| # FLOW CACHING FOR AUTOREGRESSIVE VIDEO GENERATION |
|
|
| This repository provides the official implementation of **FlowCache** on **SkyReels-V2** model, a caching-based acceleration method for autoregressive video generation models. |
|
|
|
|
| ## 🚀 Installation |
|
|
| Please follow the installation instructions provided in the [SkyReels-V2](https://github.com/SkyworkAI/SkyReels-V2), as this implementation is built on top of SkyReels-V2. |

|
|
| ## ▶️ Usage |
|
|
| ### 1. Video Generation |
|
|
| Run accelerated generation using FlowCache: |
|
|
| ```bash |
| # FlowCache with KV cache compression |
| bash run_flowcache_kvcompress.sh |
| |
| # FlowCache without KV cache compression (fast) |
| bash run_flowcache_fast.sh |
| |
| # FlowCache without KV cache compression (slow) |
| bash run_flowcache_slow.sh |
| |
| ``` |
| For the allreuse implementation of Teacache, please refer to the official SkyReels-V2 repository. |
