+
+### 性能优化说明
+| 优化项 | 说明 |
+|--------|------|
+| `combine_moe()` | 合并 MoE 专家权重，减少内存访问开销 |
+| `scatter_add` 适配 | 用 `one_hot` + 矩阵乘法替代 NPU 不支持的 `scatter_add` |
+| `use_cache=True` | 启用 KV Cache，避免重复计算注意力 |
+| `no_repeat_ngram_size=20` | 控制重复生成，提升有效 token 效率 |
+| `eager` attention | Ascend NPU 上兼容性最佳的注意力实现 |
+| `float32` 精度 | 保证 OCR 输出质量（float16 存在精度退化）|
+
+### 优化前后对比（Gundam 模式，Ascend 910B，256 tokens）
+| 配置 | TTFT | 生成速度 | 解码速度 | 加速比 |
+|------|------|----------|----------|--------|
+| **全部优化** | 9.757s | 7.95 tok/s | **11.34 tok/s** | **基线** |
+| 关闭 MoE 合并 | 10.805s | 1.68 tok/s | 2.29 tok/s | **4.95x 慢** |
+
+### 不同分辨率模式对比（256 tokens）
+| 模式 | TTFT | 生成速度 | 解码速度 | 适用场景 |
+|------|------|----------|----------|----------|
+| Tiny (512) | **0.214s** | **11.00 tok/s** | 11.06 tok/s | 快速预览 |
+| Small (640) | 0.257s | 10.76 tok/s | 10.83 tok/s | 一般文档 |
+| **Gundam (推荐)** | 9.757s | 7.95 tok/s | 11.34 tok/s | **精度最佳** |
