Note that this model does not support a System prompt.

Since [gemma-2-2b-jpn-it-ablitered-18](https://huggingface.co/ymcki/gemma-2-2b-jpn-it-abliterated-18) is slightly brain damaged compare to the original [gemma-2-2b-jpn-it](https://huggingface.co/google/gemma-2-2b-jpn-it). I decided to try ORPO fine tuning to see if it can be headled.

Using the [gemma-2-2b base model](https://huggingface.co/google/gemma-2-2b), I employed the ORPO method described by [mlabonne](https://towardsdatascience.com/fine-tune-llama-3-with-orpo-56cfab2f9ada) but the input model was read into VRAM by [unsloth](https://github.com/unslothai/unsloth) to allow using the full 40k dataset to run on a single 3090.

Five epoches was run. Smallest eval_loss was achieve at epoch 7.00. 
Checkpoint at epoch 7.00 is used to obtain a model adapter and
applied it to [gemma-2-2b-jpn-it-ablitered-18](https://huggingface.co/ymcki/gemma-2-2b-jpn-it-abliterated-18) to obtain this model.

This model is uploaded here to be evaluated by the Open LLM Leaderboard. Further ORPO fine tuning is currently underway to see if it can regain its sanity. You can play with this model first or wait until I am done with the fine tuning.

## How to run this model

```py
from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch

model_id = "gemma-2-2b-ORPO-jpn-it-abliterated-18"
dtype = torch.bfloat16

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    device_map="cuda",
    torch_dtype=dtype,)

chat = [
    { "role": "user", "content": "Write a hello world program" },
]
prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True)
```

## Downloading using huggingface-cli

First, make sure you have hugginface-cli installed:

```
pip install -U "huggingface_hub[cli]"
```

Then, you can target the specific file you want:

```
huggingface-cli download ymcki/gemma-2-2b-ORPO-jpn-it-abliterated-18 --include "*" --local-dir ./
```
