arXiv:2606.27608v1 Announce Type: cross Abstract: We present Qwen-Image-2.0-RL, a post-training pipeline that applies reinforcement learning from human feedback (RLHF) and on-policy distillation (OPD) to improve both the visual quality and instruction-following capability of the Qwen-Image-2.0 diffusion model. To provide reliable reward signals, we construct task-specific composite reward models by fine-tuning vision-language models with a pointwise scoring paradigm and chain-of-thought reasoning. For text-to-image generation, the reward models cover alignment, aesthetics, and portrait fidelit
The continuous advancements in AI, particularly in diffusion models, necessitate more refined post-training pipelines to optimize performance and align outputs with human preferences amidst rapid development cycles.
Improving the visual quality and instruction-following capabilities of diffusion models through RLHF and OPD is crucial for creating more robust, controllable, and commercially viable AI generative art and design systems.
This advancement introduces a more sophisticated and reliable method for fine-tuning diffusion models, leading to higher quality outputs and better model alignment with specific objectives like aesthetics and portrait fidelity.

- · Companies relying on manual image creation subject to competitive pressure
The quality and reliability of AI-generated images will significantly improve, reducing the need for extensive manual post-processing.
Enhanced control and fidelity in image generation could accelerate the adoption of AI across various creative and commercial sectors, potentially displacing some traditional roles.
The development of highly specialized and controllable generative models might lead to new forms of intellectual property disputes over AI-generated content and its origins.
