It's so awesome that I can let my kid paint with Krita and let her enhance the picture with AI live. She wanted to have an AI picture editor on her phone but I didn't like the privacy policy. But Krita AI Diffusion came to the rescue.
After testing it out myself I showed her Krita, the most important tools and how to use layers and before I could say anything she was off to paint a nice landscape. When she was finished I actually got to enable the AI plugin and show her the ropes around that. And after enabling live painting she went ham and added a phoenix and a giant hand.
Hardest thing about it was that she had to describe what she wanted in English. But she's already learning that in school so it shouldn't give her too much trouble in the long run.
Anyways, FOSS rules!
There is one app that runs the model on an iPhone. It’s called “draw things: ai generation“. But you aren’t wrong about AI image generation usually needing a gaming pc or at least a video card with a lot of video ram to hold the model in while it works.
