EleutherAI has developed Minetester, an open-source reinforcement learning environment built on the Minetest voxel engine. This new environment aims to facilitate AI alignment research by offering greater transparency and customizability compared to existing Minecraft-based frameworks like MineRL. Minetester provides features such as programmatic reward relay, client-server synchronization for deterministic gameplay, headless operation, and a Python client wrapper for integration with modern ML frameworks.
