[r/LocalLLaMA] I gave my Minecraft bot a brain with local Nemotron 9B — it follows orders like "chop that tree" and "guard me from zombies"

A developer successfully integrated a Minecraft bot with a local Nemotron 9B LLM, allowing it to understand and execute natural language commands such as "chop that tree" or "guard me from zombies." The bot, built with Mineflayer and a Python Flask bridge, supports 15 commands by extracting structured actions from the LLM's output. This project demonstrates a practical application of local LLMs for dynamic game AI, achieved with minimal code and no fine-tuning, running on a single RTX 5090.
