+# Run kolors with onediff (Beta Release)
+
+
+## Environment setup
+
+### Set up onediff
+https://github.com/siliconflow/onediff?tab=readme-ov-file#installation
+
+### Set up compiler backend
+Support two backends: oneflow and nexfort.
+
+https://github.com/siliconflow/onediff?tab=readme-ov-file#install-a-compiler-backend
+
+
+### Set up diffusers
+
+```
+# Ensure diffusers include the kolors pipeline.
+pip install git+https://github.com/huggingface/diffusers.git
+```
+
+### Set up kolors
+
+HF model: https://huggingface.co/Kwai-Kolors/Kolors-diffusers
+
+HF pipeline: https://github.com/huggingface/diffusers/blob/main/docs/source/en/api/pipelines/kolors.md
+
+
+## Run
+
+### Run 1024*1024 without compile (the original pytorch HF diffusers baseline)
+```
+python3 onediff_diffusers_extensions/examples/kolors/text_to_image_kolors.py \
+--saved-image kolors.png
+```
+
+### Run 1024*1024 with compile [oneflow backend]
+
+```
+python3 onediff_diffusers_extensions/examples/kolors/text_to_image_kolors.py \
+--compiler oneflow \
+--saved-image kolors_oneflow_compile.png
+```
+
+### Run 1024*1024 with compile [nexfort backend]
+
+```
+python3 onediff_diffusers_extensions/examples/kolors/text_to_image_kolors.py \
+--compiler nexfort \
+--compiler-config '{"mode": "max-optimize:max-autotune:low-precision", "memory_format": "channels_last"}' \
