GoldenNet-Qwen2.5-0.5B-Full-v1

Model Description

GoldenNet-Qwen2.5-0.5B-Full-v1 is a fully fine-tuned version of Qwen/Qwen2.5-0.5B-Instruct specialized for Iraqi Government Correspondence Processing.

This is the full fine-tuning variant where all 494M parameters were trained, potentially offering the best task-specific performance.

Tasks

1. Document Classification - 8 categories (طلب، شكوى، تقرير، إعلام، استفسار، دعوة، تعميم، إحالة)
2. Named Entity Recognition - Extracts persons, organizations, locations, dates, monetary values, laws

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "Alamori/GoldenNet-Qwen2.5-0.5B-Full-v1",
    device_map="auto",
    torch_dtype="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Alamori/GoldenNet-Qwen2.5-0.5B-Full-v1")

# Classification example
correspondence = """جمهورية العراق

مع التقدير"""

instruction = "صنّف المراسلة الحكومية التالية إلى إحدى الفئات: طلب، شكوى، تقرير، إعلام، استفسار، دعوة، تعميم، إحالة. أجب بصيغة JSON."

messages = [{"role": "user", "content": f"{instruction}\n\n{correspondence}"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.1)
print(tokenizer.decode(outputs[0][inputs['input_ids'].shape[1]:], skip_special_tokens=True))

When to Use This Model

• Use Full-v1 when you need maximum task-specific performance and have sufficient storage/memory
• Use QLoRA-v1 for best balance of quality and efficiency (recommended for most cases)
• Use LoRA-v1 for comparison or when you need standard LoRA compatibility
