+# Edit-R1-Qwen-Image-Edit-2509: A model from UniWorld-V2
+
+This model is a checkpoint (`Edit-R1-Qwen-Image-Edit-2509`) developed using the **Edit-R1** framework, as presented in the paper [Uniworld-V2: Reinforce Image Editing with Diffusion Negative-aware Finetuning and MLLM Implicit Feedback](https://huggingface.co/papers/2510.16888). The **Edit-R1** framework focuses on reinforcing instruction-based image editing through Diffusion Negative-aware Finetuning (DiffusionNFT) and MLLM Implicit Feedback.
