# Llama-3 chat vector

- Update 0426: A small problem with the deployment of the model 'Llama-3-Seagull-Evo-8B', but we hope to have it back in good time!
- Update 0526: Check our newest EMM model, [Alpha-Ko-8B-Instruct](allganize/Llama-3-Alpha-Ko-8B-Instruct)

This is 'modelified' version of _chat vector_ from the paper [Chat Vector: A Simple Approach to Equip LLMs with Instruction Following and Model Alignment in New Languages](https://arxiv.org/abs/2310.04799). So this is not a model, its just weight diff, just for ease to use myself(or you too)!

What I understand here:
'Chat vector method' is a merging method that utilizes the difference between the base model, the continuously pre-trained (usually language transferred) model, and the chat model; so the recipe is

`model(base) + weight_diff(continous pretrained) + weight_diff(instruct)` or 

`model(base) + weight_diff(continous pretrained + fine-tuned) + weight_diff(instruct)`.

So before (my) initial purpose in comparing which method is better, `llama3 → CP + chat vector → FT` vs. `llama3 → CP → FT + chat vector`, it seems reasonable to compare it with other methods in [Mergekit](https://github.com/arcee-ai/mergekit).

All that aside, I'd like to thank @[beomi](https://huggingface.co/beomi) for creating such an awesome korean-based model.
