Developer Felix Rieseberg utilized the Fable 5.2 model to generate a first-person shooter game from scratch. The process relied on a single prompt without any further human intervention or additional guidance throughout the development cycle.
The AI autonomously handled the creation of all game assets, including 3D models, textures, and sound effects. It also constructed a complete game environment, resulting in a functional level that features modern graphical fidelity.
The entire generation process took approximately eight hours to complete. During this time, the model processed 445 million input tokens and generated about 2.7 million output tokens, with a significant portion of the input data managed via caching.
The total cost of the experiment reached approximately $550, based on API usage fees. The project is currently available for public testing, allowing users to experience the generated game directly through an online interface.
