## Faster Video Generation Using the `use_ret_steps` Parameter
Using Retention Steps will result in faster generation speed and better generation quality (except for t2v-1.3B).

You can refer to the previous video generation instructions and use the `use_ret_steps` parameter to speed up the video generation process, achieving results closer to [Wan2.1](https://github.com/Wan-Video/Wan2.1). Simply add the `--use_ret_steps` parameter to the original command and adjust the `--teacache_thresh` parameter to achieve more efficient video generation. The value of the `--teacache_thresh` parameter can be referenced from the table, allowing you to choose the appropriate value based on different models and settings.
### Example Command:
```bash
python teacache_generate.py --task t2v-14B --size 1280*720 --ckpt_dir ./Wan2.1-T2V-14B --prompt "Two anthropomorphic cats in comfy boxing gear and bright gloves fight intensely on a spotlighted stage." --base_seed 42 --offload_model True --t5_cpu --teacache_thresh 0.3 --use_ret_steps
```
