**Figureure 1 · : Overview of the Qwen-Image-2.0-RL training pipeline**Figure 1: Overview of the Qwen-Image-2.0-RL training pipeline. Starting from a shared base model, we train two task-specialized RL policies with dedicated reward compositions: T2I generation uses a layered reward design progressing from prompt faithfulness to texture quality to portrait-specific optimization, while editing focuses on instruction accuracy and identity preservation. The resulting teachers are merged into a unified model via on-policy distillation.这张图概括 Qwen-Image-2.0-RL Technical Report 的整体方法流程。阅读时先看模块之间传递的训练信号，再看作者如何把目标拆成可优化的子问题。

The progression Qwen-Image-2.0-Base → Mix-RL → Qwen-Image-2.0-RL demonstrates that RL training improves visual quality over the pre-trained baseline, and that OPD further surpasses mixed RL by avoiding cross-task optimization conflicts. 11这张图/表用于判断 Qwen-Image-2.0-RL Technical Report 的实验收益来自哪里。重点看替换、消融或跨模型设置下趋势是否一致，而不是只看单个最高分。

实验看点

实验部分建议重点看两类证据：一是作者是否把方法收益和更强数据、更长训练、更大模型区分开；二是跨模型、跨数据或跨任务迁移是否还能保留同样趋势。

局限与读法

这篇论文的结论需要结合任务设置、训练数据规模和消融实验一起看；不要只凭单个指标判断它对通用视觉表征的价值。
