I tried to get SD-XL to generate an image of a frog with its eyes closed. It refused. I even cranked up the attention on closed to an absurd level, and it seemed to get sassy with me.

    My guess is because this is what they look like when they’re blinking or asleep? It’s transparent, so probably basically looks the same as open eyes and the model probably doesn’t have any closed opaque eyelids to reference as a result. (Although you are correct the AI seems to be getting sassy with you in this image, lol.)

    Frogs have three eyelids: an upper eyelid that blinks to keep their eyes moist, a lower eyelid that stays still, and a third semi-transparent eyelid called the nictitating membrane. The nictitating membrane is used for swimming, camouflage, hibernation, and sleeping.1 It is a thin, transparent eyelid that protects frogs’ large, fragile eyes, making their eyes waterproof and keeping them safe from debris.

      Here are some indications that a frog is sleeping:

      • Limbs are tucked under their body
      • Head is pointed downward
      • Eyes may or may not be covered by a nictitating membrane

      For some species, it can be difficult to tell when they’re resting. In fact, most frogs either sleep with their eyes open (described as “Cataleptic Sleep”) or have a clear or camouflaged membrane covering their eyes.
