GAME OVER

No entries match that search.

Model labels show the model that actually ran. Stats are wall time and token counts from harness transcripts where available. Phase 2 entries use Claude Code pointed at OpenRouter. Phase 3 entries use Antigravity with Gemini. The Grok Bot entry was written in-chat from the same short prompt (no peeking). The gpt-6 Codex cards are API-key reruns. Their cost is OpenAI's published Standard rate card applied to captured response usage. Cursor Cloud costs, where filled, are the dashboard chargedCents sum. HTML size is the entry file as served. A dash means the run did not record that number.
