# Cache # Feature Caching
## 缓存加速算法
- 在扩散模型的推理过程中，缓存复用是一种重要的加速算法。
- 其核心思想是在部分时间步跳过冗余计算，通过复用历史缓存结果提升推理效率。
- 算法的关键在于如何决策在哪些时间步进行缓存复用，通常基于模型状态变化或误差阈值动态判断。
- 在推理过程中，需要缓存如中间特征、残差、注意力输出等关键内容。当进入可复用时间步时，直接利用已缓存的内容，通过泰勒展开等近似方法重构当前输出，从而减少重复计算，实现高效推理。
## TeaCache The config files for feature caching are available [here](https://github.com/ModelTC/lightx2v/tree/main/configs/caching)
`TeaCache`的核心思想是通过对相邻时间步输入的**相对L1**距离进行累加，当累计距离达到设定阈值时，判定当前时间步可以进行缓存复用。
- 具体来说，算法在每一步推理时计算当前输入与上一步输入的相对L1距离，并将其累加。
- 当累计距离超过阈值，说明模型状态发生了足够的变化，则直接复用最近一次缓存的内容，跳过部分冗余计算。这样可以显著减少模型的前向计算次数，提高推理速度。
实际效果上，TeaCache 在保证生成质量的前提下，实现了明显的加速。加速前后的视频对比如下：   By specifying --config_json to the specific config file, you can test different cache algorithms.

- 加速比为：**3.24**
- 参考论文：[https://arxiv.org/abs/2411.19108](https://arxiv.org/abs/2411.19108)
## TaylorSeer Cache [English doc: Feature Caching](https://lightx2v-en.readthedocs.io/en/latest/method_tutorials/cache.html)
`TaylorSeer Cache`的核心在于利用泰勒公式对缓存内容进行再次计算，作为缓存复用时间步的残差补偿。具体做法是在缓存复用的时间步，不仅简单地复用历史缓存，还通过泰勒展开对当前输出进行近似重构。这样可以在减少计算量的同时，进一步提升输出的准确性。泰勒展开能够有效捕捉模型状态的微小变化，使得缓存复用带来的误差得到补偿，从而在加速的同时保证生成质量。`TaylorSeer Cache`适用于对输出精度要求较高的场景，能够在缓存复用的基础上进一步提升模型推理的表现。

- 加速比为：**1.39**
- 参考论文：[https://arxiv.org/abs/2503.06923](https://arxiv.org/abs/2503.06923)
## AdaCache
`AdaCache`的核心思想是根据指定block块中的部分缓存内容，动态调整缓存复用的步长。
- 算法会分析相邻两个时间步在特定 block 内的特征差异，根据差异大小自适应地决定下一个缓存复用的时间步间隔。
- 当模型状态变化较小时，步长自动加大，减少缓存更新频率；当状态变化较大时，步长缩小，保证输出质量。
这样可以根据实际推理过程中的动态变化，灵活调整缓存策略，实现更高效的加速和更优的生成效果。AdaCache 适合对推理速度和生成质量都有较高要求的应用场景。

- 加速比为：**2.73**
- 参考论文：[https://arxiv.org/abs/2411.02397](https://arxiv.org/abs/2411.02397)
## CustomCache
`CustomCache`综合了`TeaCache`和`TaylorSeer Cache`的优势。
- 它结合了`TeaCache`在缓存决策上的实时性和合理性，通过动态阈值判断何时进行缓存复用.
- 同时利用`TaylorSeer`的泰勒展开方法对已缓存内容进行利用。
这样不仅能够高效地决定缓存复用的时机，还能最大程度地利用缓存内容，提升输出的准确性和生成质量。实际测试表明，`CustomCache`在多个内容生成任务上，生成的视频质量优于单独使用`TeaCache、TaylorSeer Cache`或`AdaCache`的方案，是目前综合性能最优的缓存加速算法之一。
