Genie by Deepmind

Genie creates fully playable 2D game environments with physics, agents, and objectives from natural language descriptions. Game designers prototype concepts instantly while AI researchers explore world model capabilities. The model generates consistent interactive worlds lasting hours from single prompts. Text inputs like 'platformer with lava pits and flying enemies' produce complete levels with collision, gravity, scoring, and win conditions. Latent diffusion maintains world consistency across long play sessions while reinforcement learning agents adapt to player behavior. Multi-modal conditioning supports image+text game creation. Research platform demonstrates generalist world models applicable beyond gaming to robotics and simulation. Procedural generation ensures infinite replayability without manual level design. Evaluation suite measures long-term coherence and agent capabilities. Free research release includes model checkpoints and inference code. Requires substantial compute for training and inference. Experimental - worlds may exhibit inconsistencies during extended play. Primarily research tool.
