MT-EditFlow: Reinforcement Learning for Multi-Turn Image Editing with Flow Matching

Recent breakthroughs in instruction-based image editing have captured significant attention, as models are now capable of handling real-world editing demands with the practicality required by everyday users. However, editing models trained primarily for single-turn edits often break down in multi-turn editing—the natural interactive setting where a user iteratively refines an image based on the model’s own previous outputs. This failure stems from the all-or-nothing requirement, where a single f...
