Vercel AI Gateway Structured Output Error
#!/usr/bin/env python3
"""
Standalone script to demonstrate structured output issue with Vercel AI Gateway.
This script replicates the functionality of src/ai_news_agent/nodes/summarize_episode.py
but uses Vercel AI Gateway with LangChain ChatOpenAI and structured output.
Expected to demonstrate that .with_structured_output() doesn't work with Vercel AI Gateway.
