Vibe Minecraft: a multi-player, self-consistent, real-time world model that allows building anything and conjuring any objects. The function of tools and even the game mechanics itself can be programmed by natural language, such as "chrono-pickaxe: revert any block to a previous state in time" and "waterfalls turn into rainbow bridge when unicorns pass by". Players collectively define and manipulate a shared world. The neural sim takes as input a *multimodal* system prompt: game rules, asset pngs, a global map, and easter eggs. It periodically saves game states as a sequence of latent vectors that can be loaded back into context, optionally with interleaved "guidance texts" to allow easy editing. Each gamer has their own explicit stat json (health, inventory, 3D coordinate) as well as implicit "player vectors" that capture higher-order interaction history. Game admins can create a Minecraft multiverse because the latents are compatible from different servers. Each world can seamlessly cross with another to spawn new worlds in seconds. People can mix & match with their friends' or their own past states. "Rare vectors" can emerge as some players would inevitably wander into the bizarre, uncharted latent space of the world model. Those float matrices can be traded as NFTs. The wilders things you try, the more likely you'll mine rare vectors. Whoever ships Vibe Minecraft first will go down in history as altering the course of gaming forever.
