Gemma 2 9b Turkish Lora Continue Pre Trained

🚀 emre/gemma-2-9b-Turkish-Lora-Continue-Pre-Trained

This model is a continued pre-trained version of google/gemma-2-9b, trained on the Turkish Wikipedia dataset. It uses LoRA for fine - tuning to enhance Turkish text understanding and generation.

🚀 Quick Start

You can easily load and use this model using the transformers and peft libraries in Python:

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel
import torch

model_name = "google/gemma-2-9b"
peft_model_id = "emre/gemma-2-9b-Turkish-Lora-Continue-Pre-Trained"

tokenizer = AutoTokenizer.from_pretrained(model_name)

# Load the base model with 4-bit quantization for efficiency
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_use_double_quant=True,
    bnb_4bit_compute_dtype=torch.float16
)
base_model = AutoModelForCausalLM.from_pretrained(
    model_name,
    quantization_config=bnb_config,
    device_map="auto",
    torch_dtype=torch.float16,
    attn_implementation="eager"
)

# Load the LoRA adapter
model = PeftModel.from_pretrained(base_model, peft_model_id)
model.eval()

if torch.cuda.is_available():
    model = model.to("cuda")

prompt = "Türkiye'nin başkenti neresidir?"
input_ids = tokenizer(prompt, return_tensors="pt").to(model.device)

with torch.no_grad():
    outputs = model.generate(**input_ids, max_new_tokens=50, num_return_sequences=1)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))

✨ Features

Model Details

• Commercially only available to BBVA Group, Free to use for academic and research purposes

This model is a continued pre - trained version of the google/gemma-2-9b base model, trained on the Turkish Wikipedia dataset (Alaeddin/wikipedia-turkish). The fine - tuning was performed using Low - Rank Adaptation (LoRA) to efficiently adapt the model to the Turkish language. This model aims to improve the base model's understanding and generation capabilities for Turkish text.

Uses

Direct Use

This model can be used for generating Turkish text for various natural language processing tasks, such as:

• Text generation
• Language modeling
• Creative writing
• Answering questions based on Turkish text (with appropriate prompting)

It is intended for researchers, developers, and enthusiasts interested in exploring and utilizing large language models for the Turkish language.

Downstream Use

This model can serve as a strong base for further fine - tuning on specific downstream tasks in Turkish, such as:

• Turkish text summarization
• Turkish question answering
• Turkish text classification
• Turkish dialogue generation

Out - of - Scope Use

This model should not be used for generating harmful, unethical, or biased content. As a language model trained on a large corpus of text, it may inadvertently generate such content. Users should exercise caution and responsibility when deploying this model.

Bias, Risks, and Limitations

The model was trained on the Turkish Wikipedia dataset, which may contain biases present in the original data. The model's performance may vary depending on the specific task and domain. Users should be aware of these limitations and conduct thorough evaluations for their specific use cases.

Recommendations

Users should carefully evaluate the model's output and consider potential biases before deploying it in real - world applications. Further fine - tuning on task - specific and diverse Turkish datasets can help mitigate some of these limitations.
