SixFinger-8B Adapter for LLaMA 3.1 8B

This repository contains a LoRA adapter for the SixFinger-8B model.
The adapter allows fine-tuned responses on top of the base model unsloth/llama-3.1-8b-bnb-4bit without modifying the base weights.

---

Overview

• Base Model: unsloth/llama-3.1-8b-bnb-4bit
• Adapter Type: LoRA
• Quantization: 4-bit (via bitsandbytes)
• Purpose: Enhanced response generation for Turkish/English mixed datasets.
• Compatibility: Use with Hugging Face Transformers + PEFT library.

---

Installation

Install required dependencies:

!pip install transformers accelerate bitsandbytes peft

Ensure you have a GPU with sufficient VRAM for 4-bit inference.

---

Loading the Model

1. Load the Base Model

from transformers import AutoTokenizer, AutoModelForCausalLM

    "unsloth/llama-3.1-8b-bnb-4bit",
    device_map="auto"
)

2. Load the Adapter

'from peft import PeftModel'

'model = PeftModel.from_pretrained(' ' base_model,' ' "sixfingerdev/SixFinger-8B"' ')'

3. Load the Tokenizer

'tokenizer = AutoTokenizer.from_pretrained("unsloth/llama-3.1-8b-bnb-4bit")'

---

Example Usage

Generate text using the adapter:

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

# Base model
base_model = AutoModelForCausalLM.from_pretrained(
    "unsloth/llama-3.1-8b-bnb-4bit",
    device_map="auto"
)

# LoRA adapter
model = PeftModel.from_pretrained(base_model, "sixfingerdev/SixFinger-8B")

# Tokenizer
tokenizer = AutoTokenizer.from_pretrained("unsloth/llama-3.1-8b-bnb-4bit")

# Örnek text generation
prompt = "Soru: Yapay zeka nedir?\nCevap:"
inputs = tokenizer(prompt, return_tensors="pt")
with torch.no_grad():
    outputs = model.generate(**inputs, max_new_tokens=50, do_sample=True, temperature=0.7)

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

---

Notes

• The adapter does not modify the base model; it only applies LoRA weights on top.
• 4-bit quantization significantly reduces VRAM usage. Ensure your GPU supports bitsandbytes 4-bit operations.
• You can merge the adapter into the base model for easier deployment if needed.
