Open Minis is a brilliant app, and is based on roughly the same iSH-derived ARM64 core I used for ios-linuxkit (which I wrote about when I released it).
I went all-out on generic Linux runtime support–Alpine, language runtimes, compilers and all the CLI tools I could get working–whereas Minis made the much sharper product choice of using CLI tools as the internals of an iOS agent. That is a brilliant inversion, and much closer to what Siri AI ought to be.
