### Chatty-2x8B
|
||
|
||
## Description
|
||
After some testing, finetuning and multiple merges of Llama-3 LLM models, here is something a little different.
|
||
|
||
This model is a MoE of 2x Llama-3 model trained on different RP format.
|
||
|
||
This repo contains FP16 files of Chatty-2x8B.
|
||
|
||
## The idea
|
||
|
||
I started with two separate Llama-3-Instruct-8B models, each fine-tuned for specific RP formats.
|
||
|
||
Here is two simple exemple of how it was trained.
|
||
|
||
|
||
- **Expert 1**: This model is trained to handle RP that requires actions and descriptions between asterisks. For example:
|
||
```
|
||
*nods* Yes, I understand.
|
||
```
|
||
- **Expert 2**: This model is fine-tuned for plain text RP where characters’ dialogues and actions are described straightforwardly. For example:
|
||
```
|
||
Nods. "Yes, I understand."
|
||
```
|
||
|
||
My initial idea was to make a 11B or bigger Llama-3 model, or just make a 2x8B from existing model, but I got some issues, they were not stable enough, even after DPO and FFT on top my frankenmerge/moe of Llama-3, it was not working well enough to release them.
|
||
|
||
So I just tried the idea of having 2 different RP format trained on 2 separated Llama-3-Instruct-8B, and it worked pretty well!
|
||
|
||
## The dataset
|
||
|
||
Based on Lumimaid 8B OAS success I still used the same "balance" between RP and non RP in the dataset, the maximum was 50% non RP data on each side.
|
||
|
||
RP data was different with some exception, the non RP data was exactly the same, despite that, I can't produce repetition so the double usage of non RP datasets didn't hurt the model in the end.
|
||
|
||
## Prompt template: Llama3
|
||
|
||
```
|
||
<|begin_of_text|><|start_header_id|>system<|end_header_id|>
|
||
|
||
{system_prompt}<|eot_id|><|start_header_id|>user<|end_header_id|>
|
||
|
||
{input}<|eot_id|><|start_header_id|>assistant<|end_header_id|>
|
||
|
||
{output}<|eot_id|>
|
||
```
