Genie 2 is a revolutionary AI world modeling tool that uses an autoregressive latent diffusion model to generate fully playable, action-responsive 3D environments from a single image prompt. This technology supports realistic physics simulations, dynamic lighting, responsive object interactions, and complex character animations. The generated worlds can be manipulated in real-time, making Genie 2 an invaluable tool for rapid prototyping in game development, AI research, creative design workflows, and environment testing.

Simple Playgrounds provides a modular platform for building interactive 2D grid environments where agents can navigate mazes, interact with objects, and complete tasks. Users define environment layouts, object behaviors, and reward functions via simple YAML or Python scripts. The integrated Pygame renderer delivers real-time visualization, while a step-based API ensures seamless integration with reinforcement learning libraries like Stable Baselines3. With support for multi-agent setups, collision detection, and customizable physics parameters, Simple Playgrounds streamlines the prototyping, benchmarking, and educational demonstration of AI algorithms.
