"""
Real integration test for OpenAI Batch API.

This test makes REAL API calls to OpenAI and measures actual timing.
It will be slow (minutes to hours) depending on OpenAI's queue.

To run:
    pytest tests/test_batch_api_integration.py -v -s

To skip in CI:
    Add @pytest.mark.skip at the test level
