This is abliterated model of google/gemma-2-2b-jpn-it using the method described by mlabonne.
Layer 18 of the original model was chosen for abliteration. I also created another layer 17 abliterated model for comparison.
ORPO fine tuning was performed for four epoches.
| Epoch | loss | eval_loss |
|---|---|---|
| 1 | 1.0452101707458496 | 1.0170862674713135 |
| 2 | 0.81533865332603454 | 0.9825302958488464 |
| 3 | 1.15400108695030208 | 0.9852740168571472 |
| 4 | 0.76560704708099362 | 0.9880287051200867 |
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 is probably 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-18-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-18-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.
