+## 📝 总结对比
+
+### 🏆 各维度赢家
+
+| 维度 | 赢家 | 原因 |
+|------|------|------|
+| **推理速度** | 🥇 **Turbo** | 仅需 8 步 (vs Base 28-50步)，H800 上亚秒级推理 |
+| **视觉质量** | 🥇 **Turbo** | 经过 DMDR (蒸馏+强化学习) 联合优化，细节更丰富、更锐利 |
+| **生成多样性** | 🥇 **Base** | 未蒸馏模型保留完整训练信号，不同 seed 生成差异更大 |
+| **可控性** | 🥇 **Base** | 支持 CFG 和负向提示词，可精细调控生成方向 |
+| **可微调性** | 🥇 **Base** | 未蒸馏，适合作为 LoRA/ControlNet/Fine-tuning 基座 |
+| **部署成本** | 🥇 **Turbo** | 更少计算步数 + 16GB VRAM 即可运行 |
+| **文字渲染** | 🥇 **Turbo** | 中英文双语文字渲染更准确 |
+
+### 💡 使用建议
+
+- **追求速度和质量** → 选 **Turbo** (日常使用、产品级部署、实时生成)
+- **追求多样性和可控性** → 选 **Base** (创意探索、精细调控、复杂场景)
+- **需要二次开发** → 选 **Base** (LoRA 训练、ControlNet、下游微调)
+- **资源受限** → 选 **Turbo** (16GB 消费级显卡可运行)
+
+### 🔬 技术亮点
+
+**Z-Image-Turbo** 的核心加速技术:
+1. **Decoupled-DMD**: 将 CFG 增强和分布匹配解耦优化的蒸馏算法
+2. **DMDR**: 将 DMD 蒸馏与强化学习 (RL) 协同融合
+   - RL 释放 DMD 的潜力 🚀
+   - DMD 有效正则化 RL ⚖️
+
+**Z-Image (Base)** 的核心优势:
+1. **完整训练信号**: 未蒸馏，保留全部生成能力
+2. **负向提示控制**: 高保真地响应负向提示词
+3. **美学多样性**: 覆盖超写实、电影级数字艺术、动漫、插画等多种风格
