JamBench - Script Completion (Small Projects): 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 2 code completion: 100 benchmark projects with small code bases (under 4K lines), each manually verified playable; 30 to 50% of the .gd script files are removed and must be rewritten; direct generation, the model writes every file in one pass; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 8 models tracked.
