# Model Card for TinyMixtral-x8-Clonebase-7b
|
| 8 |
+
This model is based on [TinyLlama-1.1B](https://huggingface.co/TinyLlama/TinyLlama-1.1B-intermediate-step-1195k-token-2.5T), converted to a mistral model, and then placed the clone in mixtral.
|
| 9 |
+
**This model was created experimentally for training a small mixtral.**
|
| 10 |
+
|
| 11 |
+
# How it was made
|
| 12 |
+
First, since tinyllama is an llama model, I converted it to a mistral model.
|
| 13 |
+
|
| 14 |
+
After that, I cloned the FFN part and made it experts.
|
| 15 |
+
Since they are all the same tensor, the performance does not change.
|
| 16 |
+
All gates have the same value.
|
| 17 |
+
|
| 18 |
+
# How To Convert
|
| 19 |
+
use colab cpu-high-memory.
|
| 20 |
+
This model was created with experts=8, but since it is a clone, you can create as many experts as you like.
