# 🐃🇹🇭 Buffala-LoRa-TH

Buffala-LoRA is a 7B-parameter LLaMA model finetuned to follow instructions. It is trained on the Stanford Alpaca (TH Translated), Wisesignt, WikiTH, Pantip and IAppQ&A dataset and makes use of the Huggingface LLaMA implementation. For more information, please visit [the project's website](https://github.com/tloen/alpaca-lora).

## Issues and what next?
- The model still lacks a significant amount of world knowledge, so it is necessary to fine-tune it on larger Thai datasets > Next version: CCNet,OSCAR,thWiki
- Currently, there is no translation prompt. We plan to fine-tune the model on the SCB Thai-English dataset soon. 
- The model works well with the LangChain Search agent (Serpapi), which serves as a hotfix for world knowledge. > Plan for Spaces with search chain demo
- Lacked of chat capabilities, waiting for LangChain implementation.
- Colab demo.
- Github for datasets and training notebook.

## How to use

```python

from transformers import GenerationConfig, LlamaForCausalLM, LlamaTokenizer


device = "cuda"

    torch_dtype=torch.float16,
    device_map="auto",
)
model = PeftModel.from_pretrained(
    model,
    "Thaweewat/thai-buffala-lora-7b-v0-1",
    torch_dtype=torch.float16,
)
