abstract symbolic representation of the story's core idea (editorial illustration in the spirit of New Yorker or The Atlantic)

The scoreline says this wasn’t a coin flip: Gemini 3.1 Flash TTS Preview wins 27.0 to 24.0, with 88% confidence. That’s not a blowout, but it is a clear result. More importantly, the task breakdown backs it up: Gemini took 2 of 3 tasks, Eleven took none, and the remaining task was a genuine tie.
