Model Card for Mixtral-Fusion-4x7B-Instruct-v0.1

This model is an experimental model created by merging mistralai/Mixtral-8x7B-Instruct-v0.1 experts.

How we merged experts

Changed to merge using slerp.
Discussion

old merge version
We simply take the average of every two experts.weight.
The same goes for gate.weight.
