Amazon is introducing an innovative AI Art feature for turning your TV background into an AI generated canvas.
Open the Ambient experience with “Alexa open Ambient” or by clicking on the Ambient shortcut available when you press the Alexa button on your remote.

Now you can use your imagination to prompt, for example “Alexa, create a background of a medieval castle on Mars” (to be fair, that’s the example chosen by Amazon in the press release, I don’t have a good imagination! )

How It Works
Powered by a Titan Image Generator model you can ask for artistic styles like pixel art, oil painting, photorealist or whatever goes through your mind, your Fire TV is ready to oblige. It saves the picture in your Amazon photo account so you can easily share “your” best AI artwork with your friends.

The feature is only available for US users equipped with Fire TV Omni QLED televisions or the second-gen Fire TV Stick 4K Max. It is disappointing for the Fire Cube 4K users, who would love the latest feature to be available on Amazon’s top tier and most capable machine.
