One-shotting a Raccoon Heist game using Claude Fable 5
↗
Simon Willison used Claude Fable 5 to generate a complete 3D browser game from a single prompt containing a 2022 tweet's GPT-3 game concept and DALL-E images, with the AI working independently to produce a playable result.
This demonstrates that current AI coding agents can take a vague creative brief and produce a functional, deployable software artifact without iterative human guidance. For engineers, it shows a workflow where AI handles both technology selection and implementation, with the human role reduced to providing initial context and a deployment target.

Claude Fable 5 built a working 3D browser game from a single prompt with two images, choosing Three.js and structuring the project independently.
Willison used GitHub Pages as a live preview mechanism, having Claude commit and push frequently so he could watch progress without running anything locally.
Giving Claude access to an OpenAI API key allowed it to generate textures via gpt-image-2, filling capability gaps by combining multiple AI services in one workflow.
