Modal Challenge Winner (378 teams) · TreeHacks · Feb 2026

The team typed one sentence describing Minecraft. Overnight, 200 AI assistants wrote code side by side until they had rebuilt the game from scratch.

Why it won: AI coding tools normally work one step at a time, with a human approving each move. The team's bet was that hundreds of agents could run all night with nobody watching, as long as the system kept them all pulling toward the same goal. Keeping 200 independent coders from wrecking each other's work is the real invention; Minecraft was just the proof.
