quantized 8 bit model?
#167
by Roronoa099 - opened
is there any 8 bit or 4 bit quantized model for this
In Brevitas (https://github.com/Xilinx/brevitas/tree/dev/src/brevitas_examples/stable_diffusion) we have a pipeline to quantize SDXL with several command line options to change the quantization configuration.
We support ONNX export to QCDQ format.
I am currently working on updating this script to improve and speed-up GPTQ computation, add FID score vs floating point version and other minor improvements.

Feel free to open an issue/discussion if you have any issue with this. It's being actively developed so bugs could be present.
