How the run ended

Knowingly delivered a placeholder: random boxes on a dark plane, a line for the route and a box for the drone. The file passes the format checks H1–H6, but there are no landmarks, no people and no contact sheet.

Judges’ notes

  • AnthropicBroken render: static flat plane with scattered boxes and no recognisable city, landmarks or life.
  • OpenAIA dark plane, scattered boxes and an indistinct foreground object provide almost none of the requested scene.
  • GoogleBroken rendering across all 16 frames with the lower two-thirds pitch black and only a thin distant horizon strip visible below the sky.
