🤖 Granite 4.0-h-micro LoRA Fine-tuned Model

📋 Model Overview

This model is a parameter-efficient fine-tuned version of IBM's Granite 4.0-h-micro (3.2B parameters), optimized for customer support dialog and recommendation generation tasks. The model leverages LoRA (Low-Rank Adaptation) adapters for efficient fine-tuning, enabling enterprise-grade conversational AI capabilities on consumer hardware.

⚡ Quick Facts

🎯 Intended Use Cases

🌟 Primary Applications

• 💬 Customer Support Chatbots: Automated troubleshooting and user assistance
• 🛍️ Recommendation Systems: Context-aware product and service suggestions
• 🗨️ Dialog Systems: Multi-turn conversational interfaces
• 🏢 Enterprise Customization: Adaptable to domain-specific business data

🚫 Out-of-Scope Use

This model is not suitable for:

• General-purpose question answering outside support contexts
• Tasks requiring knowledge beyond April 2024 (knowledge cutoff)
• Mission-critical applications without human oversight
• Any use case violating the Apache 2.0 license terms

💻 Usage

📦 Installation

pip install unsloth transformers torch accelerate

🚀 Basic Inference

from unsloth import FastLanguageModel
import torch

# Load model and tokenizer
model, tokenizer = FastLanguageModel.from_pretrained(
    model_name="krishanwalia30/granite-4.0-h-micro_lora_model",
    max_seq_length=1024,
    dtype=None,  # Auto-detect
    load_in_4bit=False,  # Set True for 4-bit quantization
)

# Prepare for inference
FastLanguageModel.for_inference(model)

# Chat template
messages = [
    {"role": "system", "content": "You are Granite, a helpful AI assistant."},
    {"role": "user", "content": "I need help choosing a laptop for programming."}
]

inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_tensors="pt"
).to("cuda")

# Generate response
outputs = model.generate(
    inputs,
    max_new_tokens=256,
    temperature=0.7,
    top_p=0.9,
    do_sample=True
)

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

🔄 Advanced: Streaming Generation

from transformers import TextIteratorStreamer
from threading import Thread

streamer = TextIteratorStreamer(tokenizer, skip_special_tokens=True)
generation_kwargs = dict(
    inputs=inputs,
    streamer=streamer,
    max_new_tokens=256,
    temperature=0.7
)

thread = Thread(target=model.generate, kwargs=generation_kwargs)
thread.start()

for text in streamer:
    print(text, end="", flush=True)

🏆 Evaluation Results

The model demonstrates strong performance on customer support tasks:

• ✅ High accuracy on domain-specific Q&A
• ✅ Coherent multi-turn dialog generation
• ✅ Contextually appropriate product recommendations

Note: Formal benchmark scores are pending comprehensive evaluation.

💬 Chat Format

The model uses Granite 4.0's chat template:

<|start_of_role|>system<|end_of_role|>Knowledge Cutoff Date: April 2024. Today's Date: [Current Date]. You are Granite, developed by IBM. You are a helpful AI assistant.<|end_of_text|>
<|start_of_role|>user<|end_of_role|>[User message]<|end_of_text|>
<|start_of_role|>assistant<|end_of_role|>[Assistant response]<|end_of_text|>

The tokenizer's apply_chat_template() method handles formatting automatically.

⚠️ Limitations and Biases

🔍 Known Limitations

1. 🎯 Domain Specificity: Optimized for customer support; may underperform on general-purpose tasks
2. 📅 Knowledge Cutoff: Training data only includes information up to April 2024
3. 💻 Hardware Requirements: Requires minimum 8-12GB VRAM for inference (16-bit) or 4-6GB (4-bit)
4. 📏 Context Length: Limited to 1024 tokens; longer conversations may lose early context
5. 🌐 Language: English only; limited multilingual capabilities

⚖️ Potential Biases

• ⚠️ Training data may contain inherent biases from the support bot domain
• ⚠️ Recommendations may reflect patterns in training data that could favor certain products/solutions
• ⚠️ Users should implement appropriate safeguards for production deployment

🛡️ Ethical Considerations

• 👁️ Transparency: Always disclose AI-generated responses to end users
• 👤 Human Oversight: Implement human-in-the-loop for critical decisions
• 🔒 Data Privacy: Ensure user data handling complies with applicable regulations (GDPR, CCPA, etc.)
• 🚫 Misuse Prevention: Do not use for generating misleading, harmful, or deceptive content
• ⚖️ Bias Monitoring: Regularly audit outputs for fairness and bias

🚀 Deployment Recommendations

💻 Hardware Requirements

🔧 Optimization Tips
