➀ A Minecraft developer named Sammyuri built a functional 5-million-parameter ChatGPT-like AI model (CraftGPT) entirely within the game using 439 million Redstone blocks, capable of basic conversations.
➁ Despite its complexity, CraftGPT faces limitations: responses take hours to generate, outputs are often grammatically flawed or nonsensical, and its context window is limited to 64 tokens.
➂ The project demonstrates Minecraft’s engineering potential, with prior feats including 1Hz CPUs and DOOM-running setups, but remains a technical curiosity rather than a practical AI tool.
