How the run ended

The video is finished and passes every hard requirement, but Antigravity stopped the turn with a provider error right after the final encode. The agent never ran its own checks or wrote REPORT.md. The blind panel judges only the video, so the score is unaffected.

Judges’ notes

  • AnthropicSeveral frames pressed against or under geometry, tilted buildings, flat washed look and a hard-to-read drone.
  • OpenAIRecognisable route elements are undermined by flat plazas, crude structures and intrusive foreground geometry.
  • GoogleFeatures a green St. Nicholas dome and river views, but looks hazy and washed out with a flat wall slab at 0 s and an enclosed dark passage at 36.2 s.
