Original model: https://huggingface.co/google/gemma-2-2b-jpn-it

## Prompt format

```
<start_of_turn>user
{prompt}<end_of_turn>
<start_of_turn>model
<end_of_turn>
<start_of_turn>model

```

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.

Ten 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 [gemma-2-2b-ORPO-jpn-it-ablitered-18](https://huggingface.co/ymcki/gemma-2-2b-ORPO-jpn-it-abliterated-18).

| Epoch | loss | eval_loss | eval_logps/rejected | eval_logps/chosen |
| ----- | ---- | --------- | ------------------- | ----------------- |
| 1.00 | 0.9754 | 1.0344 | -1.1506 | -0.7516 |
| 2.00 | 0.9629 | 1.0173 | -1.2694 | -0.7351 |
| 3.00 | 0.7435 | 1.0087 | -1.4922 | -0.7388 |
| 4.00 | 1.0595 | 1.0026 | -1.5920 | -0.7310 |
| 5.00 | 1.0525 | 1.0000 | -1.6313 | -0.7311 |
| 6.00 | 1.1628 | 1.0014 | -1.7263 | -0.7393 |
| 7.00 | 0.8994 | 0.9971 | -1.7264 | -0.7324 |
| 8.00 | 0.7448 | 1.0056 | -1.7790 | -0.7482 |
| 9.00 | 0.6801 | 1.0028 | -1.7794 | -0.7429 |
| 10.00 | 0.9868 | 1.0069 | -1.8065 | -0.7505 |

Then I followed Rombodawg's [suggestion](https://www.reddit.com/r/LocalLLaMA/comments/1fyx27y/im_pretty_happy_with_how_my_method_worked_out/) to merge [gemma-2-2b](https://huggingface.co/google/gemma-2-2b), [gemma-2-2b-ORPO-jpn-it-ablitered-18](https://huggingface.co/ymcki/gemma-2-2b-ORPO-jpn-it-abliterated-18) and [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.

The abliterated-18-merge model is slightly better than the abliterated-18 model but slightly worse than the original instruct model.

## 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-merge"
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
