Researchers have developed Stable-Layers, a novel reinforcement learning framework for fine-tuning image layer decomposition models. This method bypasses the need for paired supervision by utilizing feedback from a vision-language model (VLM). The framework, applied to Qwen-Image-Layered, employs Flow-GRPO with LoRA adaptation and a unique two-stage evaluation pipeline to address the challenge of VLM reward signal compression. The resulting Stable-Layers demonstrate improved layer separation, reduced artifacts, and lower reconstruction error on the Crello dataset compared to the original model. AI
