Following up to the previous post on sdkit v3’s design:

The initial experiments with generating ggml from onnx models were promising, and it looks like a fairly solid path forward. It produces numerically-identical results, and there’s a clear path to reach performance-parity with stable-diffusion.cpp with a few basic optimizations (since both will eventually generate the same underlying ggml graph).

But I think it’s better to use the simpler option first, i.e. use stable-diffusion.cpp directly. It mostly meets the design goals for sdkit v3 (after a bit of performance tuning). Everything else is premature optimization and scope bloat.
