Got Easy Diffusion v4 working on Apple and Intel Macs. The performance difference ratio (vs ED v3) is similar to the ratio on Windows (with CUDA) and other deployment targets. So that indicates optimization opportunities in sd.cpp. It's currently about 1.5x slower than diffusers-based Stable Diffusion.

For Z-Image, the performance of the stock version of chromaForge is poorer than sd.cpp's. Mainly because chromaForge isn't able to run the smaller gguf quantized models that sd.cpp is able to run (chromaForge fails with the errors that I was fixing yesterday).

Worked on fixing Z-Image support in ED's fork of chromaForge (a fork of Forge WebUI). Fixed a number of integration issues. It's now crashing on a matrix multiplication error, which looks like an incorrectly transposed matrix (mostly due to reading the weights in the wrong order).

The new engine that'll power Easy Diffusion's upcoming v4 release (i.e. sdkit3) has now been integrated into Easy Diffusion. It's available to test by selecting v4 engine in the Settings tab (after enabling Beta). Please press Save and restart Easy Diffusion after selecting this.

Wrote a simple script to convert ONNX to GGML. It auto-generates C++ code that calls the corresponding ggml functions (for each ONNX operator). This file can then be compiled and run like a normal C++ ggml program, and will produce the same results as the original model in PyTorch.
