Odincraft

Odincraft is a block world meant to feel like a real place, explored on foot. The current version forms an island about 6 km across in a second: a mountain range, valleys cut by running water, and rivers that follow those valleys to the sea. You can walk, fly, dig and build, with the land drawn to the horizon under sun shadows and haze, and water that flows into any ditch you dig from a river.

It started in Zig as Zigcraft and has been rebuilt more than ten times, in Zig and then Odin. Each new model release gets the same task, which makes it a running benchmark for how far LLM-assisted development has come.
