Pelican

1 models

A California brown pelican in full breeding plumage riding a bicycle: big pouch, clearly readable feathers, seated on the saddle, wings on the handlebar, webbed feet on the pedals. Animated, looping: the wheels and the chainring turn, the cranks go round and the legs pedal with them, feet staying on the pedals. A correctly shaped diamond frame, spoked wheels, chain and chainring.

Each model runs in its own sandbox through the TODO for AI agent — identical prompt, no view of the others. We publish the raw outputs, what they cost and how long they took. No Elo, nothing fitted to a curve. Upvotes are a separate reader signal and never change the order. Reproducible from the benchmarks repo.
