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

Just a fun side project. Hooked up Mineflayer (Node.js Minecraft bot) to Nemotron 9B running on vLLM, with a small Python Flask bridge in between. You chat with the bot in natural language and it figures out what to do. 15 commands ed - follow, attack, hunt, dig, guard mode, navigate, collect items, etc. The LLM outputs a structured format ( [action] COMMAND("arg") ) and regex extracts the command. No fine-tuning, no function calling, ~500 lines total. Runs on a single RTX 5090, no cloud APIs. My kid loves it. GitHub: Blog: submitted by /u/Impressive_Tower_550 [link] [comments.
