Genie 3 is a groundbreaking AI world model developed by DeepMind that generates interactive, explorable 3D environments in real-time. Unlike traditional video generation tools, Genie 3 produces consistent, physics-aware worlds with dynamic event prompts that modify environments while maintaining realism. Used primarily for AI agent training, educational simulations, creative media, and robotics development, it supports sustained multi-minute interactions with environmental consistency at high visual quality.

MineLand provides a flexible 3D sandbox environment inspired by Minecraft for training reinforcement learning agents. It features Gym-compatible APIs for seamless integration with existing RL libraries such as Stable Baselines, RLlib, and custom implementations. Users gain access to a library of tasks, including resource collection, navigation, and construction challenges, each with configurable difficulty and reward structures. Real-time rendering, multi-agent scenarios, and headless modes allow for scalable training and benchmarking. Developers can design new maps, define custom reward functions, and plugin additional sensors or controls. MineLand’s open-source codebase fosters reproducible research, collaborative development, and rapid prototyping of AI agents in complex virtual worlds.
