"""
Pytest configuration for gpt5_nano_compatibility tests.

These tests require:
- OPENAI_API_KEY or LLM_BINDING_API_KEY environment variable
- Access to OpenAI API with gpt-5-nano model

Since these are integration tests that require external API access,
they are marked with the 'integration' marker and can be skipped
when running unit tests only.
