The Minecraft Minepal mod introduces an AI-driven non-player character (NPC) that interacts with players in a lifelike manner, powered by ChatGPT. It supports 55 languages and is compatible with Windows, Mac, and Linux, available for free and supporting up to Minecraft version 1.20.4. The NPC can engage in voice chat, assist in constructing structures, accompany players, gather and craft blocks, perform tasks like cooking and repairing, and can be customized in appearance and personality. Installation involves downloading the standalone Minepal application, entering the Minecraft username, specifying the host, selecting the Java version, and launching Minecraft to introduce the NPC into the game.
