    def assess_model_characteristics(self):
        """Analyze model size, architecture, and complexity"""
        return {
            'model_size': self.get_model_size(),
            'parameter_count': self.get_parameter_count(),

BASE_MODEL="microsoft/Phi-3-mini-4k-instruct"

# Phase 1: ONNX Conversion (Universal)
python convert_to_onnx.py --model $BASE_MODEL --output models/onnx/

# Phase 2: Platform-Specific Optimization
if [[ "$TARGET_PLATFORM" == "intel" ]]; then
    # OpenVINO Optimization
    python optimize_openvino.py --input models/onnx/ --output models/openvino/
elif [[ "$TARGET_PLATFORM" == "apple" ]]; then
    # MLX Optimization
    python optimize_mlx.py --input $BASE_MODEL --output models/mlx/
elif [[ "$TARGET_PLATFORM" == "cross" ]]; then
    # Llama.cpp Optimization
    python convert_to_gguf.py --input models/onnx/ --output models/gguf/
