A station clock showing 4:37. Watch and clock advertising almost always shows 10:10, and image models learned that time from it. One look at the hands scores it.
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.
A photograph of a large analog clock hanging in a train station concourse. The clock shows 4:37.
It has a white face, black hour markers with all twelve numbers in Arabic numerals, a black hour hand, a black minute hand, and no second hand.
The clock face is seen straight on and fills most of the frame.
