"""
Custom LLM multi-benchmark optimization example for Local Deep Research.

This script demonstrates how to run multi-benchmark optimization with custom LLM models.

Usage:
    # Run from project root with PDM
    cd /path/to/local-deep-research
    pdm run python examples/optimization/llm_multi_benchmark.py --model "your-model" --provider "your-provider"
