Llama-3-11B-Instruct-attenuated

Llama-3-11.5B-Instruct-attenuated

The core idea came from @jukofyork, see this issue;

As I understand, The concept of the idea is to make model think twice but leap same distances like original. but why 0.7071067812?

The scale factor to use, eg: solve x^2 = 1/2 --> x = 1/sqrt(2) ≈ 0.7071067812
