TinyMixtral-x8-Clonebase-7b

Model Card for TinyMixtral-x8-Clonebase-7b

This model is based on TinyLlama-1.1B, converted to a mistral model, and then placed the clone in mixtral.
This model was created experimentally for training a small mixtral.
Without Train, the performance of this model is the same as TinyLlama.

How it was made

First, since tinyllama is an llama model, I converted it to a mistral model.

After that, I cloned the FFN part and made it experts. Since they are all the same tensor, the performance does not change. All gates have the same value.

How To Convert

use colab cpu-high-memory.
This model was created with experts=8, but since it is a clone, you can create as many experts as you like.
