JamBench - Theme and Description Generation (Claude Code): leaderboard
Metric: L3a runtime pass rate (%): share of generated Godot 4 projects that pass file-integrity and headless compilation checks and then run 30 seconds in headless mode without crashing; Task 1b: the jam theme plus a gameplay description; 50 real Game Jam themes, three runs each; the model writes a complete 2D Godot 4 project from scratch; Claude Code as the agent harness, iterating with the Godot toolchain; higher is better. Source: arxiv.org. Saturation forecast: Around December 2026. 5 models tracked.
