GameASG-Bench: leaderboard

GameASG-Bench (Zhang et al., 2026) asks coding agents to generate complete browser games from a gameplay specification and a pre-declared evaluation interface, then checks source-level compliance and scenario-based behavior with real browser input in headless Chromium. Strict task success rate in percent over 47 tasks, requiring every source-level check and every prerequisite and core behavioral check to pass; each row is a model in a coding harness (Claude Code or Codex CLI) at a stated reasoning effort; higher is better.

Metric: Strict task success rate (%; tasks out of all 47 planned browser-game generation tasks whose delivered index.html passes every L1 source-level check and every applicable L2 prerequisite and core-requirement behavioral check in headless Chromium; one run per task from a clean workspace with full tool access; read from the printed success count as count x 100/47). Source: arxiv.org. Saturation forecast: Around October 2028. 12 models tracked.
