Self-Distillation Policy Optimization via Visual Feedback: Bridging Code and Visual Artifacts

In three linesVisual-SDPO, a self-distillation framework using visual feedback, improves code generation for visual artifacts (charts, web pages, slides). The method traces detected visual defects back to responsible code statements and amplifies distillation signals on those statements. On ChartMimic, Design2Code, and AeSlides benchmarks, it gains +10 absolute points over zero-shot and +2.4 over GRPO.
