+# Adaptive Caching for Faster Video DiTs
+
+This is the official implementation for the paper, [Adaptive Caching for Faster Video Generation
+with Diffusion Transformers](https://adacache-dit.github.io/clarity/adacache_meta.pdf).
+
+## **Introduction**
+
+Generating temporally-consistent high-fidelity videos can be computationally expensive, especially over longer temporal spans. More-recent Diffusion Transformers (DiTs)--- despite making significant headway in this context--- have only heightened such challenges as they rely on larger models and heavier attention mechanisms, resulting in slower inference speeds. In this paper, we introduce a training-free method to accelerate video DiTs, termed Adaptive Caching (AdaCache), which is motivated by the fact that "not all videos are created equal": meaning, some videos require fewer denoising steps to attain a reasonable quality than others. Building on this, we not only cache computations through the diffusion process, but also devise a caching schedule tailored to each video generation, maximizing the quality-latency trade-off. We further introduce a Motion Regularization (MoReg) scheme to utilize video information within AdaCache, essentially controlling the compute allocation based on motion content. Altogether, our plug-and-play contributions grant significant inference speedups without sacrificing the generation quality, across multiple video DiT baselines.

+
+## **Installation**
+
+Please follow the steps in [installation guide](https://github.com/AdaCache-DiT/AdaCache/tree/main/opensora_base#installation) to install Open-Sora baseline.
+
+## **Run inference**
+
+Run our video generation pipeline on a single A100 (80G) GPU as follows:
+- Baseline
+
+  ```bash run_sample_video.sh configs/sample.py```
+  
+- AdaCache
+  
+  ```bash run_sample_video.sh configs/sample_adacache.py```
+  
+- AdaCache+MoReg
+  
+  ```bash run_sample_video.sh configs/sample_adacache_moreg.py```
+
+If running on a new set of prompts, change the prompt path and first generate initial images using:
+
+```bash run_sample_image.sh configs/sample.py```
