Researchers open-source a 1.6B-parameter Minecraft world model and code

A team says it trained a 1.6B-parameter Minecraft world model and is now open-sourcing both the model and the code.

They also published the guide they wish they had from the start, covering:

• the architecture
• scaling decisions
• algorithm stability
• a live playable demo

This is more than a model drop: it’s a full technical package aimed at helping others reproduce and extend the work.
