A one-sentence prompt. Claude, the next model, spent two hours in Blender MCP and built the model from scratch — no ready-made mesh. The author calls it the most impressive output so far.
Anshu’s first use of Claude Fable 5.5 was POKERMON, Pokémon crossed with Balatro, one-shot in an hour. Mechanics, art, music and the demo video all came from the model.
Niverg had Claude Opus 5 one-shot a turn-based JRPG. His review: on par with Fable, ahead of the other models he tried, no visual defects on the first pass, and combat that already feels balanced.
Matt Shumer asked Claude Opus 5.5 for a working computer from scratch. It built 277,000 logic gates in JavaScript, an operating system on top, and games on the OS. There is a link. You can run it.
Anshu had GPT-6 Astra one-shot a good-looking 3D game in 45 minutes, on a couple percent of quota. The trick he names is image generation, not a longer prompt.
Lenny Rachitsky told Fable to read his launch post and make a launch video. It ran 46 minutes, asked nothing, found the product logos, and came back with the film.
Matt Shumer had Claude Opus 5 one-shot a game in which every visual and every sound is custom code. Nothing was imported. He says to turn the sound on.
Matt Shumer says Fable one-shotted the entire Hogwarts castle: classrooms, the Great Hall, the Quidditch pitch. Not a facade. The rooms the story actually uses.
