# Runs qianfan benchmark, measuring both olmOCR-bench performance and per document processing performance
# Uses baidu/Qianfan-OCR model served via vllm with OpenAI-compatible API

# Usage:
#   ./scripts/run_qianfan_benchmark.sh                                      # Use default model
#   ./scripts/run_qianfan_benchmark.sh --benchrepo allenai/olmOCR-bench-internal  # Use different benchmark repo
#   ./scripts/run_qianfan_benchmark.sh --benchbranch olmOCR-bench-1125      # Use specific branch/revision
#   ./scripts/run_qianfan_benchmark.sh --benchpath s3://ai2-oe-data/path/   # Use benchmark from S3 or local path
#   ./scripts/run_qianfan_benchmark.sh --cluster ai2/titan-cirrascale       # Specify a cluster
#   ./scripts/run_qianfan_benchmark.sh --beaker-image jakep/olmocr-benchmark-0.3.3-780bc7d934  # Skip Docker build
#   ./scripts/run_qianfan_benchmark.sh --noperf                             # Skip the performance test job
#   ./scripts/run_qianfan_benchmark.sh --model baidu/Qianfan-OCR            # Use a specific model
