Mica v0.1 4B playing a real Minecraft 1.20.4 server. Video attached. How it works - Each step the bot's live game state (inventory, nearby blocks, entities, last result) is written out as text. - Mica scores the candidate commands and picks the next one. It never generates text. It reads the probabilities of the answer label tokens, so output tokens are 0. - The chosen command is executed in the game with Mindcraft's skill library (Mineflayer bot). Run - 23 decisions from an empty inventory to an iron pickaxe: logs, planks, crafting table, wooden pickaxe, stone, stone pickaxe, furnace, iron ore, smelting, iron pickaxe - About 90 to 150 ms per decision - llama.cpp, Q5_K_M, RTX 3090 About the video - The right panel shows each decision as it happened: the candidates, Mica's probabilities, the pick, and the result. Every step is also listed in the history feed. - Long actions (walking, mining, smelting) are sped up, with the speed shown on screen. Back-to-back retries are shortened in the edit. - The HUD and the crafting/furnace screens are drawn from the bot's logged inventory.
