## Summary

Zyphra says rounding small weights to zero makes fewer bits switch, letting AITER run at a higher clock on real inputs but reducing accuracy. Its ZYFA method preserves more of those weights and still finishes sooner because it needs fewer clock cycles.

## Post

Numerics affect hardware behavior. Rounding small weights to zero makes fewer bits switch, allowing AITER to run at a higher clock on real inputs, but harming its accuracy.

ZYFA preserves more of those weights and still finishes sooner, due to requiring fewer clock cycles.
