All neural accelerator hardware models and all neural accelerator software stacks output slightly different results. That is a truth of the world.
The same is true for GPUs and 3d rendering stacks too.
We don't usually notice that, because the tasks themselves tolerate those minor errors. You can't easily tell the difference between an LLM that had 0.00001% of its least significant bits perturbed one way and one that had them perturbed the other.
But you could absolutely construct a degenerate edge case that causes those tiny perturbances to fuck with everything fiercely. And very rarely, this kind of thing might happen naturally.
