Right, but if the port achieves performance gains over GGML, which is already highly performant, that’s a. Wild b. a signal to move further GGML development into Rust, no?

How would wasm/rust be more performant over c++? I’m not sure the wasm version can take advantage of avx/metal.

Edit: the wasm installer does take advantage by installing plugins.

Unless you’re talking about performance on devices where those two weren’t a thing anyways.

As far as I understand, only the "driver" code is in rust. Everything else is just C++ compiled to WASM. Maybe it's slightly better to have the driver code be in rust than python or scheme or whatever, but I imagine C++ would be basically equivalent (and.... you wouldn't have to go through the trouble of compiling to WASM which likely loses significant performance).

That's what I find weird here. The bit of the code written in rust is almost comically tiny, and the rest is just C++ you compiled to WASM which someone else already wrote. I think comparing this to a Python wrapper for the same code would produce very minimal difference in performance, because the majority goes into performance and formatting the prompt string really isn't that complex of a task. I just don't see what advantage Rust produces here other than the fact that it's a language you can compile to WASM so that you have one binary.

ML has extremely predictable and heavily optimized routines. Languages that can target hardware ISA all tend to have comparable perf and there’s no reason to think Rust would offer much.

There is no mention of it running faster than the original llama2.cpp, if anything it is slower
