Nano Banana (officially Gemini 2.5 Flash Image) is Google DeepMind’s latest image generation & editing model. It’s designed to let users take ordinary photos (selfies, pets, scenery) and transform, remix, or stylize them with high fidelity using natural language prompts and image blending.
MidJourney is developed by an independent research lab founded by David Holz (co-founder of Leap Motion) in 2021. Unlike giants like OpenAI or Google, MidJourney is a smaller, more design-driven team with a very clear vision: to let anyone create stunning artwork using just their imagination and a few words.
