Made with Flux 3
Prompt: A tiny mouse running a miniature Italian restaurant out of a hole in a brick wall — checkered tablecloth on a matchbox table, a birthday candle chandelier that is suspended from ceiling with thread, and a thimble of tomato soup for the guest. Soft warm light, macro photography style, shallow depth of field. Suggested Presets to Help You Get Started Sometimes the hardest part of creating is getting started. Meta AI now includes a presets panel with suggested prompts to help inspire you. One tap restores an old family photo, lets you see yourself with trending hairstyles, or reimagines you as a claymation character or a 16-bit video game hero. Whatever you create, it’s easy to share with friends across Meta’s apps so they can try the same preset on their own photos.
