Most image-to-image generators create one new result from your input and a prompt in a single pass. Across several rounds the subject, composition, and details drift, and there is no history to fall back on. FastImg is built for continuous editing instead: every step builds on the previous result, keeps an editing chain you can undo and branch, and holds the subject consistent while you keep refining.
