Where to find "ComfyUI Kitchen" repository?

So this might sound strange, I'm not sure if the article is hallucinated/badly translated, but in a recent nvidia announcement, they say:

The sample code for the optimizations is available under the ComfyUI kitchen repository. NVFP4 and FP8 checkpoints are also available in HuggingFace, including the new LTX-2, FLUX.2, FLUX.1-dev, FLUX.1-Kontext, Qwen-Image and Z-Image. https://developer.nvidia.com/blog/open-source-ai-tool-upgrades-speed-up-llm-and-diffusion-models-on-nvidia-rtx-pcs/

Again, not 100% sure what they mean with "ComfyUI kitchen repository", do they mean that this Comfy-Org/ComfyUI repository is like a "kitchen sink" in the way we developers use that term (https://en.wikipedia.org/wiki/Kitchen_sink_syndrome), was it just badly translated, or is it referring to a repository that isn't public yet?

It seems like NVFP4 support was added in v0.8.0, so I'm guessing then that the "kitchen" is just added there for .... extra effect?

Hi @embedding-shapes!
You aren't hallucinating! 😅
The "Kitchen" referred to in the NVIDIA announcement is not the Reactflow GUI, but rather the ComfyUI Kitchen kernel library used for acceleration (Triton/CUDA kernels).
It is hosted here:
https://github.com/Comfy-Org/comfy-kitchen
It's a backend library that ComfyUI uses for optimized inference, which is why it's less "visible" than standard custom node repos.
