+# IT Helpdesk AI Classifier — v4
+
+Fine-tuned LLM for classifying IT helpdesk tickets into categories, subcategories, and generating insights for corporate IT support teams.
+
+## Model Details
+
+- **Base Model:** mdk615661/it-helpdesk-merged-v3
+- **Fine-tuning:** QLoRA (LoRA r=16, alpha=32)
+- **Training Data:** 2,000 IT helpdesk records (Qwen-generated)
+- **Training Loss:** 0.187 (3 epochs)
+- **Hardware:** Kaggle T4 GPU (33 min)
+- **Precision:** fp16
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+
+model_name = "mdk615661/it-helpdesk-merged-v4"
+tokenizer  = AutoTokenizer.from_pretrained(model_name)
+model      = AutoModelForCausalLM.from_pretrained(
+    model_name,
+    dtype=torch.float16,
+    device_map="auto"
+)
+
+prompt = """### Instruction:
+Normalize and classify this IT helpdesk ticket.
+
+### Input:
+Laptop is not turning on
+
+### Output:
+"""
+
+inputs  = tokenizer(prompt, return_tensors="pt").to("cuda")
+outputs = model.generate(
+    **inputs,
+    max_new_tokens=150,
+    do_sample=False,
+    repetition_penalty=1.3,
+    pad_token_id=tokenizer.eos_token_id
+)
+print(tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
+```
+
+## Output Format
+Category: Hardware
+SubCategory: Hardware - Laptop
+Normalized: laptop not working
+Priority: Medium
+Insight: Hardware failure preventing user from working.
+Recommendation: Raise repair request with IT hardware team.
