Cache-DiT: A PyTorch-native Inference Engine with Hybrid Cache Acceleration and Massive Parallelism for DiTs.

🤗🎉A PyTorch-native Inference Engine with Hybrid
Cache Acceleration and Massive Parallelism for DiTs

🤗Why Cache-DiT❓❓Cache-DiT is built on top of the 🤗Diffusers library and now supports nearly ALL DiTs from Diffusers. It provides hybrid cache acceleration (DBCache, TaylorSeer, SCM, etc.) and comprehensive parallelism optimizations, including Context Parallelism, Tensor Parallelism, hybrid 2D or 3D parallelism, and dedicated extra parallelism support for Text Encoder, VAE, and ControlNet.

Cache-DiT is compatible with compilation, CPU Offloading, and quantization, fully integrates with SGLang Diffusion, vLLM-Omni, ComfyUI, and runs natively on NVIDIA GPUs, Ascend NPUs and AMD GPUs. Cache-DiT is fast, easy to use, and flexible for various DiTs (online docs at 📘readthedocs.io).

(Let's go beyond Cache-DiT) 👉 SGLang Diffusion | vLLM-Omni | Diffusers

🚀Quick Start

You can install the cache-dit from PyPI or from source:

pip3 install -U cache-dit # or, pip3 install git+https://github.com/vipshop/cache-dit.git

Then accelerate your DiTs with just ♥️one line♥️ of code ~

>>> import cache_dit
>>> from diffusers import DiffusionPipeline
>>> pipe = DiffusionPipeline.from_pretrained("Qwen/Qwen-Image")
>>> cache_dit.enable_cache(pipe) # Cache Acceleration with One-line code.
>>> from cache_dit import DBCacheConfig, ParallelismConfig
>>> cache_dit.enable_cache( # Or, Hybrid Cache Acceleration + Parallelism.
...   pipe, cache_config=DBCacheConfig(), # w/ default
...   parallelism_config=ParallelismConfig(ulysses_size=2))
>>> from cache_dit import DBCacheConfig, ParallelismConfig, QuantizeConfig
>>> cache_dit.enable_cache( # Or, Hybrid Cache + Parallelism + Quantization.
...   pipe, cache_config=DBCacheConfig(), # w/ default
...   parallelism_config=ParallelismConfig(ulysses_size=2),
...   quantize_config=QuantizeConfig(quant_type="float8"))
>>> output = pipe(...) # Then, just call the pipe as normal.
