I got access to the preview, here's what it gave me for "A pelican riding a bicycle along a coastal path overlooking a harbor" - this video has all four versions shown:
Of the four two were a pelican riding a bicycle. One was a pelican just running along the road, one was a pelican perched on a stationary bicycle, and one had the pelican wearing a weird sort of pelican bicycle helmet.

All four were better than what I got from Sora: https://simonwillison.net/2024/Dec/9/sora/
