+# Prompt Task Complexity Classifier - Quantized
+
+🚀 **A high-performance, quantized ONNX implementation of NVIDIA's prompt task and complexity classifier optimized for fast CPU inference.**
+
+This standalone Python package provides a quantized version of the [nvidia/prompt-task-and-complexity-classifier](https://huggingface.co/nvidia/prompt-task-and-complexity-classifier) with ~75% size reduction and 2-4x speed improvement while maintaining accuracy.
+
+## ✨ Features
+
+- 🔥 **Fast Inference**: 2-4x faster than original model on CPU
+- 📦 **Compact Size**: ~75% smaller model footprint  
+- 🎯 **Comprehensive Analysis**: 8 classification dimensions + complexity scoring
+- 🔧 **Easy Integration**: Drop-in replacement with familiar API
+- 🐍 **Production Ready**: Optimized for server deployment and batch processing
+
+## 📊 What This Model Does
+
+The quantized classifier analyzes text prompts across **8 key dimensions**:
+
+| Dimension | Description | Classes |
+|-----------|-------------|---------|
+| **Task Type** | Primary task category | 11 types (QA, Generation, Summarization, etc.) |
+| **Creativity Scope** | Creative thinking requirements | 5 levels (0.0 - 1.0) |
+| **Reasoning** | Logical reasoning complexity | 5 levels (0.0 - 1.0) |
+| **Contextual Knowledge** | Context understanding needs | 5 levels (0.0 - 1.0) |
+| **Few-shot Learning** | Examples needed | 5 levels (0-4+ shots) |
+| **Domain Knowledge** | Specialized expertise required | 5 levels (0.0 - 1.0) |
+| **Label Reasoning** | Classification reasoning needs | 5 levels (0.0 - 1.0) |
+| **Constraint Handling** | Rule/constraint complexity | 5 levels (0.0 - 1.0) |
+
+Plus a **task-weighted complexity score** that combines all dimensions intelligently based on the detected task type.
+
+## 🚀 Quick Start
+
+### Installation
+
+```bash
+# Install the package with Poetry
+cd prompt-task-complexity-classifier-quantized
+poetry install
+
+# Or install dependencies directly
+pip install torch transformers onnxruntime optimum[onnxruntime] huggingface-hub numpy
+```
+
+### Basic Usage
+
+```python
+from prompt_classifier import QuantizedPromptClassifier
+
+# Load the quantized model
+classifier = QuantizedPromptClassifier.from_pretrained("./")
+
+# Classify a single prompt
+result = classifier.classify_single_prompt(
+    "Write a Python function to implement quicksort with detailed comments"
+)
+
+print(f"Task: {result['task_type_1'][0]}")           # "Code Generation"
+print(f"Complexity: {result['prompt_complexity_score'][0]:.3f}")  # 0.652
+print(f"Reasoning: {result['reasoning'][0]:.3f}")    # 0.750
+print(f"Creativity: {result['creativity_scope'][0]:.3f}")  # 0.250
+```
+
+### Batch Processing
+
+```python
+# Process multiple prompts efficiently
+prompts = [
+    "What is the capital of France?",
+    "Explain quantum computing and write simulation code",
+    "Create a marketing strategy for eco-friendly products"
+]
+
+results = classifier.classify_prompts(prompts)
+
+for prompt, result in zip(prompts, results):
+    task_type = result['task_type_1'][0]
+    complexity = result['prompt_complexity_score'][0]
+    print(f"{task_type}: {complexity:.3f} - {prompt[:50]}...")
+```
+
+### Command Line Interface
+
+```bash
+# Quantize the original model
+prompt-classifier quantize --output-dir ./my_quantized_model
+
+# Test the quantized model
+prompt-classifier test --model-path ./my_quantized_model --benchmark
+
+# Classify prompts from command line
+prompt-classifier classify "Explain machine learning" "Write a sorting algorithm"
+
+# Get model information
+prompt-classifier info --model-path ./my_quantized_model
+
+# Upload to Hugging Face Hub
