# OLMo 2 1124 7B Instruct for Amharic: AdaLoRA

This model is built on top of OLMo 2 1124 7B Instruct adapted for Amharic using 200M target language tokens sampled from MADLAD-400. The model is adapted using the AdaLoRA approach. This is based on https://arxiv.org/abs/2303.10512 and was the best-performing LoRA-based method in the HFT paper.

## Model Description

- **Language:** Amharic
- **License:** Apache 2.0
- **Fine-tuned from model:** [allenai/OLMo-2-1124-7B-Instruct](https://huggingface.co/allenai/OLMo-2-1124-7B-Instruct)


## Model Sources

- **Repository:** https://github.com/gucci-j/ssu
- **Paper:** https://arxiv.org/abs/2512.04844


## How to Get Started with the Model
Use the code below to get started with the model.
```python
from transformers import AutoTokenizer, AutoModelForCausalLM

from peft import PeftModel

base_model = AutoModelForCausalLM.from_pretrained(
    "allenai/OLMo-2-1124-7B-Instruct",
)
model = PeftModel.from_pretrained(
    base_model,
    "ssu-project/OLMo-2-1124-7B-Instruct-am-adalora",
)
model = model.merge_and_unload()
tokenizer = AutoTokenizer.from_pretrained(
    "allenai/OLMo-2-1124-7B-Instruct"
)
```
