I Made Best AIs Rebuild 3 Real Games. One Cost 5 Times More
Two AI models, Opus 5 (Anthropic) and Kimi K3 (Moonshot), were tasked with rebuilding three games: Steep, Hollow Knight: Silksong, and Fall Guys, entirely from scratch using Godot.
Both models initially struggled with fundamental aspects like camera placement, terrain detail, and visual effects, requiring iterative feedback to improve.
Opus 5 utilized a technique of storing the mountain as numbers and layering ridges, while Kimi K3 relied on a system of 16 cones, demonstrating different approaches to simulating terrain.
Neither model employed a physics engine, relying on custom-built solutions for features like ragdoll physics in Fall Guys.
The project demonstrated a significant cost difference, with Kimi K3 costing approximately $37 compared to Opus 5’s cost of around $190, highlighting the efficiency of the AI models.
