Player builds working AI chatbot in vanilla Minecraft using 445K command blocks — clever approach shrank initial block count from over 1 million, requires no mods, plugins, or datapacks to work
TL;DR
Building neural networks in Minecraft using redstone is a relatively common pursuit, but a clever creator has worked around the limitations of command blocks' available math operations to implement an LLM in just 445,782 blocks, down from over a million in the initial implementation.
Nauti's Take
Packing an LLM into 445,782 command blocks is an impressive demonstration of how far compute logic can be pushed inside a game engine, and a genuinely useful teaching object for anyone who wants to understand transformers. The limit is obvious: the model has no practical use and its answer quality is far below anything running on normal hardware.
Valuable as illustration, not as a tool.
