Anyone know when Rust's std::autodiff will become stable? Assuming this Rust support expands to other GPU vendors, autograd will probably be the only reason to use Slang instead of Rust anymore.

I was told in the 2025 LLVM dev meeting that it will always stay in nightly because it's not practical for them to provide long-term stability guarantees that is expected of stable Rust.

Not in 2026.
