Parent is correct - the math is very deterministic if you can guarantee it’s running repeatedly on the same machine and you’re not processing “random” requests in parallel. The compiler is irrelevant because once the code is generated it’s not getting recompiled and thus isn’t a source of non determinism (and generally if you don’t touch the math the compiler will consistently emit the same underlying machine code).
This sub-thread was about cloud environments, where different requests may be served by different hardware. And it's in fact very likely that there will be a mix of different hardware from different vendors, in any particular LLM cloud for now.
