One sentence, no details: a crawfish boil in a Louisiana backyard. Everything else is the model's own knowledge of the event, and a crawfish boil has a well-known look that a checklist can score.

Misses beyond the checklist: plated restaurant service, cutlery, a seafood platter, or a clambake on a beach.
On the models. Nano Banana 2.1 and Nano Banana 2 emit image and text and run as ordinary chat models; Seedream and the Flux models emit only an image and go through OpenRouter's images endpoint. Nano Banana 2.1 thinks at minimal effort by default; a round run at high is a separate round and says so in its batch label.
