My understanding is that Julia still has some way to go before it supports M1. Will Flux.jl automatically support M1 when that happens?

Can it work in the x86 emulator mode for now? Does the GPU also work?

Flux will happily take the blas routines it's given. It only needs the higher abstracted matmuls/ gemm to work, so yes. The GPU targets etc are all a question of how they are targeted by Julia at the moment. We may have some rolling in KernelAbstractions.jl and GPUCompiler.jl but it would require a "frontend" when the language support arrives.

It would be preferable to use the Julia lang slack for similar questions until we are able to get native Julia support for these chips, at which point we can revisit this topic. I'm closing it for now, thanks, hope it helps!

Julia v1.7 is just released with Apple Silicon support on macOS. What does this mean in terms of Flux support for Apple Silicon?

Flux will use the default LinAlg/ blas backend as Julia was built with unless it is overridden explicitly. So as long as regular Julia works on M1, Flux should as well. Unfortunately, I don't have Apple Silicon hardware to run the tests, so if someone wants to run Flux and Zygote tests on the M1, that would be highly appreciated!

@DhairyaLGandhi Given a test script, I can run it and report the results.

The best case scenario hoped for here is using the CPU though, correct? That will be at most, what, 4 times faster (than the current emulated CPU backend)? It would still be too slow for training, though perhaps serviceable for mere inference.

Running the tests from flux and Zygote would be the first step. After which I would run a few examples from the model zoo. And yes it will be using the cpu at the moment. To hook into the the GPU on M1, work is ongoing at https://github.com/JuliaGPU/Metal.jl but it's not ready yet.
