Consistent Diffusion Using the create-react-app framework, users can generate images using the WebGPU demo, an online application. Users of the most recent version of Chrome must activate the “Experimental WebAssembly” and “Experimental WebAssembly JavaScript Promise Integration (JSPI)” flags in order to access the application. Users must also have JavaScript enabled.
To create an image, the program goes through a sequence of inference processes, each of which takes about a minute, plus an additional ten seconds for the VAE decoder to produce the image.
It is important to note that the procedure can lag by about two times when DevTools is active. Because the CPU performs better and produces more accurate results than the GPU, the UNET model—which generates images—only uses the CPU.The recommended minimum number of steps for acceptable results is 20, but 3 steps will do for demonstration purposes.
Because the model files are cached, there is no need to download them again.With the ability to load the model, initiate the image generating process, and evaluate the outcome, the application offers a user-friendly interface.
An FAQ section with troubleshooting instructions is available to handle specific situations.Some operations are incomplete since onnxruntime’s webgpu implementation is still in its early stages, even though it runs on a GPU.
Performance is impacted as a result of the constant data flow between the CPU and GPU. There is presently no support for multi-threading, and SharedArrayBuffer cannot create 64-bit memory due to WebAssembly constraints.
The developer intends to use suggested standard modifications and engine updates to fix these problems.Users can run the Stable Diffusion WebGPU example locally by downloading the source code from GitHub.
Furthermore, transformers.js can employ big language models thanks to a patched version of onnxruntime, however its dependability in all circumstances is not guaranteed.
In addition, a pull request will be made to the onnxruntime repository by the developer.
