Benchmark LLM Performance on Legal Docs with Sheets & OpenRouter

Automate LLM benchmarking on legal document tasks using Google Sheets test cases, parallel processing, Google Drive, and OpenRouter for efficient model evaluation.

Results are automatically logged back to Google Sheets for analysis. Key benefits include significant
