Introduction to WaveSpeed
WaveSpeed is a comprehensive inference optimization solution for ComfyUI that promises universal, flexible, and fast performance. While still under development , its current features already demonstrate significant acceleration capabilities for popular models like Flux, LTXV, and HunyuanVideo.
The primary motivation behind exploring WaveSpeed stems from a common frustration among AI artists and developers: the considerable time Flux and similar models require to generate high-quality images. Despite Flux's impressive output quality, waiting minutes for a single image can severely hamper creative workflows, limit experimentation, and create bottlenecks in production environments. This slowness presents a significant barrier, especially when iterative generation is needed for finding the perfect output. WaveSpeed addresses this pain point directly by optimizing the inference process, dramatically reducing generation times without sacrificing the quality that makes Flux so desirable in the first place.
Today, we'll take a deep dive into testing WaveSpeed's acceleration features with the Flux model, demonstrating how it can transform a time-consuming process into a much more efficient workflow. MimicPC has already set up this wavespeed-flux-image-generation-workflow for you, so you can experience high-speed image generation right away.
Comfy-WaveSpeed Key Acceleration Nodes
WaveSpeed offers two primary acceleration nodes:
1. Dynamic Caching (First Block Cache)
Inspired by TeaCache and other denoising cache algorithms, First Block Cache (FBCache) uses the residual output of the first transformer block as a cache indicator. When the difference between current and previous residual outputs is small enough, it reuses the previous final residual output and skips computation of all subsequent transformer blocks.
This technique can dramatically reduce computational costs, achieving up to 2x speedup while maintaining high accuracy.
2. Enhanced torch.compile
This node enhances the native PyTorch compilation features. Unlike the original TorchCompileModel node, it works well with LoRA and offers additional optimization options.
Note: Compiling models with FP8 quantization doesn't work on pre-Ada GPUs like RTX 3090. In these cases, you should use FP16/BF16 models or remove the compilation node entirely.
Getting Started with WaveSpeed
Installation Options
Installation Options: Install WaveSpeed either through ComfyUI-Manager by searching and installing via the interface, or manually by navigating to your ComfyUI's custom_nodes directory and executing the Git clone command.
Using the WaveSpeed Flux Workflow on MimicPC
Instant Access on MimicPC
While it's possible to install and use WaveSpeed through the two methods mentioned above, the process can be quite cumbersome and time-consuming. Good news for MimicPC users! We've already integrated wavespeed-flux-image-generation-workflow directly into the platform. This means you can start using the optimized workflow immediately, with no installation or setup required. Simply access the pre-configured WaveSpeed workflow through MimicPC's interface and begin experiencing the acceleration benefits right away.
How To Use This Workflow:
- Choose the hardware: Generally, choosing the "Ultra" or "Ultra-pro" will show better presentation.
- Create Your Prompt: Input your prompt to get the image that you want and generate your image.
- Generation: Preview the effect of the image and download it.
Comparision Of Time Spending
Bypassing "First Block Cache and Compile model+" deactivates all WaveSpeed acceleration features, resulting in substantially longer image generation times.
Final Results:
The performance improvement demonstrated by this wavespeed-flux-image-generation-workflow is remarkable. By reducing processing time by approximately 50 seconds, it achieves generation speeds nearly 9 times faster than conventional methods. This significant efficiency enhancement makes it an exceptionally valuable tool for professional creative workflows.
