
