This is abliterated model of google/gemma-2-2b-jpn-it using the
method
described by mlabonne.

Layer 17 of the original model was chosen for abliteration.
I also created another layer 18 and 24 abliterated model for comparison.

ORPO fine tuning was performed for four, eight and twelve epoches. Lowest eval
at the end of the fourth epoch was at 3.72 epoch. Lowest eval_loss at the
end of the eighth epoch was 7.48 epoch. Lowest eval_loss at the end of the
twelve epoch was 11.96 epoch. Checkpoint at 11.96 epoch was chosen to generate this model.

The fine tuned model is uploaded here to be evaluated by the Open LLM Leaderboard to see if the slightly brain damaged non-ORPO model can be healed. Again, the fine tuning method is also based on one described by mlabonne but the input model was read into VRAM by unsloth to allow using the full 40k dataset to run on a single 3090.

Looks like fine tuning for 8 epoches is still not enough. May need to run more epoches.

How to run this model

from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch

model_id = "gemma-2-2b-jpn-it-abliterated-17-ORPO"
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-jpn-it-abliterated-17-ORPO --include "*" --local-dir ./

Thank you mlabonne for describing his fine tuning method.

Thanks FullOf_Bad_Ideas from LocalLlama for the suggestion of using unsloth to save VRAM.
